Precautions for the use of biogas generator sets

Operators must frequently check the inlet lines of biogas generator sets to prevent biogas leakage and excessive condensate from affecting the gas supply.

The newly purchased biogas generator set is recommended to carry out a regular maintenance after 50 hours of operation, because the maintenance of the run-in period of the unit is very important.

When the biogas generator is working, it should be frequently inspected and inspected for the operation of the biogas generator set, and the problems should be adjusted or reported to the relevant leaders in time.

During the operation of the biogas generator, the operator should keep abreast of the load changes and limit the maximum load of the biogas generator.

The filtration unit of the biogas generator should be cleaned regularly.

The biogas inlet pressure of the biogas generator shall not be lower.

The number of generator operating hours, the amount of biogas consumed, and the output power (number of watt-hour meters) are recorded in each shift.

When the biogas generator is started or stopped, the valve should be opened and closed according to the operating procedures to ensure that the pressure in the biogas transmission pipeline is always positive.

The opening and closing states of the biogas pipeline valves of the biogas generator set should be clearly marked.

What things should be paid attention to in the construction of biogas generator sets?

Biogas power generation is a large system, therefore, people must control the biogas fermentation environment to ensure the efficiency and quality of power generation when carrying out biogas power generation. Therefore, the following matters should be paid attention to when building a biogas generator set:

1. Biogas desulfurization and pressure stabilization, explosion-proof device. In addition, in order to prevent the occurrence of the biogas pipeline caused by the backfire of the inlet pipeline, an anti-flashback and explosion-proof device should be placed on the biogas pipeline.

2. Air intake system: A set of biogas-air mixer needs to be installed on the air intake main pipe to adjust the air-fuel ratio and the air intake volume of the mixture.

3. Engine: The combustion speed of biogas is very slow, so there are high requirements for biogas engines.

4. Speed regulation system: The operation of the biogas engine is to run with the generator with the load of electrical equipment, in order to ensure the normal power generation of the generator, the speed regulation system on the biogas engine is indispensable.

The above is the matters to be paid attention to when the biogas generator set is formed, the biogas power generation is environmentally friendly and safe, if you have a need in the biogas generator set, you can call Shandong Huaquan Power, looking forward to cooperating with you.

Biogas power generation in the early stage of generator gas but not power generation treatment method: 1. Prepare the battery in advance and do a good job of magnetizing before work;Second, in the winding than the rated power current is more resistant to the direct current (short time) for magnetization, the specific battery depends on the situation;3. Correct the wiring of the generator set and prepare for polar magnetization; 4. Check whether there are damaged components and replace the problematic circuits in time; 5. Check the dirt and dust on the contact surface of the generator set, adjust the pressure of the brush in time, tighten the brush holder, and make the brush and the slip ring in close contact; Sixth, the pure mu cover to inspect the short circuit of the repair of the first motor unit; 7. Make trouble, connect the joints and repair the contact parts of the switch in time; 8. If there is a fuse, we need to find out the cause in time, and after judging that the circuit of the biogas generator itself is normal, the fuse can be replaced according to the standard.

Pro, the generator uses gas but does not generate electricity in the early stage of biogas power generation may be caused by the following reasons: 1The quality of the biogas is not good enough:

Biogas contains a large number of impurities, such as moisture, hydrogen sulfide, nitrogen, carbon dioxide, etc., if the quality of biogas is not good enough, it will reduce the operating efficiency of the generator, and even fail to generate electricity normally. 2.Generator failure:

There may be faults in the generator, such as poor circuit contact, problems with the motor excitation system, etc., which cause the generator to not work properly. 3.Incorrect generator operating parameters:

The operating parameters of the generator need to be adjusted according to the actual situation of the biogas, such as load size, generator speed, excitation current, etc., if the setting is incorrect, it will also cause the generator to fail to work normally. 4.The operating time of the gas generator set is not enough:

Gas generator sets need a certain running time to enter the normal working state, if the running time is too short, it will affect the performance of the generator set. It is necessary to analyze and troubleshoot according to the specific situation as soon as possible, find out the cause of the fault and repair it in time, so as to ensure the normal operation of the biogas generator.

