This company installed a 20 ton gas boiler to meet the heat demands of paper machine. Heat is a vital part of every pulp and paper production process and therefore a constant heat supply is essential for the mill to remain competitive.
Dongying City, Shandong Province in response to low-nitrogen coal-fired boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.
Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.
After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.
Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.
According to statistics, this year the city of Dongying city plans to add a total area of clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.
Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.
