how to calculate heating surface area of boiler

The advantages of condensing how to calculate heating surface area of boilers: condensing boiler gradually into the public view, but there are still a lot of people did not know much about them, to adopt a modern condensing boiler is the latest scientific research and technology - condensing boiler technology, this technology will condense the traditional boiler with separately, can increase heat boiler in a great extent, and because it is not the use of coal, has great environmental protection. Full-featured, good quality condensing boiler not only has the above characteristics, but also has some other advantages.

For the 2018-2019 autumn-winter air pollution prevention and control work, Jinhua City, Zhejiang Province issued a public draft, mainly in the autumn and winter to reduce heavy pollution weather Development frequency.

Take measures to reduce coal comprehensive, non-electric focused on reducing the total coal consumption, in 2018 the city's total coal consumption reduction of 1% compared with 2015. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption of the same amount of capacity reduction or substitution, elimination of energy consumption, water consumption, environmental protection and safety is not up to 300,000 kilowatts coal-fired units. Development of industrial parks "One District One heat source" action plan, and more than 300,000 kilowatts coal-fired units were heating transformation, promote backward and shutting down small coal-fired thermoelectric integration of coal-fired boilers in the range of 15 km radius of the heat. Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, to the new "coal to gas" projects, should adhere to increase coal gas reduction synchronized to gas will change, the premise of the gas supply contract signed and orderly implementation.

Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation to ensure that no dead ends, no blind spot. Investigation and the coal-fired boilers to register one by one.

According to the law to increase the city's efforts to phase out coal-fired boilers in accordance with regulations. Before the end of December 2018, the city basically out of 10 tons of steam per hour of coal-fired boiler, built-up areas out of 35 tons of steam per hour coal-fired boilers. Complete 1 set (Yiwu) per hour, 40 tons of steam coal-fired boilers transformation of ultra-low emissions, coal-fired plants to achieve ultra-low emission levels.

In principle, the boiler NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. New installation and reconstruction of gas-fired simultaneously supporting the low NOx combustion device.

Biomass boilers to carry out a comprehensive investigation, complete control of boiler scale, distribution, fuel, furnace, pollution control facilities and pollutant emissions, and establish a list of management accounting. Yan Gesheng biomass boiler registration, strictly control the new urban area of ​​biomass boilers. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of ​​biomass boilers ultra-low emissions transformation. For existing biomass boilers, environmental inspection carried out one by one, there are multiple distributed biomass boilers, the implementation of the demolition of small and large industrial agglomeration area.

Henan detect gas how to calculate heating surface area of boiler gas boiler basic content of Henan detection requires a planned program, do the safety testing according to different time periods. Regularly check the contents of a boiler includes external inspection, internal inspection and hydrostatic commissioning of three elements. Only three directions from start to discover a problem, the problem has been eliminated, to ensure the safe and stable operation. When gas boiler Henan external inspection, no downtime detection can be performed in a state where the normal operation of the boiler testing, inspection and make a reasonable assessment of the security status of the boiler, external examination may have a certain time interval, usually a in inspections, timely detection of problems. Henan gas when internal inspection of the boiler, in order to ensure safety, it is necessary for the boiler in a shutdown state, through the interior of the device and means for detecting the boiler, a reasonable assessment of the safety, the detection of such frequency may be every other year. Detecting water pressure debugging mainly detected Henan medium gas boiler, the boiler pressure according to well estimated using a predetermined standard, by a certain pressure member under a state of performance evaluation of the formation pressure boiler, for non-compliance good parts replacement, to ensure tight joints associated, generally once such detection may be six. Only three checks in place to ensure comprehensive, and operated within the effective period, in order to ensure safe Henan gas boiler.

180 ton CFB coal fired how to calculate heating surface area of boiler advantages:

1) It has higher burning efficiency and higher heat efficiency.

2) It can realize getting rid of sulfur inside the furnace by adding CaCO3 and the efficiency can catch up to 90% and above and this is done at low temperature which can prevent from producing NOx and is good for protecting environment.
