Abstract

A method for igniting the powdered coal in boiler features that the plasma arc generated by plasma generator and the water steam are simultaneously delivered in an energy converting chamber for plasma ionizing to generate H2-O2 plasmas, and the high-energy H2-O2 plasmas are sprayed from igniter into powdered coal stream to generate flame and water, so igniting powdered coal and forming a stable burning kernel. Its apparatus is composed of igniter and the primary air and powdered coal channel.

Description

technical field

[0001] The invention relates to an ignition method and device for a pulverized coal boiler. Background technique

[0002] In a thermal power country, pulverized coal boiler is the main power generation. In the long-term operation, there is a problem that has not been solved well, that is, a large amount of fuel oil needs to be burned during the process of starting the furnace, combustion support, and stable combustion of the pulverized coal boiler. According to statistics, the value of fuel oil consumed in this area in the whole country is tens of billions of yuan every year. If coal can be used to replace this part of oil, the cost of burning coal is only 20% of that of burning oil based on the current prices of coal and oil. The benefits are very considerable.

[0003] Coal is solid and will not volatilize at room temperature. Coal-fired boilers burn pulverized coal, which is a particle with a size of about 100 mesh. Although the coal powder is very fine...
