Abstract

The invention relates to a coal-fired burner, in particular to a coal gasification pressurizing back-fire spitfire type coal-fired burner, which resolves the problem in prior art that coal combustion efficiency of coal gasification coal-fired burner is remained to be increased. The coal gasification pressurizing back-fire spitfire type coal-fired burner comprises a shell and a coal gas combustion chamber provided with a fire bar at lower portion. The invention is characterized in that a sealing chamber arranged at the lower portion of the fire bar is connected to a primary air agent air-delivery system via a primary tuyere, the top portion of the coal gas combustion chamber is connected to a pressurizing air air-delivery system via pressurizing tuyere, an outwards spitfire tuyere is arranged in the position of the burning zone, and the spitfire tuyere is connected with a secondary air air-delivery system via a secondary tuyere. The coal-fired burner is simple in structure, easy in use and low in cost, and can match with various boiler furnaces and barbecue ovens, thereby realizing clean coal combustion, improving bunker coal utilization rate and discharging pollutants measured up to environment standard strictly, and the coal-fired burner is a coal-fired burner with practical value.

Description

technical field [0001] The invention relates to a coal-fired burner, in particular to a coal gasification pressurized anti-combustion fire-injecting coal burner. Background technique [0002] At present, the commonly used coal-fired equipment is directly burned to do work, but the pollutant emissions of direct combustion are harmful and low in efficiency. Unable to ignite when the fire is broken, and unstable conditions such as too lean gas mixture limit its vigorous promotion. [0003] Chinese patent 200420065040 discloses a coal gasification coal-fired burner, which includes the lower ash collection chamber, the furnace wall and its gasification chamber, the grate between the ash collection chamber and the gasification chamber, and the primary air intake below the grate The chamber, the upper combustion port and the ventilation system form a secondary air preheating chamber between the furnace wall and the jacket. There is a secondary air inlet in the lower part of the se...
