Working principle of power station boiler

Working principle of power station boiler

Working principle of power station boiler

The function of the boiler is to convert the chemical energy of the fuel into heat energy, and use heat energy to heat the water in the boiler to make it superheated steam with sufficient quantity and certain quality (steam temperature and pressure) for use by the steam turbine. Currently, boilers in thermal power plants have large capacity, high parameters, complex technology, and high levels of mechanization and automation. Therefore, the fuel is mainly coal, and coal is first made into pulverized coal before combustion, and then sent to the boiler for combustion and heat release in the furnace. To sum up, the main working processes of a boiler are fuel combustion, heat transfer, water heating and vaporization, and steam overheating. The entire boiler consists of two parts: the boiler body and auxiliary equipment. Let me briefly introduce their composition.

Maintenance of boilers and heating systems

After a period of boiler operation, due to water quality reasons, scaling often occurs inside the boiler. These phenomena not only encroach on the volume of the boiler, but also the thickness of the scaling can have a significant impact on the heat supply of the boiler. According to experiments, 1 mm of scaling in the boiler increases fuel consumption by 3%, so it is necessary to properly handle the water. In the current environment, a commonly used water treatment method is to use a sodium ion countercurrent regeneration exchanger. This equipment has a strong adaptability to raw water, and the water output and quality of the treated water are relatively good. The water treatment effect is relatively ideal. In addition, vacuum deoxidization is also used for water treatment in some large and medium-sized boilers. Compared to atmospheric deoxidization, vacuum deoxidization can save a lot of fuel and reduce the loss of exhaust smoke.

Select appropriate fuel and combustion mode for boiler use

"The fuel that consumes most in the use of boilers is fuel. To take energy-saving measures, it is necessary to start with the selection of fuel.". Under current socio-economic conditions, there are three main types of boiler fuels, namely, solid fuel, gas fuel, and liquid fuel. These three different fuels generate different amounts of heat and pose different levels of harm to the environment. On the whole, gaseous fuels have great advantages in terms of heating quality and environmental protection, and should be given priority when selecting fuels. However, in some boiler heating systems, due to the impact of production processes and fuel supply capacity, the selection of gaseous fuels is still subject to certain restrictions. In the selection of fuel oil, due to its high cost, it is often more expensive to choose this fuel for boiler heating. Currently, it is feasible to use briquette and vaporize it before using it. This way, there is less residue after combustion, and the amount of exhaust gas emitted during excessive combustion is also small. Moreover, the calorific value of combustion of briquette after vaporization is relatively high, so it is more cost-effective to use it in boiler heating.

What should be paid attention to when selecting biomass boilers

Currently, China is vigorously promoting the application of biomass briquetted fuel boilers, large-scale biomass fluidized bed direct combustion boilers, biomass centralized heating boilers, biomass cogeneration boilers, and biomass coal-fired coupling power generation boilers. More biomass fuels such as straw and rice husk have been better comprehensively utilized. Of course, there are also some customers in Shenzhen, Guangzhou, and other places who consult about the situation of biomass boilers, but in places such as Shenzhen, The construction of biomass boilers has been banned because many enterprises used biomass boilers to burn coal at that time, and this situation has emerged endlessly. Therefore, the application of biomass boilers has been directly prohibited locally. This approach is understandable, but for some major agricultural provinces, it is better to "treat them differently", otherwise it will cause a significant waste of biomass fuel.
