Industrial boiler stoker boiler overpressure staff, treatment Water Shortage Accidents: industrial boiler stoker boiler overpressure personnel, Water Shortage Accidents treatment of industrial boiler stoker boiler overpressure personnel, processing method 1 Water Shortage Accidents, industrial boilers boiler overpressure overpressure accident is due to an accident during the actual operation of the boiler in the actual pressure value exceeds the maximum working pressure caused. Boiler overpressure accident is an accident the most common accidents. Overpressure characterization: the boiler is running, when the pressure in the boiler is too high, the air pressure will be significantly increased, exceeding the safe working pressure of the boiler, boiler safety play a proactive action; boiler overpressure alarm will issue a warning signal; steam temperature rising Wait. Common causes of boiler overpressure are: gas fault does not operate normally with gas; valve failure, equipment failure alarm; relates to a boiler because defects result buck during use, the cross-sectional area of ​​the exhaust valve is not adjusted , still use the original terms of safety valves. Processing overpressure accident. Found boiler overpressure should be reduced combustion; if the boiler safety law does not work, can take artificial exhaust, or located vent valve on the boiler open for exhaust, to adjust the pressure of the boiler; maintaining an internal boiler water level is normal, reduce oven temperature; the oven before deciding to stop or resume operation, check the cause of the boiler overpressure and damage the furnace. 2, industrial boiler water accidents occur during use of the boiler, the boiler water shortage accident was mainly due to the boiler water level below the safety level. Boiler water often leads to additional boiler superheater heating surface tubes cause deformation even wave train; mouth off or leakage; boiler wall is damaged. In the use of the boiler, the boiler water accidents can not be properly resolved, will often bring very bad consequences, causing serious damage.

Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired boilers within the city out of small coal-fired boilers remediation process. Up to now, the work has achieved initial success.

15 in the city with 20 kilowatts and above the coal-fired generating units, 13 units have ultra-low emissions; city table 292 with 20 t steam / hour or more coal-fired boilers, emission standards have reached the count 253 male , accounting for 86.64% of the proportion of the boiler with; the city built area of ​​10 steam tons / hour small coal-fired boilers 2962 units, out of a total of 29553 units, up 99.7% out of proportion, the basic completion of the national requirements out of the task.

In order to further improve air quality, improve people's living environment standards index, Changchun City by expanding the ban on burning area, improve the standard phase-out of coal-fired boilers, plans to use two years of urban 20 tons of steam / h coal-fired boiler (kiln) furnace eliminated.

By the end of 2017, the city has eliminated 20 tons of steam / hour coal-fired boilers 964 units; at the same time to speed up the central heating and (expanding) network as well as the pace of clean energy promotion, provide for the transformation of the city's coal-fired boiler control a strong guarantee.

In recent years, Changchun City, adhere to the full implementation of coal-fired boilers governance, to improve ambient air quality in Changchun City has played a positive role. 2017, good days Changchun 276 days, compared with 2013, an increase of 35 days; heavy pollution days 10 days compared to 2013, reduced by 33 days; major air pollutants respirable particulate matter (PM10) and fine particles (of PM2.5) were 78 mg / m and 46 micrograms / cubic meter, respectively, 39.5% and 37.0% decrease over 2013.

Many heating units use gas hot water boiler in the winter for heating residential or office area. Taking into account the particular winter weather, the boiler room will do a lot of heat treatment, to prevent the cracking occurs due to the cold boiler at runtime. But this is not enough, gas hot water boiler itself also have to make antifreeze treatment.
