This year, Hubei Province, will continue to carry out prevention and control of air pollution control, effectively promote the province's environmental air quality improved, and issued the "2019 Annual Hubei ecological system of air pollution prevention and control program of work", as follows.
First, ultra-low emissions and actively promote the transformation of key industries. The province's new coal-fired thermal power units fully implemented ultra-low emissions standards. Actively promote small coal-fired thermal power ultra-low emission transformation, Wuhan, Xiangyang, Yichang and other places to complete before the end of 2019. Circulating fluidized bed boiler unit to achieve ultra-low emissions before the year 2019, tobacco dust W flame boiler units, to achieve ultra-low sulfur dioxide emission limit requirements. Ultra-low emissions and actively promote the transformation of the steel industry, the whole process to reduce air pollutant emissions.
Second, the depth of key industries mentioned standard upgrade. Promote the implementation of major cities in key industries especially emission limits, strictly enforce the "Notice on the implementation of some key cities in particular air pollutants emission limits" (Provincial Environmental Protection Bureau Bulletin 2018 No. 2), advance planning to enact governance project, and accelerating coking industry desulfurization and denitrification projects. According to the national unified deployment and actively carry out industrial furnaces governance special action. Complete waste discharge permit issued in accordance with the work list management requirements.
Third, the total coal consumption in key areas to promote control. Actively cooperate with relevant departments to implement controls total coal consumption in key areas, focusing on reduction of non-coal for electricity. With the relevant departments to promote the commercial coal quality control and supervision of bulk coal sales, strengthen the management and control of coal consumption, promoting the use of clean coal.
Fourth, the optimal adjustment of high-pollution fuel combustion zone ban. Control Department of Ecology Environment "high-pollution fuel directory" to improve the demand by the City People's Government in accordance with the ambient air quality, energy consumption structure and affordability, local conditions choose ban combustion zone ban burning of the fuel mix category, supervise the implementation of the relevant control requirements. Urban cities and states to complete high-pollution fuel combustion zone ban optimal adjustment before the end of 2019.
Fifth, to carry out rectification of coal-fired boilers. Carry out coal-fired boilers out of looking back, resolutely combat the resurgence of acts of the boiler has been eliminated. The county level and above urban area actively eliminate 10 tons of steam per hour coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal-fired facilities, in principle, to a new 35 tons of steam per hour of fuel coal boiler. Actively promote the upgrading coal-fired boilers environmental protection facilities renovation and construction of facilities on-line monitoring, adherence to the "gas will change," the principle of steady progress "from coal to gas."
Circulating fluidized bed combustion(CFBC) Advantages :
1. Fluidized bed can burn a variety of fuels-coal as well other non-conventional fuels like biomass, petro-coke, coal cleaning waste and wood. This bed contains only around 5 percent coal or fuel. The rest of the bed is primarily an inert material such as ash or sand. Fluidized bed boilers are capable of burning a wide range of fuels cleanly, including biomass fuels such as wood waste.
2. The Temperature in FBC is around 800-900°C compared with 1300-1500°C in pulverized coal combustion (PCC). Low Temperature helps minimize the production of NOx (nitrogen oxides). With the addition of a sorbent into the bed (mostly limestone), much of the so2 formed can be captured. The other advantages of FBC are Compactness Ability to burn low calorific values (as low as 1,800 kcal/kg) Production of ash which is less erosive. Moreover, in FBC, oil support is needed for 20-30 percent of the load versus 40-60 percent in PCC. FBC based plants also have lower capital costs compared to PCC based plants. The capital costs could be 8-15 percent lower.
As our wood chip or wood pellets boiler engineer said, external circulating fluidized bed boiler lighting up is much easier than internal circulating fluidized bed boiler. This is because external cfb boiler adopts automatic ignition method, burning oil to start the whole boiler system at first. However, internal cfb boiler still uses manual ignition method, burning biomass pellet like wood to run the whole boiler equipment. As to boiler system cost, external cfb boiler is more expensive than internal cfb boiler.
Natural gas fired wood chip or wood pellets boiler is an inevitable trend of biomass transformation of straw pellet machine wood biomass combustion boilers has become an inevitable trend, as people's environmental awareness is gradually improving, countries and relevant departments of environmental protection and energy conservation incentives gradually introduced, burning reconstruction of coal boiler to a biomass fired boiler has become an inevitable trend. It is reported that wood biomass straw pellet production line capable of dispersing straw, wood and other raw materials processed into biomass burning particles, biomass fuel boilers provide a rich fuel, thus contributing to the transformation of enterprises biomass combustion boilers. Due to the strong state support, biomass burning particles as an alternative to coal, it has become China's fourth largest energy. British co-promote the use of wood biomass straw particle machine production lines, the production of biomass burning particles is greatly improved, greatly facilitate the process of enterprise biomass burning boiler in China. The increase in coal-fired boiler flue gas heat recovery steam recovery and necessary, and grate and transform a simple drum cited the wind, it can become a biomass wood pellet machine straw biomass pellet fuel biomass combustion boilers. While coal-fired boiler will increase business costs, but in the long run, the interests of biomass fuel boiler to the enterprise is immeasurable. With the contraction of the national policy on coal mining, the market price of coal is gradually rising. Biomass, straw wood pellet machine sufficient feedstock biomass particles, low processing costs, the use of biomass boilers, direct year savings of 5-10% in fuel costs. It is understood that use coal-fired boiler, the desulfurization necessary intervals, the biomass particles fuel sulfur content is extremely low. This complete abolition boiler desulfurization costs, reduce operating costs. Biomass fuel fired boilers can be exempt costs 80 yuan / ton; subsidies can help apply alternative fuel fired $ 200 / ton (NDRC); Also, according to the case of application of various energy saving MEP technological sector, the Ministry and other subsidies; where if a higher corporate income tax, then the application of biomass wood pellet machine straw biomass fuel particles can win policy tax shelters.
