WNS Horizontal Gas Boiler Price
How fuel (gas) wns horizontal boiler price stack height standards should be implemented as specified? Oil, gas boiler chimney of not less than 8 meters, the height of the boiler chimney by specific approval of environmental impact assessment documents OK. When there is a building within a radius of 200m from the new boiler room around the chimney, the chimney should be higher than the tallest building in more than 3m. "Boiler air pollutant emission standards" -GB13271-2014
"Coal to gas" birth wns horizontal boiler price 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.
Boilers which are several general, in what is now the mainstream Why? 1, gas wns horizontal boiler price advantages: efficient, clean, environmentally friendly, without manual operation, only need to monitor, small footprint, no transportation fuel, no need to deal with soot, due to the combustion of natural gas free of impurities, without corrosion damage to the boiler and related accessories long boiler life, defined as 15 years, but basically long-term use. Is now mainstream boiler, natural gas is the environmental protection sector, the government vigorously promoted. Cons: You do not know how much that gas prices are calculated according to the calorific value and thermal efficiency, generally bituminous coal per ton of coal (according to 5500 kcal / kg) is approximately equal to 350 to 400 cubic meters of gas. Probably a little slightly more expensive than coal. (No transport, area, ash handling, labor, etc. into the calculation). 2, oil-fired boiler, advantages: substantially the same structure and properties of gas boilers. Disadvantages: higher cost of natural gas is 2 times the boiler, diesel transportation, storage more dangerous, accident-prone. And the domestic diesel supply is unstable, easily interrupted. 3, coal-fired boilers, the advantages: the economy. Disadvantages: 1, requires a lot of ash and coal yard area. 2, a boiler fireman for 4 to 8 people. 3, boiler room and coal yard is very dirty. 4, noise, emissions of dust, nuisance. 5, environmental protection departments often to check an inattentive, he was diagnosed with excessive emissions, maintenance shutdown, fine, very troublesome. 6, coal sulfur content are more severe corrosion of boiler, 10 to 15 years after the basic unusable. Summary: Due to high oil prices and supply unstable now, and now oil-fired boiler has been temporarily withdrawn from the market. Natural gas prices due to regional differences are very different, although you are not sure where the price of natural gas, but natural gas in most parts of the domestic coal is relatively expensive, (only in Sichuan, northwest of cheaper natural gas). Especially large industrial boilers, more fuel, the cost difference is more obvious. Coal-fired boilers to heavy air pollution, with the country on environmental issues more and more attention, more stringent emission requirements for coal-fired boilers, a lot of urban cities, has stopped the examination and approval procedures coal-fired boilers. It is recommended that, if your organization is not large tonnage production of boilers, installation of gas boilers or better, although with a little more than fuel costs, but in the actual operation of the process, you can save a lot of things, while saving area, the environment is clean.
From March 18 to start, Lujiang County, Anhui Province north of the Market Authority on the area of internal security to carry out a special inspection of wns horizontal boiler price pressure boiler; To ensure the safe operation of this special equipment, complete elimination of security risks.
The inspection mainly troubleshoot and eliminate hidden dangers in the management and operation of the boiler links exist, focus on examination of whether to establish safety management systems and procedures; whether to set security management or part-time security management staffing; whether workers with valid work certificate for employment; boiler operating records, inspection records and shift recording is complete; if the boiler for the use of registration; whether the inspection within the validity period; check valve is within the validity period, the pressure gauge whether the test within the validity period. Up to now, law enforcement officers dispatched 27 people, focus on examination of 12 times the focus of special equipment supervision units, hospitals, schools, boiler 20 times, do not meet the specified use in accordance with the boiler "Special Equipment Safety Law of People's Republic of China." requirements, issued a supervision instructions, requires immediate rectification unit, for there is no regular inspection of boilers or unqualified, shall not be put to use.
