Abstract

The invention discloses a high-efficiency clean pulverized coal combustion industrial boiler device in the field of combustion devices with combustors. The high-efficiency clean pulverized coal combustion industrial boiler device comprises a hearth, a cyclone pulverized coal burner, a high-temperature vortex burnout device, a transition chamber, a convection flue and a tail flue, wherein the high-temperature vortex burnout device is arranged at an upper outlet of the hearth; the cyclone pulverized coal burner is arranged on the front and rear walls or the left and right walls on the lower part of the hearth in a hedge mode; the transition chamber is arranged on the rear part of the high-temperature vortex burnout device; the inlet of the convection flue is connected with the rear part of the transition chamber; the outlet of the convection flue is connected with the tail flue. According to the device, the defect that the organizing combustion effect in a short and small space of an industrial boiler is not ideal is overcome.

Description

technical field [0001] The invention relates to a device in the technical field of burners, in particular to a clean pulverized coal combustion industrial boiler device. Background technique [0002] Industrial boilers are important thermal power equipment. According to statistics, the total installed capacity of industrial boilers in use in the country was about 584,800 in 2009. my country has become the country that produces and uses the most industrial boilers in the world. The capacity of industrial boilers is generally relatively small. Most of the coal-fired industrial boilers in my country are still traditional chain grate boilers, and the fuel coal used cannot meet the quality indicators of the design requirements, so the boiler efficiency is generally low (usually between 55% and 85%), serious waste of energy; at the same time, environmental protection facilities such as dedusting and desulfurization are poor, resulting in serious air pollution. According to statist...
