The invention discloses an energy-saving chain boiler coal grinding machine provided with a warm air supply system. The energy-saving chain boiler coal grinding machine comprises a driving mechanism, a coal inlet box, a coal grinding assembly, an air inlet pipe and a coal powder conveying pipe, wherein the air inlet pipe is communicated to a warm air supply system, and the further improvement comprises that a flow rate control valve is arranged inside the air inlet pipe and the outer wall of the air inlet pipe is provided with a thermal insulation layer. According to the present invention, the energy-saving chain boiler coal grinding machine has characteristics of high coal grinding efficiency, precise control of the volume of the air input into the coal grinding machine, low energy consumption, and good energy saving effect.
Description
technical field [0001] The invention relates to a boiler coal pulverizer, in particular to a chain boiler coal pulverizer. Background technique [0002] At present, coal-fired boilers are the main boilers used in the production of small and medium-sized enterprises in my country and urban central heating. The social ownership of steam boilers below 75t / h and hot water boilers below 58 MW is about 570,000 units, of which chain boilers account for 70. %about. Commercially available chain boilers are generally equipped with coal pulverizers. The existing chain boiler coal pulverizer comprises a driving mechanism, a coal feeding box, a coal pulverizer assembly, an air intake pipe, and a pulverized coal conveying pipe, and the air intake pipe sucks air from the environment and transports it to the coal pulverizer. The chain boiler coal pulverizer has a relatively simple structure, but the temperature of the air entering the coal pulverizer is low, which affects the coal pulveriz...
