A combustion device that adjusts the use of nozzles by itself

Abstract

The invention discloses a combustion device used for a self-adjusting nozzle. The combustion device comprises a burner shell, a combustion casing connected with the burner shell by bolts and an exhaust pipe installed on the burner shell. A fixing seat is connected to the bottom end of the burner shell by locking nails, and a gas input duct is fixed inside the fixing seat. A gas delivery outlet isformed in the top end of the gas input duct, and the gas delivery outlet communicates with a gas mixing cavity. The gas mixing cavity is formed in the exhaust pipe, and a plurality of flow guiding holes is formed in the side wall of the exhaust pipe. The flow guiding holes communicate with an air cavity, combustion nozzles are formed in the upper side wall of the exhaust pipe, and a sealing plug is arranged at the top end of the exhaust pipe. The input and fully mixing of gas and air into the gas mixing cavity are facilitated. After the mixed gas is ejected, the igniter ignites for combustion,and the combustion casing guides the flame to increase the heat coverage. According to the different air pressure, the ejected length of the sealing plug is different, so that the number of the combustion nozzles used on the exhaust pipe is self-adjusted according to the air pressure.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, and more specifically, it relates to a combustion device for self-adjusting the use of nozzles. 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 the mi...

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
