A blast furnace gas power generation combustion equipment

Abstract

The invention discloses a combustion equipment for blast furnace gas power generation. The top of the equipment body is provided with a combustion tank, the inner side of the combustion tank is provided with an interlayer, the top of the left side of the interlayer is installed with a smoke pipe, and the bottom end of the smoke pipe is installed with a filter. The bottom of the tank is provided with a combustion chamber, the bottom of the combustion chamber is provided with a gas mixing chamber, the middle of the bottom of the gas mixing chamber is provided with a gas inlet, the two sides of the gas inlet are provided with combustion-supporting air inlets, and the two sides of the middle of the combustion chamber are installed with points Firearm, the top of the combustion chamber is provided with a steam chamber, the top of the left side of the steam chamber is provided with a water replenishment port, the top of the steam chamber is provided with a return port, the top of the steam chamber is provided with a steam outlet, and the bottom of the combustion tank is provided with feet. The overall structure of the gas mixing chamber of the present invention is designed as a rounded table, and the volume gradually increases from bottom to top, which can increase the intake volume of the mixed gas, ensure sufficient gas supply, and improve the quickness of ignition of the igniter.

Description

technical field [0001] The invention relates to the technical field of ironmaking, in particular to a blast furnace gas power generation combustion equipment. Background technique [0002] Blast furnace gas is a by-product combustible gas in the blast furnace ironmaking process. Its main components are CO, CO2, N2, H2, CH4, etc. If it is discharged directly without treatment, it will not only pollute the environment, but also cause a waste of resources. To improve the utilization rate of resources, in response to the national call for energy conservation and emission reduction, many iron and steel plants have begun to use combustion equipment to generate electricity from blast furnace gas. long, low power generation, and high production costs. In addition, most combustion equipment does not utilize and process the flue gas generated by combustion. For example, the blast furnace gas power generation device with the publication number CN104420905A not only has poor energy-savi...

In addition, most combustion equipment does not utilize and process the flue gas generated by combustion. For example, the blast furnace gas power generation device with the publication number CN104420905A not only has poor energy-saving effect, but also easily causes secondary pollution. secondary pollution
