Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection boilers, in particular to an environmental protection boiler for reusing the heat of a boiler. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place for burning fuel. The boiler includes two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electric energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production. A boiler that generates steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.

[0003] At present, during the operation of a boiler, a large amount of high-temperature flue gas will be generated. A large amount of heat energy is contained in these flue gases. If these flue gases are directly discharged into the atmosphere, it will not only cause waste of energy, but also cause thermal pollution to the environment. Therefore, it is necessary to recycle and reuse the waste heat of the boiler. Content of the Utility Model
