Which type of combustion is more energy efficient in the boiler?

I'm an oilfield heating system! We have both steam heating and hot water heating! I think your question is good!

First of all, I have to make sure that your boiler should be coal-fired and not oil-fired!

If it is a light (high alumina fiber plate) furnace wall with fuel oil, due to the poor heat storage of the furnace, the fuel temperature is reduced due to the intermittent operation of the boiler, and diesel (natural gas) must be used for re-ignitionIt's clear that the intermittent type is not suitable!

If it is a coal-fired heavy (poured) furnace wall, intermittent operation can be properly considered!! However, changes in gas load cannot be ignored. If it is directly steam heating, the load changes greatly, so it is recommended not to use the intermittent type! If it is heat exchange with steam, the load is relatively stable, you can consider!

In fact, the level of operation has reached a certain level, and the operation method is not so important! You should consider more advanced energy-saving equipment and processes!! For example:

Coal-fired additives, oxy-fuel combustion equipment (process), composite phase change heat (technology), weak ash cleaning system, briquette in front of the furnace, etc.

For example, when we drive, do we always keep 90 miles to save energy? Or do you first accelerate to 130 mph, then coast to 90 mph in neutral, and then accelerate to save energy!?

It depends on the road conditions and how far you are traveling. And so on!! In fact, after your driving level reaches a certain height, the most important thing is how well your car is equipped!!

It is more energy-saving to burn to the specified pressure, and the wind pressure and grate speed should be controlled, which should be adapted to the load of production steam (hot water).

The pressure of the boiler is high and low, which has a certain damage to the boiler, the parameters are stable, and the service life of the boiler is long.

Try to avoid exhausting to the air, and various parameters should be reasonably configured according to the use load, which requires a certain amount of experience of boiler workers.

This is not to be considered, of course it is coal.

Personally, I think that smooth combustion is more energy-saving, because the boiler is frequently started and stopped, and the fan purge will take away part of the heat when it starts and stops.

There are three forms of combustion in boilers: laminar combustion (bed combustion), chamber combustion (suspension combustion), and boiling combustion. Each combustion method has its corresponding combustion equipment.

Fixed grates, chain grates, reciprocating grates, vibrating grates, etc. belong to the layer combustion type, which is suitable for burning solid fuels. Pulverized coal boilers, oil-fired boilers, gas boilers, etc. belong to the room-fired type, which is suitable for powdered solid fuels, liquid fuels and gaseous fuels. Bubbling fluidized bed and circulating fluidized bed belong to the boiling combustion method, which is suitable for burning granular solid fuels.

The chain grate of the coal thrower has both layer combustion and chamber combustion methods, which belongs to the mixed combustion mode.

Hello, 1.The methods and methods of boiler combustion include suspension combustion, layer combustion, bed combustion, vulcanization combustion, etc. For example, pulverized coal furnaces, chain furnaces, circulating fluidized bed boilers, and so on.

2. There is a general idea of how to adjust the combustion, such as adjusting the air volume, the amount of powder and coal, etc.

Hello, if you are in your own home in the winter boiler heating before you must clean the cinders, just light the coal to put small pieces and soap size on the line, don't put too little wood for ignition, don't put coal and too big pieces, after the fire is big, put a small piece of a stove, how to add it later, it's okay, especially the noodles are not extinguished with water. When the fire is big, don't break it, and the temperature in the house is slower. If you don't add a fire in the morning until noon, don't try to save trouble and put coal in it to re-lead, according to the above method.

Absolutely.

I will find out how to burn the energy-saving boiler for you: the incineration of the energy-saving boiler, an important member of the boiler, is also called the ignition. Let's first understand from the concept, in the cold combustible mixture, the cold here refers to the temperature does not reach the ignition point, if the temperature rises to a certain extent, spontaneous combustion will occur, and it will not be ignited, with a small point heat source, detailed to the gas energy-saving boiler, which is mainly completed by using the incineration transformer and incineration electrode of the incinerator, which makes the combustibles partially heated and ignited by the mixture of a certain heating temperature.

Then, through a vigorous chemical response, the flame fills the entire furnace with combustible gas, a process that we call incineration. Why do you say gas boilers? As the small coal-fired boiler has been told by China's laws and regulations, it is now at the end of the product cycle, and will be screened on a large scale by the first shopping mall in the future, and the energy-saving boiler using natural gas as fuel is gradually becoming the main stream.

