Abstract

The invention discloses a double-cone inverse-spray pulverized coal burner capable of preventing overheating deformation of a primary air pipe. The double-cone inverse-spray pulverized coal burner ischaracterized by comprising a precombustion chamber and the primary air pipe, wherein the outlet end of the primary air pipe is arranged in the precombustion chamber; the inlet end of the primary airpipe is located outside the precombustion chamber; a cooling system used for cooling the primary air pipe is arranged at the inlet end of the primary air pipe. The temperature of the primary air pipecan be effectively reduced by a water-cooling system or an air-cooling system, and the problem that the primary air pipe is prone to occurring overheating deformation is solved.

Description

technical field [0001] The invention relates to a double-cone burner, in particular to a double-cone reverse injection pulverized coal burner which prevents the primary air pipe from overheating and deforming. Background technique [0002] The double cone burner has the characteristics of quick start and stop, low load and stable combustion. In the long-term industrial application, it has been proved that the burner can be used in many occasions. The primary air duct is an important part of the double-cone burner. The ambient temperature it withstands exceeds 1000°C, and the operating environment is very harsh. The material requirements for the primary air duct are strict and the cost is high. The phenomenon of overheating and deformation of the air duct occurs from time to time, and the furnace must be shut down for replacement, which has a great impact on the economic benefits and production tasks of the enterprise. [0003] After analysis, there are three main reasons f...
