Ultra-low-nitrogen gas combustor with gun head self-combustion-stabilization devices

Abstract

The invention discloses an ultra-low-nitrogen gas combustor with gun head self-combustion-stabilization devices. The ultra-low-nitrogen gas burner comprises a combustor box shell, an inner central air barrel, a central fuel barrel, an outer central air barrel, a rotational-flow air barrel and a plurality of gas fuel spray guns, wherein the inner central air barrel, the central fuel barrel, the outer central air barrel, the rotational-flow air barrel and the combustor box shell are sequentially arranged from the inside to outside; and an annular gas collection box is arranged at the outer side of the combustor box shell, a trace fuel gun provided with a windproof cover or a flame stabilization disc is arranged on the side surface of a gun head of each gas fuel spray gun, a first fuel gas outlet is formed in the top of each trace fuel gun, a plurality of second fuel gas outlets are formed in the side surface of the top of the trace fuel gun, and the corresponding flame stabilization disc or windproof cover is arranged on the side surface of the top of the trace fuel gun. The combustor is stable in combustion, and has the characteristics of being high in combustion efficiency, low in nitrogen oxide emission, low in cost and simple in structure.

Description

technical field

[0001] The invention belongs to the technical field of ultra-low nitrogen clean combustion, and relates to an ultra-low nitrogen gas burner with a gun head self-stabilizing combustion device. Background technique

[0002] In recent years, the demand and price of energy have been rising, while the supply of energy is relatively tight, and the problem of energy gap has become more and more obvious. At the same time, global environmental problems have become increasingly prominent, such as climate warming, acid rain and photochemical smog. Attention, at present, the world's energy supply mainly depends on fossil energy, and combustion is the main way of its energy conversion, which converts the chemical energy of the fuel into heat energy, and the energy obtained by burning fossil fuels accounts for more than 90% of the world's total energy consumption. The task of energy conservation and emission reduction is arduous.
