Research And Application Of Micro Oil Ignition Technology In 200MW Unit

Power plant has been is petroleum resources guzzler, per million KW unit in oil about 1500 tons, with the increase of the power plant installed capacity, coal-fired unit fuel consumption also increased year by year. The start of the conventional pulverized coal boiler of power station now, ignites the fuel oil, oil in furnace combustion for a period of time, the temperature rises to the pulverized coal ignition temperature, usually according to the provisions of the rules of operation requirements of boiler load at around 15% and 20%, the temperature at the exit of furnace reached 580 DEG C, and powder feeding, of oil and coal mixed combustion, until the coal stable combustion and off the oil, complete ignition start-up process. Once the load is reduced, combustion instability, and then into the gun for stable combustion. At present, China’s power industry annual oil consumption has reached 16 million tons, of which power plant boiler Kai stop fuel consumption accounts for 60%, low load stable combustion accounted for 40% of the fuel consumption. As a result of the high price of oil, the fuel cost of starting ignition and low load stable combustion is a great influence on the economic benefits of power generation enterprises. Oil visible power enterprises, not only can reduce the cost and increase the benefit, but also related to national energy security. In the face of this grim situation, the research and development of pulverized coal ignition, ignition and combustion of fuel reduction has important significance.Based on the research of #4 unit in Fengzhen power plant, this paper studied the technology of the oil burner and the installation process, and how to operate and maintain the micro oil ignition technology in Fengzhen power plant; This paper has certain reference value for the 200 MW coal generating unit to have a certain reference value for the micro oil reconstruction project.
