wet back gas fired boiler for sale
"Coal to gas" birth wet back fired boiler for sale gas demand "from coal to gas" is one of the primary means to reduce air pollutant emissions. China's industrial coal-fired boilers, mostly without washing of coal, higher emission levels, the contribution of urban air pollution by up to 45% -65%. "Coal gas" will be replaced by coal-fired boiler, gas-fired, can significantly reduce emissions. In 2012, a number of ministries such as Ministry of Environmental Protection issued a document repeatedly requested the transformation of emissions large boiler products, such as "air pollution control in key areas" Twelfth Five-Year Plan "key projects" in the requirements, completed 2015 2841 clean energy transformation station over coal-fired boilers, which made it clear 465 coal-fired boilers replaced by a natural gas boiler. Since 2012, Beijing, Shanghai, Shijiazhuang, Lanzhou, and other places have been put forward more detailed policy requiring replace coal-fired boilers to natural gas boilers. Research shows that "coal to gas," the economy is weak, the policy is the main driving force. Due to higher gas prices, "to burn" after higher operating costs, such as coal-fired boiler and a full set of environmental protection equipment total annual cost of 661,900 yuan / (t / h), "coal to gas," the total cost of the annual 844,300 yuan / (t / h). Although a single coal-fired boilers to burn the economy is not strong, but mostly coal-fired boilers into a large gas-fired boiler feasible. Policy is the main driving force to promote the "coal to gas." It is understood that the gas boiler is facing 80 billion market demand, industrial boilers for the heavy head. According to "energy development" five "plan", "Boiler Air Pollutants Emission Standards", estimates derived gas boiler market space "Twelfth Five-Year" period about 800 million yuan, of which the industrial gas boilers for the heavy head, the market is 60 billion yuan; large gas power plant waste heat boiler to invest 150-180 billion yuan, natural gas distributed generation waste heat boiler to invest 50-60 billion yuan. According to "Natural gas development," second five "plan", 2015, China's natural gas supply of about 269.5 billion cubic meters. The demand side, China's gas power plant in 2015, distributed projects, industrial boilers totaling nearly 100 billion cubic meters of natural gas. By then sufficient air supply without worrying about gas shortage.
? First: to improve fuel will be coal into gas in principle, more in line with the standard requirements of the relevant countries, fueled by coal wet back fired boiler for sale has been subject to strict national authorities to stop, that there is often a boiler in the enterprise will fired boiler into gas boiler rehabilitation programs embodiments, may use natural gas or alcohol as a fuel after passing through this transformation, the raw coal to reduce all kinds of pollution caused by the fuel, thus using not only environmentally friendly but also improvement in the fuel cost. Second: the furnace to improve coal-fired boiler furnace into a gas furnace is the use of coal-fired auxiliary boiler for heating the furnace, and then to improve the use of gas for heating, if not exactly when or poor fuel atomization in the combustion gas gathering hearth or tail, it is very prone to catch fire or explode, so then you need to hearth to improve device blast doors, while adding automation and control ignition and flame failure protection devices to ensure safe operation of the furnace process. Third: When ancillary equipment prior to improvement has not improved during the coal-fired furnace operation requires a lot of ancillary equipment to carry out normal operations, ancillary equipment commonly used in general including the coal, Cleaner, dust collector and grate, etc. followed by boiler using these accessory devices do not need to use a gas stove, so you can save and invest more of boiler equipment. Fourth: to improve the degree of environmental protection we all know has been a coal-fired furnace is not allowed by the national environmental policy, coal is a serious source of pollution not only pollutes the environment but also cause a variety of effects on the body, adopted after performing boiler gas furnace and greatly reduce emissions of soot and various dust can effectively improve air quality, more environmentally better protect the cleanliness of the air, but also more in line with national standards of environment protection and energy policy.
After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, and gas-fired attention and widely used, broke the burning coal wet back fired boiler for sale "thriving" situation. With respect to polluting coal-fired boilers and oil-fired boilers, gas boilers use of clean energy - natural gas, less pollutant emissions, higher energy efficiency, in general, more cost-effective. Here follow the fast boiler together to understand the pros and cons of specific natural gas boiler it.
Cooperation with the fast wet back fired boiler for sale really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
