    锅炉突然熄灭怎么?
    来源:http://www.jnlzsb.com 发布时间:2021-01-06

    燃气锅炉包括燃气燃烧设备和锅炉本体两个系统。燃气燃烧设备主要指炉膛和燃烧器, 也包括其他与燃烧过程有关的设备, 它的主要作用是将一部分数量的可燃气体和空气通入燃烧设备中, 通过可燃气体的燃烧将化学能转变为热能,给锅炉本体提供持续的热能。燃气锅炉作为一种产生热能和动力的工艺设备,广泛地应用于电力、机械、化工、纺织及造纸等工业部门及宾馆、居民区采暖供热等方面。燃气锅炉已经逐步进入人们生活的周围。
    Gas fired boiler includes two systems: gas burning equipment and boiler body. Gas combustion equipment mainly refers to the furnace and burner, also including other equipment related to the combustion process. Its main function is to pass a part of combustible gas and air into the combustion equipment. Through the combustion of combustible gas, the chemical energy will be converted into heat energy to provide continuous heat energy for the boiler body. As a kind of process equipment to generate heat and power, gas-fired boiler is widely used in electric power, machinery, chemical industry, textile and paper industry, hotels and residential areas. Gas fired boiler has gradually entered people's life.
    燃气锅炉在正常运行中, 有时会产生突然熄灭的现象。
    In the normal operation of gas-fired boiler, sometimes it will produce the phenomenon of sudden extinction.
    1. 燃气锅炉熄火的现象
    1. Flameout of gas-fired boiler
    (1) 炉膛负压突然增大 。
    (1) The negative pressure of furnace increases suddenly.
    (2) 炉膛内变暗, 由看火孔看不到火焰。
    (2) The furnace is darkened and no flame can be seen from the fire hole.
    (3) 汽压、汽温下降。
    (3) The steam pressure and temperature decrease.

    2. 燃气锅炉熄火的原因
    2. Causes of gas boiler flameout
    (1) 气中带杂质水过多 。
    (1) There is too much impurity water in the gas.
    (2) 机械杂质或结焦, 造成燃烧器堵塞。
    (2) Mechanical impurities or coking cause burner blockage.
    (3) 供气阀门故障或误动作造成来气中断 。
    (3) Air supply valve failure or misoperation causes interruption of incoming air.
    (4) 气压过低,中断供气。
    (4) The air pressure is too low and the air supply is interrupted.
    (5) 过滤网或气管堵塞, 阀芯脱落堵塞气路,稳压阀上的通风口堵塞, 致使气压下降。
    (5) The filter screen or air pipe is blocked, the valve core falls off and the air path is blocked, and the vent on the pressure stabilizing valve is blocked, resulting in the decrease of air pressure.
    (6) 配风不当,风量过大将火吹熄。
    (6) Improper air distribution and excessive air volume will blow out the fire.
    (7) 水位过低,保护动作。
    (7) If the water level is too low, the protection will act.
    (8) 电磁阀故障。
    (8) The solenoid valve is faulty.
    3. 燃气锅炉熄火的处理
    3. Treatment of gas boiler flameout
    (1) 关闭锅炉总气阀及各运行喷嘴的分气阀。
    (1) Close the main gas valve of the boiler and the distributor valve of each operating nozzle.
    (2) 保持锅炉正常水位 。
    (2) Maintain the normal water level of the boiler.
    (3) 查明原因和故障后重新点火。
    (3) Find out the cause and remove the fault before ignition again.
