A method of manufacturing a fuel gasification burner

Abstract

The invention discloses a manufacturing method of a fuel oil gasification combustor. The combustor comprises an inner drum and an outer drum surrounding the inner drum, wherein the axis of the inner drum and the axis of the outer drum are parallel or overlapped, a sintered powder metallurgical body is arranged between the inner drum and the outer drum, holes are formed among metallurgical powder particles of the sintered powder metallurgical body, and a preheating body is arranged in the sintered powder metallurgical body, adopts an electric heating manner and is connected with an external power supply of the fuel oil gasification combustor. The heating efficiency of the preheating body for the fuel oil gasification combustor is improved, and meanwhile, the assembly cost is reduced. The manufacturing method comprises steps as follows: a, the outer drum is arranged to surround the inner drum, and the axis of the outer drum and the axis of the inner drum are parallel or overlapped; b, the preheating body is arranged in the corresponding position between the outer drum and the inner drum; c, the part requiring a reserved gap is filled with a filling body having the corresponding reserved gap shape; d, the gap between the outer drum and the inner drum is filled with metallurgical powder, and the holes are formed among the metallurgical powder particles; e, the metallurgical powder between the outer drum and the inner drum is sintered.

Description

technical field [0001] The invention relates to a method for manufacturing a boiler ignition device, in particular to a method for manufacturing an ignition device that uses fuel oil as fuel for combustion. Background technique [0002] At present, oil gun burners are often used on coal-fired generating sets in thermal power plants, but the oil gun burners have the problem that the fuel flow can be adjusted in a small range. In order to increase the adjustable range of burner fuel flow, many new burner technologies have been developed. [0003] The Chinese patent application with the application number 200610042595.2 discloses a burner comprising a fuel oil gasification body, and a powder metallurgy with micropores is arranged on the fuel passage of the gasification body (corresponding to the fuel oil gasification burner in the present invention). body, which can make the fuel oil be refined into oil mist after passing through the powder metallurgy body; even when the press...
