Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings. The low-quality gas burner of the present invention uses air as a combustion aid. Combustion air is sent to the air distribution elbow (8) through the connecting flange (1) and the outside air inlet pipe or the blower output flange. After the reversing action of the air distribution elbow (8), the combustion air enters to the outer cylinder of the burner (13), and rotate under the swirling action of the swirler at the nozzle of the low-quality gas nozzle (6), and mix with the low-quality gas ejected from the nozzle.

[0013] Combustion-supporting air and low-quality gas can be mixed in the gap cavity between the gas nozzle (6) and the blunt body (24) in the blunt body and porous medium body assembly (16), or can be mixed by the blunt body (24) The low-quality gas stream is diffused and mixed. Low-quality gas and combustion-supporting air will further mix in the space b...

Abstract

The invention discloses a low-quality gas burner, which belongs to the technical field of boiler burners and comprises an air distribution elbow (8), a burner outer cylinder (13), a gas nozzle (6) and its positioning system, and a support (12), cyclone (14), blunt body and porous medium body assembly (16). The combustion-supporting air rotates through the air distribution elbow (9), the swirler (14), and the outer cylinder of the burner (13), mixes with the low-quality gas, and enters the blunt body and the porous medium body assembly (16) for further combustion. Mix and burn. The connecting flange (15) between the outer cylinder of the burner (13) and the furnace of boilers or other energy-consuming equipment for combustion can adjust the length of the outer cylinder of the burner (13) extending into the furnace as required. The invention solves the problem in the prior art that the flue gas temperature in the furnace is too low under the condition of heat dissipation in the boiler furnace and low load, so that the normal and stable combustion of the low-quality gas cannot be guaranteed.

Description

technical field [0001] The present invention relates to a burner, and in particular to a low-quality fuel burner for use in boilers, which has an adjustable premix chamber in the burner housing and porous holes at the outlet for enhanced ignition combustion medium body. Background technique [0002] Low-quality gas widely exists in resource mining and processing and other industrial production links. It has less combustible components and low calorific value. It is difficult to fully mix combustible components and oxidants during combustion, and it is difficult to ignite and burn out. In the actual production process, most of the low-quality gas is directly discharged. This not only causes environmental pollution, but also increases the waste of energy resources. [0003] Due to the high operating environment of industrial and civil boilers, most of them use oil and gas fueled fire tube boilers. The furnace is not only the combustion and heat release area of ​​the fuel, bu...
