Abstract

An embodiment of the invention provides a vertical type pulverized coal boiler. The vertical type pulverized coal boiler comprises a combustion chamber and a shaft flue, wherein the shaft flue is closely against the water wall of the combustion chamber. The vertical type pulverized coal boiler is simple in structure and good in sealing performance.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a vertical pulverized coal boiler. Background technique [0002] my country's energy resources are characterized by rich coal, lack of oil, and little gas. This means that coal will dominate my country's energy structure at present and for a long time to come. However, the current situation of coal-fired industrial boilers in China is not optimistic. [0003] One is serious pollution. Data show that in 2010, coal-fired industrial boilers in China emitted about 10 million tons of sulfur dioxide, about 2 million tons of nitrogen oxides, about 1 million tons of dust, and about 90 million tons of waste residue, which is the second largest in my country after coal-fired power generation. Soot type pollution source. However, among the industrial boilers in China, more than 85% of the total number and total capacity are coal-fired industrial boilers. [0004] The second is the low l...
