The bed temperature control parameters directly affect the important safety CFB single drum series boiler can run continuously, but also directly affects the generation of boiler operation of the desulfurization efficiency and NOx. Usually ultra high temperature CFB boiler bed temperature control between 790V~900 ° C, the temperature of the furnace is the optimum temperature to achieve desulfurization. Not only will decrease the bed temperature is too low boiler efficiency, it will result in the boiler unstable and prone to fire. Bed temperature is too high will cause the furnace desulfurization efficiency decreases and the amount of NOx will be greatly increased, but also likely to cause material coking furnace bed, and if the situation coking furnace bed material must be shutdown occurs. Therefore bed temperature control is critical for ultra-high temperature boiler CFB.
So for now people see in many cases gas single drum series boiler better to take into account the time, because there is a lot of equipment inside the controlled dangerous side effect, which is to ensure that equipment can run better, and better use of a good way, consumers are better able to understand the different aspects from such a situation, after all, such a product to a good attention to when, or well implemented.
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 single drum series 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.
Heating many users will choose two or more sets of hot water single drum series boiler, together with the use of the benefits of doing so are threefold. 1, when the heating is in the peak period of three boilers can be operated at high load conditions, to meet the heating needs. 2, when the heating temperature is less demanding, which can initiate one or two boilers, while satisfying the need of heating, to reduce fuel consumption. 3, when a boiler regular maintenance, the other two can high-load operation, to meet the heating needs, not to delay the construction period. Second, the gas consumption of gas pressure hot water boiler runtime
