Abstract

The invention discloses a multi-stage adjustable low-nitrogen gas burner suitable for coke oven gas. A rotational flow device is arranged between a secondary fuel barrel and a burner box shell; a combustion air inlet is formed in the side face of the burner box shell; a combustion air baffle is arranged at the combustion air inlet; the combustion air inlet is divided into two paths, wherein one path communicates with a center air barrel through a center air adjusting valve, and the other path communicates with the burner box shell; a gas fuel inlet is formed in the outer side of the burner boxshell; a main gas fuel adjusting baffle is arranged at the gas fuel inlet; and the gas fuel inlet is divided into three paths, wherein the first path communicates with a center fuel barrel through acenter fuel adjusting valve, the second path communicates with a primary fuel barrel through an adjusting device, and the third path communicates with the secondary fuel barrel. The burner can meet the emission standard.

Description

technical field [0001] The invention belongs to the technical field of ultra-low nitrogen clean combustion, and relates to a multi-stage nitrogen-lowering gas burner suitable for coke oven gas. 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. [0003] Gas fuel has the characteristics of high combus...
