Abstract

The invention relates to a combustion machine, in particular to a gas-solid dual-fuel low-nitrogen combustion machine. The gas-solid dual-fuel low-nitrogen combustion machine solves the problems that an existing combustor for a boiler is insufficient in combustion, gas combustion and mixing control are insufficient, and the combustion efficiency is influenced. The gas-solid dual-fuel low-nitrogen combustion machine comprises a dual-fuel hot water boiler, a dual-fuel left combustion device, an igniter, an ignition nozzle, a braize conveying pipe, a combustion air blower and a natural gas transportation pipe; and the dual-fuel left combustion device is connected with the dual-fuel hot water boiler; the braize conveying pipe and the natural gas transportation pipe are both connected with the dual-fuel left combustion device, and the igniter is installed in the ignition nozzle. The gas-solid dual-fuel low-nitrogen combustion machine belongs to the field of boilers.

Description

technical field [0001] The invention relates to a burner, in particular to a gas-solid double-fired bottom single burner, which belongs to the field of boilers. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way, and is mainly used on boilers. The existing boiler burner has insufficient fuel combustion and insufficient mixing of gas and control, which affects the combustion efficiency. Contents of the invention [0003] In order to solve the problem of insufficient fuel combustion and insufficient mixing of gas and control in the existing boiler burner, the present invention further proposes a gas-solid double-fired bottom single burner. [0004] The technical scheme adopted by the present invention to solve the above-mentioned problems is: the present invention includes a dual-fuel hot water boiler, a dual-fuel left burner, an igniter, an ignition burner, a pulverized coal delivery pipeline...