In some relatively remote areas, perhaps the gas pipeline is not laid in place, then the use of electric heating energy-saving boilers, other fuel boilers have relatively small advantages, and they are not the main products in China

Many experts and scholars in different industries such as thermal energy experts and boiler technology experts have found that in the field of heating, gas hot water boilers are more energy-efficient than gas steam boilers, and some heating projects will also change the heating of steam boilers to hot water boilers for heating according to energy-saving requirements. However, many applications such as hospitals and hotels that require both steam and hot water need to make a specific analysis of what kind of equipment is more suitable to choose. If the heating system uses a large amount of hot water and requires a small amount of steam, it is recommended to have a small steam boiler or steam generator in addition to the hot water boiler to meet the small steam demand.

For example, the steam demand of hospitals or star-rated hotels does not exceed 30% of the total heat demand, and according to the actual use experience, in addition to the problem of large attenuation of its own efficiency in the low-load operation state, the energy consumption loss of the system is greater, and the final energy utilization rate is generally only about 60%, and the energy waste is serious. In general, the energy-saving advantages of gas hot water boilers are more obvious than steam boilers in the heating system of commercial sites.

To sum up, for heating and hot water supply alone, gas hot water boilers are more suitable, more energy-saving and better to use than gas steam boilers, but if you not only want the boiler to provide heating and hot water, but also want the boiler to play other purposes, you need to consider it according to the actual situation.

Hot water boilers are more energy-efficient than steam boilers for the following reasons: first, because the heating temperature of hot water boilers is low, the general hot water outlet temperature is between 110-150 degrees, and all the sensible heat has no latent heat when heating; Secondly, the combustion temperature of the boiler is low, the exhaust gas temperature is also low, and the loss is small; Third, the temperature of the hot water sent is low, and the heat dissipation loss of the pipeline is small; Fourth, there is no need for continuous sewage discharge, and the loss is small; Fifth, fuel can be of inferior quality and the cost of fuel is low.

Personally, I think that hot water boilers are more energy-efficient, and the conditions for steam generation are 100 degrees Celsius.

1. Gas boiler fire chamber combustion: The fuel is sprayed into the furnace with powder (coal), mist (oil) and gaseous (gas) for suspension combustion, and its equipment becomes a chamber combustion or suspension furnace.

2. Gas boiler burning: the fuel is layered on the grate, the air is trapped through the fuel layer and enters the furnace through the gap gap of the grate, and most of the fuel is burned in layers on the grate, and a small part of the fine particles and combustible gas precipitated from the fuel void layer are burned in the space of the upper part of the fuel layer, and its equipment becomes a bed furnace, layer combustion furnace or grate furnace.

3. Cyclone combustion of gas boiler: it is characterized by the tangential or axial flow of fuel gas into the cyclone cylinder.

4. Gas boiler boiling and combustion: the air is evenly fed into the furnace through the air distribution plate at an appropriate flow rate to blow up the coal particles

Energy saver, literally means to save energy.

The principle of the economizer is to reduce the exhaust gas temperature (the exhaust gas temperature is required by the country), and the reverse balancing efficiency of the boiler is improved;

On the other hand, the heat replaced by the economizer is returned to the boiler, which is equivalent to increasing the inlet and return temperature of the boiler, and the coal consumption is reduced under the condition that the boiler output is constant.

It doesn't have to be used, but if you think you need to save some costs, then install it, and the energy saver is also a big expense.

If the boiler itself wastes energy, the state will control and restrict its use.

It's definitely energy saving. It is to replace the heat discharged from the flue to the water entering the boiler, so that the temperature of the boiler inlet water is high, is it saving energy.

Oil, gas, coal through combustion to produce high-temperature flue gas release heat, high-temperature flue gas first into the furnace, and then into the front smoke box waste heat ** device, then into the smoke pipe, and finally into the rear smoke box flue gas in the waste heat ** device, high temperature flue gas into low temperature flue gas through the chimney into the atmosphere. Because the waste heat boiler greatly improves the utilization rate of the heat released by fuel combustion, this kind of boiler is very energy-saving. Due to the complex manufacturing process, the production cost of the waste heat boiler is high, so the boiler is expensive.
