Fuel gas combustor

Abstract

The invention discloses a fuel gas combustor which comprises a fuel gas supply and combustion system, an air supply system and a control system. The fuel gas supply and combustion system comprises a fuel gas pipe and a combustion barrel, and the fuel gas pipe extends into the combustion barrel. The air supply system comprises an air passage and an air door, and the air passage is communicated with the combustion barrel. A fuel gas valve, a main combustion head and a flame stabilizing plate are sequentially connected to the fuel gas pipe along the fuel gas flowing direction, middles of the main combustion head and the flame stabilizing plate are provided with through holes, the main combustion head is provided with an air distribution hole, the flame stabilizing plate is provided with a flow guide hole, and the main combustion head, the flame stabilizing plate and the combustion barrel form a fuel gas and air mixed area and a combustion area. Since the fuel gas and air mixed area and the combustion area are formed among the main combustion head, the flame stabilizing plate and the combustion barrel, complete mixing of fuel gas and air can be guaranteed, and completeness in fuel combustion, high combustion efficiency and avoidance of detonation are achieved.

Description

Technical field [0001] The invention relates to a gas burner, in particular to a gas burner used in a boiler or heating furnace in the petroleum industry. Background technique [0002] At present, some boilers or heating furnaces used in the petroleum industry use natural gas, liquefied petroleum gas or oil well associated gas as fuel, especially when oil well associated gas is used as fuel, because the gas component of oil well associated gas is impure, existing gas is used Combustion opportunities cause insufficient combustion or deflagration, resulting in low combustion efficiency or low working stability of the boiler or heating furnace. The reason why the existing gas burners have insufficient combustion is that the fuel from the gas pipe is combusted while being mixed with the air from the air duct, which causes the problem of uneven mixing. Summary of the invention [0003] The purpose of the present invention is to provide a gas burner, which can achieve complete fuel com...

[0002] At present, some boilers or heating furnaces used in the petroleum industry use natural gas, liquefied petroleum gas or oil well associated gas as fuel, especially when using oil well associated gas as fuel, because the gas composition of oil well associated gas is impure, using existing gas The combustion opportunity will cause insufficient combustion or deflagration, resulting in low combustion efficiency or low working stability of the boiler or heating furnace

The reason why the existing gas burner has insufficient combustion is that the fuel coming out of the gas pipe burns while being mixed with the air coming out of the air duct, and there is a problem of uneven mixing
