A gathering type gas combustion equipment for waste heat recovery

Abstract

The invention discloses convergent fuel gas combustion equipment for waste heat recycling. The equipment comprises a furnace head body, an inner flow guide barrel fixedly connected with the furnace head body and an outer heat insulation shell arranged outside the furnace head body and the inner flow guide barrel. The inner flow guide barrel is fixed to the bottom of the furnace head body, the upper end of the furnace head body is provided with a wind shied, a hearth is arranged in the wind shield, and a combustion nozzle is installed in the hearth. The top end of a spiral channel is provided with a flow guide channel, and the flow guide channel communicates with gas spray holes in the inner side of the wind shield. Air flows from bottom to top along the spiral channel, heat on the inner flow guide barrel, and the furnace head body and the outer heat insulation shell can be absorbed and reused. After gas is sprayed out of the gas spray holes, air flows in a vortex shape in the wind shield so as to be conveniently mixed with fuel gas sprayed out by the combustion nozzle and to facilitate combustion of fuel gas, combusting flame can be gathered towards the middle conveniently, the flame combusting effect is improved, and outward diffusion of heat is reduced.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, more specifically, it relates to a gathering type gas combustion equipment for waste heat recovery. Background technique [0002] There are many kinds of kitchen burning stoves, and its structure should include a furnace body, a burning stove head, a gas supply and a fuel supply system. The burner head is installed in the furnace body, and the gas supply system provides the oxygen for combustion. Under the condition of oxygen, the fuel is sprayed from the nozzle to burn in the burner head. The function of the burner head is to ensure the normal and maximum complete combustion of the fuel. The structure of the burner head includes an air supply piece, an air intake piece, a fuel nozzle and a mixing combustion chamber. There is a gap between the air supply piece and the air intake piece. In the gap, there are small round holes around the intake piece to communicate with th...

AI Technical Summary

Problems solved by technology

[0003] 1. The air and gas entering the air supply parts cannot be fully mixed, which will have a negative impact on combustion, affect the cooking quality and consume more fuel, and cause incomplete combustion of fuel, wasting fuel

2. The airflow rotated by the air supply part is a kind of turbulent gas. The turbulent gas is sprayed from the small round holes around the air intake part to the center of the combustion chamber and then interferes with each other. The atomized fuel sprayed by the nozzle may be disturbed gas , these particles may be taken out of the combustion chamber by the airflow into the furnace or even outside the furnace to continue burning, which will affect the complete combustion of fuel and cause fire hazards
