5000kg hr waste wood steam boiler
Biomass Based Power Generation
The potential of bagasse/co-generation in Zimbabwe is estimated to be 633 GWh, particularly from sugarcane. There is also the potential for power generation from wood waste generated from the timber industry with over 70,000 tons of biomass waste each year. In the long-term, this figure is projected to double by 2015. At most large timber mills, only a small fraction (~10%) of wood waste that is generated, is currently consumed in process steam boilers for lumber drying kilns, while the vast majority is burned in the open air or dumped. It’s estimated that at least 4 MW of power could potentially be generated from waste that is produced from large mills.
The boiler is efficient, reliable and cost effective.
The functions of 6 tph wood biomass steam boiler in wood processing
In this method of combustion, coal fuel is burned in a bed of hot inert, or incombustible, particles suspended by an upward flow of combustion air that is injected from the bottom of the combustor to keep the bed in a floating or “fluidized” state. The scrubbing action of the bed material on the coal fuels enhances the combustion process by stripping away the CO2 and solids residue (char) that normally forms around the coal fuels particles. This process allows oxygen to reach the combustible material more readily and increases the rate and efficiency of the combustion process. One advantage of mixing in the fluidized bed is that it allows a more compact design than in conventional water tube boiler designs. Natural gas or oil fuel can also be used as a start-up fuel to preheat the coal fired steam fluidized bed or as an auxiliary fuel when additional heat is required. Beside, the effective mixing of the bed makes fluidized bed boilers well-suited to burn solid refuse, wood waste, waste coals, and other non standard fuels. The fluidized bed combustion process provides a means for efficiently mixing fuel with air for combustion. When coal fuel is introduced to the bed, it is quickly heated above its ignition temperature, ignites, and becomes part of the burning mass. The flow of air and fuel to the dense bed is controlled so that the desired amount of heat is released to the furnace section on a continuous basis.
Recently, the Hebei Langfang municipal government office "ten policy measures to support Hebei Province to promote the transformation of key industries and Ultra Low Emission Boiler (depth control)," according formulated and issued a "Langfang City to promote the transformation of key industries and Ultra Low Emission Boiler (depth governance) policy measures to support ten "(the" measures "), and comprehensively promote the iron and steel, cement, glass and other key industries and the transformation of ultra-low emissions of pollutants boiler, boiler-fired power plant pollutants depth governance.
"Measures" mentioned, strictly implement the "smooth approval of the green channel" to further deepen innovation and entrepreneurship, service development, people's livelihood-oriented "double hit double service" activities, enhance the quality and speed double simplify the above key industries and boilers the transformation of ultra-low approval procedures ultra-low emissions of air pollutants and other projects, the implementation of government-supported environmental protection equipment investment tax credit policy. The strict implementation of the relevant departments of the Ministry of Finance and other five, 10% of investment in environmental protection equipment mortgaged year corporate income tax liability; subsidies to varying degrees according to differences in the concentration of atmospheric pollutant emissions enterprise latest boiler equipment. For complete depth reduction of atmospheric pollutants and acceptance of coal-fired power and stable operation,
1, lower than the pollutant emission standards of the national and local pollutant emissions taxable value of atmospheric concentration of 30%, 75% reduced rate of levy environmental taxes;
2, lower than the pollutant emission standards in the country and 50 percent of local emissions of the taxable value of atmospheric concentration of pollutants, reduced rate of 50% levy environmental taxes.
"Measures" requirements, to strictly implement the "smooth approval of the green channel" system, continue to deepen the "double hit double service" activities, further upgrading speed, simplify examination and approval procedures, steel, cement, glass and other industries, ultra-low emissions of air pollutants boiler depth reform and governance project pollutant coal power plant; to implement environmental protection equipment investment tax credit policy, to carry out the depth of air pollutants emissions coal power plant, ultra-low emissions transformation of iron and steel, cement, glass and other enterprises and boiler emissions reconstruction project, the Ministry of Finance and other five departments to strictly implement the relevant documentation requirements, the implementation of a 10% investment in environmental protection special equipment to deduct year corporate income tax liability; to implement environmental protection tax relief, to complete the transformation of ultra-low emissions and acceptance stable iron and steel, cement, glass and other enterprises and boiler and emission reduction projects running, complete air pollutant emissions by coal-fired power plants deep acceptance stable operation of the emission of pollutants below the taxable value of atmospheric concentration of pollutants prescribed by the state and local 30% of the emission standard, reduced environmental taxes levied 75%; emission of air pollutants concentration value lower taxable National and local regulations on pollutant discharge standards of 50%, 50% reduced rate of levy environmental taxes; to guide benchmarking upgrading strict iron and steel, cement, glass and other industries, the transformation of air pollutants and ultra-low emissions coal-fired boiler power plant emissions of pollutants EIA depth governance project approval, strict implementation of Hebei Province on ultra-low emissions of iron and steel, cement, glass and other industries and atmospheric pollutants boilers, coal-fired power plant emissions depth local standards. To carry out the EIA approval, pollution permits, environmental supervision and law enforcement services double forward, promote cleaner production, guide enterprises to upgrade pollution control facilities, strengthen fine management, promote the production of green, clean; to give priority to conduct emissions trading . Start as soon as the secondary market trading emission rights, to carry out the depth of emissions of air pollutants and ultra-low emissions of coal-fired power plant transformation iron and steel, cement, glass and other enterprises, boilers and emission reduction projects, the formation of sulfur dioxide, nitrogen oxides emissions amount, priority emissions trading, emission reduction achieved early, early benefit, large reduction, big benefit; promote emission right mortgage loan; to recommend inclusion of advanced technology directory; the implementation of differential pricing policy; to implement load shifting production of differentiated management , in accordance with provincial requirements for stability and achieve ultra-low emissions standards acceptance iron and steel, cement, glass and other enterprises and boilers, as well as in-depth treatment and complete acceptance by coal-fired plants, the implementation of green scheduling, in accordance with the relevant policy requirements appropriate to reduce or avoid peak load shifting production to heating season; to support the selection of units involved in green, continued to improve air quality, and resolutely fight win battle of blue sky.
