chinese mini industrial steam gas industrial boiler
Steam chinese mini industrial steam industrial boiler automatically displays the instrument will encounter in the use of water which asked steam boilers by fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boilers. According to the structure can be divided into vertical steam boilers, horizontal steam boiler, steam boiler small single, double back to the vertical structure, large steam boiler mostly as three-pass horizontal structure. When the water level is low or groundwater automatically display meter, installed in the steam boiler only a low level means, even water too thin; when the groundwater level automatic means or instruments show lower, the steam boiler is mounted in a water only means; e no other ground water drainage means drainage cock; drum means on a level effective means further water damage; plug door apparatus can not twist the water level; a level plug door apparatus leakage leakage; means water false water level display; water level on the two drum devices are inconsistent; water glass breakage frequently means; glass protection device is not level; water means water level glass plate red indicator is not displayed; glass plate It does not show red; red glass panel is not displayed. If the apparatus dirty water, the water level can not be clearly observed. Steam boiler water level gauge inconsistencies mainly glass and clear observation of steam boiler water level gauge is not cleaned for a long time during operation, routine maintenance is not performed, resulting in water means cocks rust, soda connecting tube blockage. Or filler inadequate or aging. In addition to steam, water or tap is blocked, the phenomenon of false water level may also be due to misalignment between the steam pipes and caused the water level instrument; steam, dislocation faucet handle position will result cocks closed, but may also be due to boiler poor water quality, and water vapor and water and the water level caused by false. Broken glass is mainly water vapor, the centerline of the tap out of alignment, the bending stress in the glass tube memory, no glass expansion gap length is too large, the water level window directly blown cold, poor quality glass. During the boiler operation, we found that the water level is unclear, when the ultra-high water level should be stopped immediately, should discover the problem.
Gas steam chinese mini industrial steam industrial boiler load changes in the water level of air pressure adjustment What happens next: load fluctuation gas steam boiler water level of the air pressure regulating what impact the boiler load refers to the amount of steam is supplied outside?. When the variation amount of steam needed outside world, boiler pressure, temperature, level crossing will move. When the load increases, the pressure drop in the water level is low, the air supply should be increased and the amount of coal. While enhanced combustion, and gradually increase the amount of water to maintain normal air pressure and water level. When reducing the load, the air pressure is high the water level rises, the amount of coal should be reduced and the air volume, reduce combustion, then the appropriate amount of water to reduce or suspend the water supply, the air pressure and water level in the stable nominal range, then press normally combustion and to adjust the amount of water. When reducing the load, the pressure rise when the water level is low, to increase the amount of water should be, until the water level returns to normal, then the need for air pressure changes and the load situation, and to adjust the combustion water.
Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired chinese mini industrial steam industrial 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.
The pharmaceutical industry is also a major market for chinese mini industrial steam industrial boiler applications, and the most used in pharmaceutical plants is steam boilers. It has been estimated that oil andgas boilers in pharmaceutical plant boilers account for nearly half of the market. Oil andgas steam boilers consume a large amount of natural gas fuel and produce high-temperature steam for high-temperature sterilization of equipment in the pharmaceutical industry, disinfection of raw materials, drying, packaging and disinfection. The steam produced by the steam boiler can be used in many places such as laboratories, research centers, production workshops, etc.
