300MW Coal Fired Generating Units Of Oil Saving Technology Research And Application

At present, the thermal power plant fuel saving ignition method is mainly using coal instead of oil, the main plasma ignition and micro oil ignition technology in coal instead of oil in the boiler start-up initial stage, the furnace temperature is low. And pulverized coal combustion stability is divided into the stage, stage of combustion, burnout stage, the ignition stage need very high temperature. In order to meet the ignition temperature, the traditional boiler start, need to invest a lot of oil, light diesel oil, improve the furnace temperature, then according to the procedures meet the input coal into coal oil gun. I plant using coal instead of oil saving ignition technology is the use of pre oil investment, the furnace temperature of heating to a Rules into the initial starting conditions determined in advance to start coal grinding machine with high volatile coal to replace diesel burning torch into the furnace, which can be achieved in the boiler ignition of pulverized coal to coal oil boiler startup. In normal operation, the coal grinding machine to start the optimization, the adjacent mill spray gas igniting and reached no oil mill. In this paper, we mainly study: first, start the process analysis and optimization, second, pulverizing system rules analysis and optimization, technology optimization. Through the unit start-up and daily operation process in the regulation process optimization analysis, find out how to reduce fuel usage. Start, in order to solve the problem of coal Oil, combustion stability, boiler overheating, coal oil, oil free and grinding conditions, etc., to improve the economic indicators. For the 300 MW unit to start the process of coal oil, and the daily oil free and grinding method research, reduce the use of fuel in the actual work, to achieve the main purpose of saving resources.
