气化小油枪燃烧器在1025t/h烟煤锅炉中的应用

Application of burner with small gasified oil-gun on 1025 t/h bituminous coal-fired boiler

为了节约燃煤锅炉启动、停止以及低负荷稳燃用油,降低发电成本,华电国际十里泉发电厂对1025t/h锅炉燃烧器进行了技术改造,将原有的A层4只燃烧器更换为新型的气化小油枪燃烧器。气化小油枪燃烧器将油枪和燃烧器合二为一,综合运用了小油量气化燃烧技术、煤粉多级燃烧技术和防结焦抗烧损技术。对该技术实施的技术措施与应用效果作了详细阐述。应用结果表明,作为一项新型节油技术,气化小油枪燃烧器具有显著的经济效益和环保效益,值得在烟煤锅炉中推广。

In order to save the fuel oil consumption during start-up, shut-down and combustion stabilization at low load of coal-fired boiler, the burners of Shiliquan Power Plant were retrofitted. Four burners of Layer A were replaced by the burners with small gasified oil-gun. The new burner combined oil-gun and burner so as to use the small-quantity gasified oil combustion technology, multi-stage combustion technology, anti-coking and burned-out resisting technology. The operation procedure and application effect of burners were introduced in detail. The application result shows that it is of significant economic and environment protection benefits as well as bright prospect for promotion in bituminous coal-fired boilers.
