Problems solved by technology

The problem with the original gas stove is that it can only produce gas and does not have the function of blowing fire.
Gas is prone to heat loss, flammability, explosion and poisoning during transportation; the combustion efficiency of coal in the gasification layer is not high, resulting in high energy consumption

Embodiment Construction

[0018] figure 1 It is the best embodiment of the present invention, which is described below in conjunction with the accompanying drawings of the embodiment.

[0019] The built-in combustion moving bed gas furnace has a coal conveying mechanism at the lower part of the furnace body. The furnace at the upper part of the furnace body is a gasification layer. On the flame outlet (the flame outlet can be at any position above the furnace), a combustion burner 4 is set, and an air distributor 5 is arranged in the furnace body at the bottom of the gasification layer. The furnace body is provided with a refractory material 1 insulation masonry, and an air channel 15 is arranged in the refractory material masonry on the upper part of the furnace body. One side is connected to the fan 14, and the other side is connected to the combustion burner 4. The air provided by the fan 14 is sent into the air distributor 5 in the furnace by the furnace bottom through the air pipe 13 . The secon...

Abstract

The invention provides a gas stove with a built-in combustion moving bed, which comprises a stove body. The gas stove is characterized in that a coal conveying mechanism which conveys coal from bottom to top is arranged on the lower part of the stove body; a furnace on the upper part of the stove body is a gasification layer; the stove body above the furnace is provided with a flame outlet and a dreg outlet respectively; the coal conveying mechanism comprises a coal conveyor and a spiral material rotary move-up mechanism; and the flame outlet of the stove body is provided with a combustion nozzle. The gas stove has simple and compact structure, small equipment investment and safe and reliable operation, moves the gasification reaction layer of the prior gas stove upwards to the upper part of the gas stove to accelerate the gasification reaction of coal and further improve the temperature of a pyrolytic reaction, and ensures that mixed gas generated by the gasification layer instantly enters the built-in combustion nozzle to react with oxygen, and gas temperature after nozzle combustion can reach 1,400 to 1,500 DEG C. The mode particularly meets the requirement of high temperature heating process.

Description

technical field [0001] The invention belongs to the field of gas stoves, in particular to a built-in combustion moving bed gas stove. Background technique [0002] The gasification layer of the original gas furnace is generally located at the lower part of the furnace body, and the gas generated after coal gasification is transported to the burner through pipelines to burn to generate flame and heat. The problem with the original gas stove is that it can only produce gas and does not have the function of blowing fire. Gas is prone to heat loss and flammable, explosive and poisonous during the transportation process; the combustion efficiency of coal in the gasification layer is not high, resulting in high energy consumption. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a built-in combustion moving bed gas furnace, which can increase the coal pyrolysis reaction temperature and improve the heat utilization effi...