Hello, here is for you to understand the reasons why the generator uses gas but does not generate electricity in the early stage of biogas power generation: 1The generator is not being started correctly:

Before starting the generator, it needs to be properly commissioned and started according to the steps in the manual. 2.Generator load is not a trouser foot:

Faulty circuit: If the generator output line is damaged or connected incorrectly, it will cause the generator to not work. At this time, it is necessary to check whether the circuit is embedded correctly, whether there are loose or corrosion problems.

4.Insufficient rotor flywheel speed of generator: When the rotor flywheel speed is too slow, it may affect the output voltage and power of the generator, and may lead to unstable work or even complete shutdown.

At this time, it is necessary to check whether the transmission system of the flywheel part is faulty. 5.Generator internal failure:

If one of the components inside the generator fails or is damaged, it can also cause the generator to not function properly. In this case, repairs or replacement of the relevant parts are required.

1. Select the model according to the gas volume. Generally speaking, the thermal power of domestic biogas generator sets is 25% to 39%, and the specificity and model are different, and the power generation power is different. First of all, it is necessary to determine the amount of biogas heat energy, which is related to the total amount of biogas and the heat per unit of biogas.

Because the biogas components are mainly methane and carbon dioxide, the unit of biogas heat only thinks about methane heat.

Second, choose a good manufacturer. At present, there are many varieties of biogas generator sets on the market, generally speaking, there are two kinds of planning and production according to gas characteristics and simple transformation of diesel engines. The gas used in the gas engine, especially the biogas, because the gas pressure and concentration are changed over time, and the incineration condition of the gas is much worse than that of the fuel oil when the cylinder is working, which requires the engine to be accustomed to the gas incineration working condition, and the gas and air share and pressure are conditioned in season, and have perfect incineration control skills, as well as perennial development and accumulation experience and data.

3. Do a good job in the planning, planning and construction of power stations. First of all, it is in line with the safety needs of national power construction, and the planning unit with professional knowledge and experience is requested to supply the plan, and the planning process should be fully connected with the site conditions, so as to save capital as much as possible and give full play to the efficiency of the generator set.

Fourth, select a reasonable and economical level of control. Generally speaking, a dedicated manufacturer will have different equipment equipment to choose from, such as the usual basic type, full active management type and full active operation type three control systems. Usually the basic type unit can achieve the normal operation of the unit;The fully active management type is equipped with a computer management control system, which can intuitively display the operating conditions in an all-round way, actively keep the operation data, and can issue instructions on the computer to control the unitThe fully active control system is a world-class brand of appropriate level of control system, in addition to the full active management function, the unit actively operates, actively adjusts the operating parameters, and the key components are all selected high-end imported products, with high reliability.

1. Gas production rate: the natural temperature is between 10-28 degrees Celsius every day, and the average is 30 cubic meters of gas production per dayIf the fermentation is at medium temperature, the temperature continues to be above 25 degrees Celsius, the average gas production rate is 1, and the gas can be produced 200 cubic meters per day.

2. Under normal circumstances, the gas production is 120 cubic meters a day. If all is used for power generation, domestic generators can generate 96 kilowatts of electricity a day, 1-2 kilowatts of generators can achieve 24-hour power generation, if 2 kilowatts, there is still about 50% of biogas.

If the pig farm is fed once every 10 days, it can also feed 10% of the capacity every day.

4. You can buy two biogas generators to run alternately in spring and autumn, 2 in summer and 1 in winter. Now the biogas generator technology is relatively mature, and it is enough to shut down for half an hour every day. Maintenance is mainly oil, and the average generator is added once a month.

In general, the smaller the power of the gas generator, the greater the gas loss, the gas consumption rate of the 1-2kw gas generator is roughly in cubic meters, theoretically speaking, a 200 cubic meter biogas digester can maintain the generator's 24-hour power supply. However, the biogas digester renovated by private owners, as well as various equipment, will cause biogas loss, which cannot be used well, and the utilization rate of biogas will be reduced, and it may be difficult to complete your task.

Your biogas generator should be serviced with a 3-level technical maintenance approach, 1000-1500h or every other year.

This involves a lot of specific implementation issues, and you have to find an expert to observe and evaluate on the spot, and he will design a feasible plan for you.

Dude, you nb.

