Abstract

The present invention relates to the layered decoupling coal buring technological and mechanical layered decoupling furnace. Coal is burned in the combustion chamber to produce fume exhausted to gasifying chamber or flue and semi-coke conveyed to the mechanical grate of gasifying chamber; the coal on the semi-coke layer is ignited from the bottom, burnt in anoxic condition and gasifying pyrolyzed; NOx in the fume is reduced into N2; and after being mixed with the second draft, CO and smoke black are burnt out. The separated burning in the mechanical layered decoupling furnace produces lowered pollutant exhaust and high burning efficiency.

Description

technical field

[0001] The invention belongs to the field of raw coal combustion technology and combustion equipment, and in particular relates to a layered decoupling combustion technology and a mechanical layer that can reduce the emission of nitrogen oxides, soot and carbon monoxide from a large-load layered combustion boiler and improve the efficiency of the combustion boiler Shaped decoupled combustion furnace. Background technique

[0002] At present, my country has made a lot of progress in solving the pollution discharge of small-capacity and large-capacity industrial boilers, but there are still few combustion technologies for high-efficiency and low-pollution discharge of medium-sized mechanical floor-fired boilers with large consumption.

[0003] The traditional layer-fired industrial furnace has a simple structure, only figure 1 In the furnace part on the right (main combustion chamber), the coal-fired coal seam directly enters t...
