WNS series condensing gas boiler, which is very energy-saving effect is prominent feature of saving two devices arranged on the boiler, are ND steel, energy-saving effect, low exhaust gas temperature employed.
What are the gas-fired boiler valve instrument, have any effect: In recent years, with the strengthening of China's environmental protection efforts, high low emissions, efforts to clean gas boiler gradually become the mainstream products on the market. However, to get gas boilers to maintain normal operation, there is more than boiler, but also supporting auxiliary equipment and instrumentation valves. Among them, the instrument is a major control the operating parameters of the boiler accessories, is very important.
A thermal output of up to 38 MW is possible from a single large plant CFB boiler, which corresponds approximately to the power of 500 average VW Golf cars. Up to five CFB boilers can be combined economically. A CFB boiler of this type, filled with water and ready for function, can weigh as much as 165 tons,which corresponds to the weight of 120 VW Golfs.
Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.
Article XVI: prohibits a planned urban area built or expanded cement, coal chemical, coal-fired thermal power, coking, metallurgy, ceramics and other serious air pollution industrial projects.
Article 24: Prohibition by waste-water treatment, tampering or falsification of monitoring data, in order to avoid on-site inspection for the purpose of the temporary shutdown, open the emergency discharge channel non-emergency situations, abnormal operation of pollution control facilities and other atmospheric discharge atmospheric way to avoid regulation contaminants.
Article 39: It should be the overall planning of urban construction, coal-fired heating in the region, promoting cogeneration and district heating. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired heating boilers have been built coal-fired heating boilers can not discharge standards, should be demolished within the prescribed period the city government.
Shall manufacture, import, sale and use do not meet environmental standards or requirements of the boiler.
41: partial restriction sulfur, high ash coal mining, mining prohibition radioactive and arsenic and other toxic substances than standard coal.
