Touch type baffling feeding door device for combustion boiler

Abstract

The invention belongs to the technical field of combustor feeding devices and particularly relates to a touch type baffling feeding door device for a combustion boiler. A hearth preheating cabin is arranged at the lower end of the combustion boiler; the upper end of the left side of the hearth preheating cabin is connected with a baffling door through a revolving door spindle; a straw fuel slug isarranged on the left side of the baffling door; the left side of the straw fuel slug is connected with a material pushing trolley; the material pushing trolley is connected with a transmission chainon one side through a connecting clamping plate; and the transmission chain forms a lap of rotary rail through cooperation of a material pushing reduction box and a driven gear. The touch type baffling feeding door device can stop the air inlet quantity during the feeding process, so that content of nitric oxide is controlled, burning flame is isolated from the external world, and the flame outward combustion probability is lowered; the feeding automation degree is high and the failure rate is low; and the gravity is utilized to recover the perpendicularity of the baffling door to realize theclosing purpose.

Description

technical field [0001] The invention belongs to the technical field of burner feeding devices, in particular to a touch-type barrier feeding door device for a combustion boiler. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water b...

Problems solved by technology

[0003] However, traditional boilers generally use manual feeding, which takes a long time, and the boiler inlet door is easy to suck a lot of air. The nitrogen in the air will increase the nitrogen oxide content of the boiler, and it is easy to cause the combustion flame in the boiler to burn outwards. , causing danger
