Abstract

The invention discloses a tiny-oil ignition device of a pulverized coal burner, and belongs to the field of burners. The tiny-oil ignition device of the pulverized coal burner is formed by mounting and connecting a round igniter channel pipe 1 which is provided with an adjusting valve 7 and is internally lined with a high-temperature fire-resistant ceramic chip 2, an igniter 4 extending the inside of the igniter channel pipe, a stretchable ignition oil gun 3 coaxial with the igniter channel pipe, a high-temperature fire-resistant ceramic bluff body 5 arranged at an outlet end of the igniter channel pipe, and the like. One end of the ignition oil gun is arranged in the igniter channel pipe in an extending way; the igniter is arranged on a pipe wall of the igniter channel pipe and is arranged in the igniter channel pipe in the extending way; the igniter is arranged near the outlet end of the ignition oil gun inside the igniter channel pipe; and the high-temperature fire-resistant ceramic bluff body is arranged at the outlet end of the igniter channel pipe. The tiny-oil ignition device provided by the invention has the advantages of reasonable science, simple structure, easiness for production and manufacture, convenience for use and good effect; the ignition oil consumption of the pulverized coal burner can be saved; and the fuel cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to an igniter for a pulverized coal burner, in particular to a micro-oil ignition device for a pulverized coal burner. Background technique [0002] The pulverized coal burner is one of the important parts of the thermal energy production device. It provides the heat source for the entire thermal energy system. Only a burner with excellent performance can ensure that the pulverized coal is quickly and evenly distributed in the combustion space, ignites in time, burns completely and provides sufficient energy as required. form a reasonable temperature field and thermal system to provide the best thermal conditions for the thermal device, so that the thermal device can fully function and achieve high-quality, high-efficiency, low-consumption long-term safe operation while meeting the needs of environmental protection. [0003] At present, there are two main ways to ignite pulverized coal burners, namely fuel oil ignition and plasma ...
