降低燃用贫煤锅炉启动用油的措施

Measures for reducing startup fuel oil consumption of lean coal-fired boiler

针对燃用贫煤锅炉启动油耗高的问题,某发电公司进行了纯氧点火改造并采取了"除氧器至启动分离器循环加热"启动方式,显著降低了机组启动燃油,1年即可收回改造投资,经济效益良好。

Aiming at high consumption of fuel oil for startup of lean coal-fired boiler,the pure oxygen ignition system of a power generation company was reformed,and a startup mode 'recurrently heating from deaerator to start-up flash tank'was adopted. The startup fuel oil consumption of the unit was reduced obviously. The better economic benefit was obtained,and the cost of the reformation can be recovered for a year.
