How to install the natural gas burner, how to adjust the natural gas annealing furnace and the burne

The installation of natural gas burners needs to pay attention to the following problems and solutions.

1) The burner ignition electrode or the ceramic tube installed on the detection electrode is damaged during transportation, resulting in a short circuit and cannot produce sparks.

Solution: After arriving at the customer's site, first check the equipment and replace the ceramic tube in time; Business travelers carry spare ceramic tubes with them.

2) The ignition electrode of the ignition burner is too close to the tube wall, which produces an intermediate ignition, and the tip spark is small, causing ignition failure.

Solution: When installing or replacing the ignition electrode, the ion needle should be straight to avoid the middle bending caused by the excessive length of the ion needle; According to the working conditions of the site, an appropriate cannula is added in the middle to increase the gap between the ion needle and the tube wall.

3) The connection between the ion needle and the high-pressure cap is ignited, resulting in the phenomenon that the tip is not ignited.

Solution: There are two kinds of high-voltage caps, one needs to install a copper cap, and the other needs to remove the copper cap. When there is ignition at the plug joint, check whether the copper cap is reliably installed, whether there are conductive substances such as oil stains at the connection, and remove it in time.

4) There is no thread connection for the burner air duct or trachea.

Solution: If the tapping is missed in the burner production process, the burner end screw can be removed directly and only returned to the factory.

How to install a natural gas burner in the actual process, you can consult the burner manufacturer!

Natural gas burners depend on what kind of burners you use, if it is metal, it is generally possible without hard installation, you need to reserve burner mounting holes, install flanges and burner bricks, etc. If it is a burner with refractory bricks, the general requirement is hard installation, and the installation hole should also be reserved and the flange should be installed. The gap between the burner brick and the reserved monolithic castable should be tightened with a cotton plug.

How to install it or communicate with the burner manufacturer.

The natural gas burner shall be installed at the outlet of the gas pipeline according to the required instructions, and the gas pipeline shall be equipped with filters, pressure reducing valves, manual shut-off valves, pressure gauges, proportional valves, etc., and the electronic control system shall also need to install multiple solenoid control valves to ensure production safety specifications.

The manufacturer will adjust the natural gas burner according to your requirements before leaving the factory, and it is recommended to consult the manufacturer at that time to adjust it again after leaving the factory.

Hello, what do you want to adjust, is it the size of the flame, or the atmosphere of the burning.

The flame size of the burner of the natural gas annealing furnace can be adjusted by the combustion pressure of the gas pipeline air duct.

Depending on your purpose, decide how to tune it.

Natural gas burner is a commonly used combustion device in industrial kilns, the performance of natural gas burner will greatly affect the quality of the product, reasonable and efficient natural gas burner can meet the requirements of the kiln combustion, heating and product process.

The burner is a common name for the combustion device used in industrial fuel furnaces, which can be understood as the abbreviation of "nozzle for burning fire". It usually refers to the combustion device body, which has a fuel inlet, an air inlet and an ejection hole, which plays the role of distributing fuel and combustion air and combusting after spraying out in a certain way.

Burners are divided into many according to different furnace types and process requirements.

Esapyronics high-speed, low-nitrogen burners.

Fine-burned, low-nitrogen burner.

1) Natural gas burners can be used in power generation and industrial raw material industries.

In the field of power generation and industrial fuels, the thermal efficiency of natural gas is about 10% higher than that of coal, and the environmental benefits are very prominent. Compared with the traditional centralized energy supply mode, natural gas distributed energy is a more efficient way to use energy, and the cascade utilization of energy is realized through combined cooling, heating and power generation, and the heating efficiency is nearly twice that of coal-fired power generation. The CO2 emissions from the combustion of natural gas are 59% of that of coal and 72% of that of fuel oil.

2) Natural gas burners can be used in processing and manufacturing and chemical industries.

