High-efficiency, energy-saving and environment-friendly pre-combustion burner

Abstract

The invention discloses an efficient energy-saving environment-friendly pre-burning burner which is simple in structure, higher in heat burning rate of fuel and more energy-saving and environment-friendly. The efficient energy-saving environment-friendly pre-burning burner comprises a pre-burner, an igniter, an air inlet pipe and at least one fuel jetting device, wherein the air inlet pipe and the at least one fuel jetting device are communicated with the pre-burner; and the pre-burner comprises a pre-burning chamber and an air spraying chamber which are communicated, the pre-burning chamber is communicated with all fuel jetting devices and the air inlet pipe, the right end of the air spraying chamber is opened, the air spraying chamber is in a step shape, and the left end of the air spraying chamber is a large end. The ignition end of the igniter is located in the pre-burner, each fuel jetting device comprises a fuel spraying nozzle and an oil supply pipe, each fuel spraying nozzle is located on the side wall of the pre-burner, the fuel spraying nozzles are arranged in the pre-burner, and the left end of each fuel spraying nozzle is communicated with the corresponding oil supply pipe. The efficient energy-saving environment-friendly pre-burning burner further comprises an air blower, a vent pipe and an air bin, the vent pipe is communicated between the air blower and the air bin, the vent pipe is communicated between the air bin and the pre-burner, and the air bin is arranged on the outer wall of the pre-burner.

Description

technical field [0001] The invention relates to a pre-combustor, in particular to a high-efficiency, energy-saving and environment-friendly pre-combustion burner with simple structure, higher thermal combustion rate of fuel oil, and more energy saving and environmental protection. Background technique [0002] In recent years, haze weather, acid rain and dust pollution have seriously affected people's daily life and health. Due to the particularity of my country's energy structure, my country's industrial boilers are mainly coal-fired, and industrial coal-fired boilers are the main source of smog. How to efficiently use resources and minimize pollution has become an urgent task before us. As a clean fuel, natural gas has gradually replaced coal in urban industry due to its good environmental protection and energy saving effects. However, the current industrial boilers using gas burners are open burners, and the technology still has the phenomenon of insufficient fuel combu...

AI Technical Summary

Problems solved by technology

However, the current industrial boilers using gas burners are open burners, and the technology still has the phenomenon of insufficient fuel combustion and fuel waste due to uneven air-fuel ratio distribution, and also increases the emission of harmful substances in the flue gas.
