Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a high-efficiency coal-fired boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in coal 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 coal. 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. With the development of society, boilers are used when coal needs to be converted into energy.

[0003] Existing equipment such as CN202311423468.7, a high-efficiency coal-fired boiler, includes a combustion boiler body. An upper outlet pipe is fixedly installed at the upper end of the combustion boiler body. A return pipe is fixedly installed at the upper end of the upper outlet pipe. A conveying pipe is arranged on one side of the lower end of the combustion boiler body. A processing part is fixedly installed at the end of the conveying pipe away from the combustion boiler body. One end of the conveying pipe extends into the processing part and is fixedly installed with a guiding hopper. An upper mounting plate is fixedly installed on the upper surface of the processing part at the position corresponding to the guiding hopper. The end of the return pipe away from the upper outlet pipe passes through the upper mounting plate and extends into the processing part. A feed inlet is arranged on one side of the upper mounting plate on the upper surface of the processing part. A crushing component is arranged in the feed inlet. The crushing component can evenly crush the boiler combustion raw materials into fine particles, a coal-fired boiler that enables the coal to burn more fully and has a higher combustion efficiency.

[0004] At present, most workers usually use auxiliary tools to put coal into the boiler so that the boiler can convert the coal into heat. However, during the feeding process, the coal is unevenly stacked, resulting in the situation that the air required for some coal during combustion is blocked by combustion waste, thereby causing the problem of reduced combustion efficiency of the boiler.