Natural gas has gradually replaced oil and coal in industries such as food processing, glass, steel, ceramics, chemical refining, hydrogen production, synthetic ammonia, and methane. For example, Yanjing Beer, which we are all very familiar with, has completed the "energy revolution", and natural gas has become the main energy source for their production. Not only is it highly combustion-efficient, but it is also environmentally friendly.

Some burners are common for liquefied gas and natural gas, but there are still differences for most burners, mainly because the calorific value of natural gas and liquefied gas is different, so the most obvious thing about natural gas burners is that the diameter of the gas supply pipe is different, and the internal structure of the burner is also different.

Industrial gas furnace customers often ask such a question when selecting a burner, can your burner natural gas and liquefied gas be universal? In fact, as long as this issue is mentioned, one of their orientations can be roughly judged, generally speaking, the natural gas pipeline network in some areas cannot be laid for the time being; The cost of transporting compressed natural gas or liquefied natural gas cannot be delivered. In this case, business leaders may consider using liquefied gas as fuel and then switching to natural gas or other gas.

The question arises, after a year and a half, if other gas is replaced, can these combustion equipment continue to be used? If not, it will be a waste of some resources and an increase in input costs. Therefore, the person in charge of the factory will ask if the two burners can be used together.

In fact, the problem itself mentioned by the customer is inaccurate, people who know the design of the burner know that the exchange of burners is actually irreversible, that is to say, one gas burner can be used as another gas burner, but the other may not be suitable for the former. Therefore, it is not accurate to say that the burner is "universal" and "interchangeable", but many people are used to it, so there is no need to delve into it, as long as the designer can understand the user's intention.

It is not recommended to use one burner for both natural gas and liquefied gas. Although I do not agree with the use of one burner for two types of gas, not all combustion equipment can not be universal, some designers can fine-tune part of the structure design at the beginning of the design, but most of the burner structure is difficult to change or the change is incorrect, the gains outweigh the losses. It seems that the equipment saves some investment, but in fact, the loss is far more than that.

If the situation in use belongs to this type, there are also ways to save the burner under the premise that the power of the burner is not particularly large, and the burner structure can be slightly modified to make the burner perfect as much as possible.

1. The total heat required by the kiln (total gas consumption), or the gas consumption of a single burner.

2. The type, pressure, stability, calorific value, density, viscosity of the fuel used, whether it contains impurities and the gas supply system and equipment.

3. Combustion air temperature, air supply equipment and system.

4. The size of the combustion chamber, the thickness of the furnace wall, the installation location, the shape, direction, temperature, and atmosphere of the flame are required.

5. Furnace pressure and high temperature conditions.

6. Adjust the requirements, automatic or manual.

7. Ignition device and matching conditions, flame-out conditions and requirements.

1. First of all, understand the main components of natural gas and coal gas.

2. Because the main components of natural gas and gas burners are different, the amount of oxygen required is different when distributing air to the burner, that is, the amount of air required for complete combustion of natural gas and coal gas with the same standard of 1 standard is different.

3. If the carbon content in the gas is large, it also involves the problem of the excess coefficient of air, and the excess coefficient of the air required for natural gas and gas combustion can also be set differently. It depends on the adjustment of the combustion situation.

Having said all this, the difference is the size and number of air or oxygen nozzles in the burner.

No, the structure in the slippery brother is different, and if you must use the dust, it will lead to higher gas use and lower burner life.

Some burners are common to liquefied gas and natural gas, but there is still a difference between most burners, mainly because the calorific value of natural gas and liquefied gas is not the same, so the most obvious thing about natural gas burners is that the diameter of the gas supply pipe is different, and the internal structure of the burner is also different.

No, because natural gas is methane, it consumes more oxygen than liquefied gas, and large burners should be used, otherwise carbon monoxide may be produced and health is threatened.

Of course, it can't be a state of loss, it must be the same kind of gas.

Interchangeability. That is, the same type of gas.

Cooker. in order to be universal. Burn and dismantle.