But you have to find an expert for this. Or go to the generator manufacturer to find out the situation, you have to have a formal technician to understand your actual situation before you can draw conclusions.

It's not that there is a danger of electricity, and pedestrians should not approach.

If you owe it to the landlord, don't do it blindly!

There are many types of generator sets, and different types of units have different advantages, and users can choose the right unit type according to their specific work needs!

Working principle and advantages of single-fuel biogas generator set: the mixture of "air biogas" is compressed in the cylinder, and the spark plug is used to burn it.

The reciprocating motion of the passing piston is powered, which is then connected to a generator to generate electricity.

There is no need for auxiliary fuel oil and its supply equipment.

The fuel is a system that is simpler to control than a generator set that burns two fuels.

Generator sets** are lower.

Working principle and advantages of dual-fuel biogas-diesel generator set: the mixture of "air combustion gas" is compressed in the cylinder and ignited fuel.

It burns, is powered by the reciprocating motion of the piston, and then connected to a generator to generate electricity.

It can work with either liquid or gaseous fuels.

It can be adapted to changes in biogas yield and methane concentration.

If the switch from gaseous fuel to diesel fuel stops working, there is no unburned gas left in the generator set, because the hunger corrosion resistance is good.

Two types of biogas generator sets disadvantages: the operation is affected by the quantity and quality of the biogas supplied.

Liquid auxiliary fuels are also required when working with gaseous fuels.

Liquid fuel supply equipment is required.

The control mechanism is slightly more complex.

**Slightly higher than single-fuel generator sets.

Specific questions can be communicated with the relevant personnel of our company.

Summary. Yes, biogas power generation needs to meet certain conditions to achieve normal power generation, including biogas quality, generator load, etc. If the biogas quality is insufficient or the load is insufficient, it may lead to the generator consuming the biogas in the early stage but not generating electricity.

Specifically, the following conditions need to be met:1Biogas quality should be good:

The methane content in biogas reaches more than 70%, and at the same time, it is necessary to avoid containing harmful gases such as hydrogen sulfide in biogas; 2.The load of the generator should reach full load operation: when the load of the generator is too low, the generator cannot operate normally, and it needs to meet certain load requirements to start and run; 3.

The equipment is in good operating condition: all components of the biogas power generation equipment must be in normal operating state, such as generator windings, governors, cooling systems, etc., in order to ensure the normal operation of the equipment. If all the above conditions are met, there is still a situation where biogas is consumed in the early stage but no electricity is generated, and the status of the equipment needs to be further checked, and there may be faults or adjustment problems.

It is advisable to contact a professional for inspection and repair.

Biogas generators consume biogas but do not generate electricity in the early stage. Is it because the conditions for full operation are not met?

Yes, biogas power generation needs to meet certain conditions to achieve normal power generation, including biogas quality, generator load, etc. If the biogas quality is insufficient or the load is insufficient, it may lead to the generator consuming the biogas in the early stage but not generating electricity. Specifically, the following conditions must be met:

1.The quality of biogas should be good: the methane content in biogas should reach more than 70%, and at the same time, it is necessary to avoid harmful gases such as hydrogen sulfide in biogas; 2.

The load of the generator should reach full load operation: when the load of the generator is too low, the generator cannot operate normally, and it needs to meet certain load requirements to start and run; 3.The equipment is in good working condition:

All components of biogas power generation equipment must be in normal operating condition, such as generator windings, governors, cooling systems, etc., to ensure the normal operation of the equipment. If the above conditions are met, there is still a situation where biogas is consumed in the early stage but no power is generated, and the status of the collapsed equipment needs to be further checked, and there may be faults or adjustment problems. It is advisable to contact a professional for inspection and repair.

So where does the biogas consumed in the early stage go?

In the case of the biogas consumed by Henglianghu in the early stage, it may have been used by the system for heating or combustion, but it has not yet generated enough energy to start the generator, and the slag may have been discharged.

Oh, that means the biogas is not stored in the generator.

Yes, biogas needs to go through a series of treatments and conditionings before it enters the generator to meet the requirements of the generator and the modification. In the process, some of the biogas is consumed, but not stored in the generator. The generator can only generate electricity normally if it meets its working requirements, otherwise it will not be able to generate electricity even if there is biogas**.
