waste heat recovery boiler snap
Dongying City, Shandong Province in response to low-nitrogen coal-fired waste heat recovery boiler snaps, 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.
Condensing waste heat recovery boiler snaps must immediately solve the problems facing the current problems faced by condensing boilers must be addressed: 1, condensing boilers do not adapt to some of the high-temperature systems, suitable for low-temperature radiant floor heating. 2, condensing boilers require specially designed temperature control system and debugging equipment. 3, the condensed water generally has a slightly acidic, corrosion resistance is required ferritic stainless steel, austenitic stainless steel, aluminum and the like; 4, annual operating time equivalent assessment of investment and recovery period; 5, the condensed water and recycling emissions. 6, power can not be too small, there will backfire, causing an explosion, corrosive wall. (Recommended to choose the power of 35 kilowatts and above)
There are two main types of thermal power station waste heat recovery boiler snap: pulverized coal boiler and CFB boiler. These two types of boiler are the main types of thermal power station used at present. The biggest difference between fluidized bed furnace and pulverized coal boiler is liquid and coal powder.Thermal power plant capacity is large generally.The capacity can up to 1000MW now,but thermal power plant use 100MW-600MW is normal.
Boiler quality problem how to find better quality gas-fired waste heat recovery boiler snap is also an important issue that has to be considered in the selection process. And the solution to this problem involves roughly two steps: 1. inform the merchant of his specific needs and uses and ask him to recommend some suitable gas-fired boiler equipment. The second is to compare the technical parameters, specific operation and functional use of the boiler equipment recommended by the merchants, and then choose a more reliable gas-fired boiler from it.
