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 is rotated by the swirling flow of the swirler at the nozzle of the low-quality gas nozzle (6), and mixed 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 (27) in the blunt body and porous medium body assembly (16), or can be mixed through the blunt body (27) The low-quality gas stream is diffused and mixed. Low-quality gas and combustion-supporting air will further mix in the s...

The invention discloses a low-quality gas burner, and belongs to the technical field of boiler burners. The low-quality gas burner comprises an air distribution elbow (8), a burner outer barrel (13), a gas spraying pipe (6), a positioning system of the gas spraying pipe (6), supporting parts (12), a swirler (14), and a bluff body and multihole medium body assembly (16), wherein combustion-supporting air rotates after passing through the air distribution elbow (8), the swirler (14) and the burner outer barrel (13), and enters the area of the bluff body and multihole medium assembly after mixed with low-quality gas to be further mixed and combusted; and connecting flanges (15) between the burner outer barrel (13) and a hearth of a boiler or other combustion energy equipment can adjust the length of the section, extending into the hearth, of the burner outer barrel (13) according to requirements. According to the low-quality gas burner, the problem that in the prior art, the temperature of the flue gas in the hearth is too low under the conditions of heat dissipation and low load of the boiler hearth, so normal and stable combustion of the low-quality gas in the burner cannot be guaranteed is solved.
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...
