Combustor box body device with stepping air mixing function

Abstract

The invention discloses a combustor box body device with the stepping air mixing function. A combustor box body is a square sealing box body. A three-section partition box is fixedly installed inside the square sealing box body, wherein the three-section partition box is provided with a first vertical plate and a second vertical plate both of which divide the square sealing box body into three independent spaces. An air mixing device is arranged between the two vertical plates, the minor diameter end of the air mixing device penetrates out of the first vertical plate, the major diameter end of the air mixing device penetrates out of the second vertical plate, the air mixing device is connected with a gas pipe, first stepped air inlets are formed in the side wall, opposite to the first vertical plate, of the square sealing box body, second stepped air inlets are distributed in the first vertical plate, an air supplement port is formed in the minor diameter section of the air mixing device, third stepped air inlets are evenly formed in the stepped end face of the air mixing device along the circumference, fourth stepped air inlets are distributed in the second vertical plate, an ignition needle is arranged between the second vertical plate and the side wall of the corresponding square sealing box body, and a combusting pipe which is coaxial with the air mixing device is fixed on the square sealing box body in a welding mode. Fuel gas and the air are mixed evenly, safety is high, and the flame is long.

Description

technical field [0001] The invention relates to a burner box device which burns gas to provide a heat source and has a step-by-step air mixing function, which belongs to heating equipment. Background technique [0002] Infrared radiation heating products imitate the principle of the sun warming the earth. It burns combustible gases (natural gas, liquefied petroleum gas, etc.) directly in a closed pipeline, heats the radiant tube to a certain temperature, and generates a certain amount of infrared rays. Radiation achieves the purpose of heating. [0003] The gas mixing combustion device of traditional radiant heating products is a Venturi tube, which only relies on the Venturi tube for gas mixing. In this case, there will be a series of problems, such as: uneven gas mixing, unstable gas flow, resulting in sometimes burning flames. Deviate from the combustion pipe, which will cause partial burning and affect the effect of radiant heating and the service life of the combustion...

[0003] The gas mixing combustion device of traditional radiant heating products is a Venturi tube, which only relies on the Venturi tube for gas mixing. In this case, there will be a series of problems, such as: uneven gas mixing, unstable gas flow, resulting in sometimes burning flames. Deviate from the combustion pipe, which will cause partial burning and affect the effect of radiant heating and the service life of the combustion pipe

More importantly, only rely on the Venturi tube to mix the gas, so that the combustion flame is not long enough, which will greatly reduce the performance of the product
