Electric heating mechanical type micro-oil-gasification combustor

Abstract

The invention relates to an electric heating mechanical type micro-oil-gasification combustor. The electric heating mechanical type micro-oil-gasification combustor comprises a four-head spiral groove gasification device, an air distribution barrel, a combustion stabilization device, an ignition gun, a mechanical atomization oil gun, a first oil inlet pipe and a second oil inlet pipe. The mechanical atomization oil gun comprises a gun rod and a rotational flow disc spray nozzle assembly. The gun rod comprises an inlet end and an outlet end. The rotational flow disc spray nozzle assembly is arranged at the outlet end of the gun rod. The mechanical atomization oil gun further comprises a base and a heating element. The base is arranged at the inlet end of the gun rod. The heating element is fixedly connected with the base and is located in an inner cavity of the gun rod. Cold fuel oil sequentially passes through the four-head spiral groove gasification device and the second oil inlet pipe through the first oil inlet pipe, enters an inner cavity of the gun cavity, and is heated through the heating element to form hot oil gas; the hot oil gas enters the rotational flow disc spray nozzle assembly, forms hot oil mist again, and is sprayed out. At the initial ignition stage, the combustion efficiency is high, and the problems that at the low-temperature cold state initial ignition stage, an existing electric heating mechanical type micro-oil-gasification combustor is prone to oil dripping and black smoke emission are solved.

Description

technical field [0001] The invention relates to a pulverized coal burner, in particular to an electrothermomechanical micro-oil gasification burner. Background technique [0002] At present, the ignition technology with small oil gun and less oil has been widely used in boilers, with less equipment investment, high reliability and strong practicability. Micro-oil gasification ignition of pulverized coal technology is the development of small oil gun ignition technology. The combustion temperature of gasification fuel is higher, and the pyrolysis effect on coal powder is improved during ignition, which is more fuel-efficient when igniting coal powder. [0003] For the convenience of description, the "left" and "right" referred to below are consistent with the left and right directions of the drawings themselves. [0004] Electric micro-oil gasification burners mostly use oil guns to ignite, and mechanical atomization oil guns are commonly used. figure 1 Shown is a schematic...
