Description

Technical Field

[0001] The utility model relates to the technical field of power generation energy saving, in particular to an energy saving device for a boiler in a thermal power plant. Background Art

[0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy in the fuel and electrical energy. The boiler outputs steam with certain thermal energy, high-temperature water or organic heat carrier. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives. In the power plant, the steam generated in the boiler can be first converted into mechanical energy through the steam power device, and then the mechanical energy can be converted into electrical energy through the generator to achieve power generation. Existing boilers generally use coal or garbage as fuel. When they burn, they will produce a lot of flue gas, which has a lot of heat. Power plants generally discharge the flue gas directly, which is not only not environmentally friendly, but also causes a certain amount of energy waste.

[0003] An energy-saving and environmentally friendly boiler, authorization announcement number: CN216244370U, solves the problem that existing boilers generally use coal or garbage as fuel, which will produce a large amount of flue gas during combustion. The flue gas contains a large amount of heat, while power plants generally discharge the flue gas directly, which does not meet the use needs.

[0004] However, it also has certain defects during use, such as the inability to control the amount of air in and out, and the inability to control the amount of smoke discharged. During long-term use, impurities in the smoke will cause the filter to be blocked, thereby affecting the filter's filtering effect on the smoke. Utility Model Content

The baffle 5 adopts a diamond structure, and the baffle 5 can rotate on the second disc 4. The baffle 5 that is rotated and opened forms an air hole, and the size of the air hole can be adjusted at the same time, thereby controlling the air intake, changing the coal combustion rate, thereby controlling the efficiency of heat generation, and changing the power generation;
