What are the heating methods of industrial boilers?

industrial boilers are important thermal energy supply equipment in the national economy. Electric power, machinery, metallurgy, chemical industry, textile, paper, food and other industries, as well as industrial and civil heating all require boilers to supply a large amount of thermal energy. Here, ZOZEN Boiler summarizes the heating methods and principles of industrial boilers, hoping to help everyone.

Generally speaking, the heating methods of industrial boilers mainly include conduction, convection and radiation in terms of heat transfer methods. In the form of heating equipment, there are stratification, room combustion and boiling combustion. Here we mainly introduce the heating methods of centralized industrial boilers in different forms of heating equipment:

One of the heating methods of industrial boilers is chamber combustion
Chamber combustion is also called suspension combustion. It is a combustion method in which fuel is sprayed into the furnace in powder, mist or gas state with air for combustion. Suspension combustion ignites quickly, has fast combustion reaction, and has high thermal efficiency. It is easy to realize automatic operation and adapt to the outside world. The ability of load changes is strong, and the adaptability to fuel is strong.
Chamber furnaces include pulverized coal furnaces, oil-fired boilers and gas-fired boilers, which are a relatively common heating method for industrial boilers.

The second heating method of industrial boilers is layered combustion

Layered combustion is also called firebed combustion. It is a method of distributing fuel on the grate with a certain thickness for combustion. It is only suitable for solid fuels. Layered combustion can adapt to various types of coal. Coal particles do not need special processing. The standard plus the combustion intensity can achieve the ideal combustion condition.

There are many types of layered combustion equipment, including hand-burning grate, double-layer grate, chain grate, reciprocating grate and coal thrower furnace. way replaced.

The third heating method of industrial boilers is boiling combustion

Boiling combustion is the combustion of fuel in a fluidized boiling state under the action of air at an appropriate flow rate in a fluidized bed. Boiling combustion is suitable for all kinds of coals, which can greatly reduce the formation of serious cancerous nitrides. Desulfurization measures can be taken to protect the environment.

The agitation and mixing of coal particles and air in the coal seam are particularly strong, so the heating conditions of coal particles are good, and the adaptability to coal types is very wide, especially low-volatile, high-ash, low-calorie low-quality coal can be burned, yes New clean coal combustion technology.

The fourth heating method of industrial boilers is gasification combustion

Gasification combustion mainly refers to the gasification and combustion of coal put into the furnace. This combustion method is not suitable for coal with low volatile content. The gas contains chemical substances. We should pay attention to the ears and nose during use, and avoid accidents. One of the more heating methods of industrial boilers.

The above is the introduction of the heating method of industrial boilers. If you still do not understand, please consult the online customer service of ZOZEN Boiler, ZOZEN Boiler will provide you with boiler selection, design, production and installation of one-stop boilers Serve.
