70mw qualified brown coal hot water boiler
Industrial boiler market share rise, to the current trend of energy-saving industry, industrial boilers are mainly used in metallurgy, chemicals, coke, cement, paper, shipbuilding and other industries, mainly through heating boiler, steam production unit each to provide the required or hot water. Different transformation and power industry, industrial boilers since often small cell capacity, installed at the rear end of expensive desulphurization and denitrification apparatus is very uneconomical, so the transformation of coal will be the main alternative route, the coal gas, biomass fuels, cleaning three coal technology route, clean coal will assume the main task. By the end of 2011, the total industrial boilers reach 58.5-60 million units, of which the boiler, the capacity accounted for more than 80% of coal-fired boilers, boiler capacity is less than the number of 35 tons / hour of 96% of the total, while 10 accounting tons / hour up to 80%. Meanwhile, the average thermal efficiency of industrial boilers only 60%, 20-25% lower than in other countries. The country's industrial kilns more than 160,000, concentrated in building materials, metallurgy, chemicals and ceramics and other industries, the annual coal consumption of 300 million tons. The average heating furnace thermal efficiency of only 40%, 10-30% lower than in other countries. A wide range of large industrial boilers in China, the average capacity of small and dominated by coal. Although China's coal-fired industrial boiler design productivity gap compared with foreign small, but the actual operating efficiency of only 65%, 10% -15% lower than the advanced level. Industrial boilers with maximum downstream chemical materials and chemical products manufacturing market size, non-ferrous metal smelting and rolling processing industry, petrochemical industry market size is large, in addition, the market size paper and shipbuilding industries is relatively small, moderate growth in the cement manufacturing industry . Overall, the future of Chinese boiler market demand is still the main metallurgy, chemical and petrochemical three coking industry, and paper, cement and other industries demand is relatively weak, shipbuilding recession has not slowed. Industrial boilers, especially coal-fired industrial boilers for energy saving is important for achieving the overall goal of energy conservation.
Gas-fired steam boilers are also more convenient to use in operation, so they will be favored by users of all enterprises. All natural gas pipelines are just as convenient as tap water for domestic use, and there are no problems with sustainable use. It eliminates the cumbersome work of using coal to transport or stack and clean coal cinder.
6 tph WNS series condensing gas-fired steam boiler project for printing and dyeing industrySteam boilers provide heat source for dyeing, drying, slashing and printing in printing and dyeing industry. Nantong New Dunhuang Dyeing Co. LTD. has always been providing excellent products and after-sales service to customers for the 16 years' constant development, main business including: yarn bleaching and sales, sales of carpet and garment fabrics and decoration cloth. As the state is promoting the substitution of small gas-fired boilers, Nantong New Dunhuan decided to introduce one set of gas-fired steam boiler with sufficient output and high efficiency. A set of high-quality boiler is essential for a dyeing and printing enterprise, which can not only enhance productivity but also reduce operating costs. After some market research, Nantong New Dunhuang chose ZOZEN as their cost-effective boiler supplier. In the process of technical communication, New Dunhuang spoke highly of ZOZEN professional degree and ordered one set of 6 tph WNS series gas-fired steam boiler (WNS6-1.25-Q). This series of boilers is ZOZEN's own R&D and has good reputation in the market with excellent product performance. It has wide fuel adaptability, applicable to a wide range of fuels including natural gas, methane, coal gas, diesel, heavy oil, light oil, etc., It adopts a large-diameter corrugated furnace to ensure the completed combustion, along with a low NOx burner, the NOx emission can be controlled below 30mg/Nm3. The boiler features automatic and safe operation, can automatically adjust and protect the combustion condition, water level, temperature and steam pressure in the course of operating. ZOZEN also installed the condenser, economizer for the tail flue, which would recycle the flue gas and decrease the exhaust temperature below to 60 degrees. The thermal efficiency is as high as 98%, which is higher than the same products in the market.
Chongyang County, Hubei Province since the second half of 2015 to carry out the work out of small coal-fired boilers, non-New 20 tons of steam / hour and below the coal-fired boilers, the full implementation of small coal-fired boilers out of work, with environmental protection, Development and Reform Commission, by letter and other related sector wages, work to strengthen the efforts to promote thorough investigation of strict control to ensure that the county's non-compliance of small coal-fired boilers have all been eliminated remediation. In the specified date (June 30, 2017) completed the small coal-fired boilers out of the task before. Up to now, Chongyang County is not a new coal-fired boilers.
It is understood that, recently, joint quality supervision department of Chongyang County People's Government of Hubei Province, a special selection of personnel to carry out "looking back" activities for the phasing out small coal-fired boilers, special personnel division of responsibilities is based on special teams, focus on examination paper, under chemicals, wine, agriculture, and several other sectors and enterprises of boiler equipment, non-small coal-fired boilers happen "resurgence" phenomenon.
