摘　　要：碎煤加压气化炉空气点火时先退蒸汽后通空气,这种点火方式温度交变对汽化剂混合管造成热应力损伤,汽化剂混合管使用寿命短。通过优化空气点火方法,延长了汽化剂混合管使用寿命,降低了气化炉开车过程中的能源浪费,保证了气化炉的安全稳定运行。The air ignition of the crushed coal pressurized gasifier is done by backing off the steam first and then passing the air,which results in the thermal stress damage to the vaporizer mixing tube due to the temperature alternation,and leads to the short service life of the vaporizer mixing tube.By optimizing the air ignition method,the service life of the vaporizer mixing tube is prolonged,the energy waste in the gasifier driving process is reduceed,and the safe and stable operation of the gasifier are ensured.
