differentiate low medium and high pressure boilers
What is the reason of the rapid development of the gas differentiate low medium and high pressure boilers? As technology advances the efficiency of the boiler equipment has also been upgrading a lot of times, a new generation of gas-fired boilers are research and development costs, mainly energy this equipment from the gas boiler, use only very convenient, but to boil water It has been effectively improved. Today's gas-fired boiler has been applied to many industries, for people to bring efficiency also brings development. In the domestic market in the boilers, gas boilers can be said to have almost replaced other types of boiler equipment, but the main reason is because of their high efficiency and safety of the gas boiler, safety and efficiency are issues the industry will consider when choosing a boiler , fitness of these two gas-fired boilers will be reflected most vividly in the conventional boiler equipment, there have been many problems, to staff their own security and development of the industry have caused serious injury. The advantages of gas-fired boiler itself have very much, but also for the industry to save energy is also very much the industry input costs to a minimum, in the past, the use of staff in the use of traditional boiler equipment, several staff members need to invest in order to control it is for the industry to increase a lot of cost, which is to contain one of the main development of the industry, although the industry also found this, but the reasons behind the technology, which is also very helpless industry.
What should pay attention to the large steam differentiate low medium and high pressure boilers on the installation? How to choose a steam boiler? Boiler energy transfer apparatus itself, the conversion ratio of the energy input and energy boiler and fuel, the conversion of heat energy to chemical energy in the high temperature steam boiler in a large current, often seen, due to the rapid conversion of energy such high temperatures and organic heat carrier, with subsequent changes in the water container. Steam boilers, as well as places than fuel efficiency, and enhance the market are very rapidly, after generating hot water or steam boiler, should provide heat from industrial production methods and way of life of the people, to avoid because the problem of power steam source device changes, or changes in mechanical energy, which led to the use of electricity or machinery, produce too much complex phenomenon. Hot water steam boilers known as water heaters, the use of life among industry and the use of follow-up among a small number of applications as well as long-term use have reached a high degree of industrial principle point of view, the release of heating equipment heat conduction and subsequent radiation, with subsequent absorption cold wall, boiling water, and the gasification process, have a very good effect on the classification point of view, according to the classification of the fuel steam boilers, steam boilers can be classified into electrical, fuel vapor gas boilers and steam boilers. According to construction, can be divided into a vertical steam boiler, steam boiler is horizontal, and other small steam boiler into, now the choice of steam boilers should be aligned in accordance with the structure and the overall structure of the bedroom to avoid, because the choice steam boilers, as well as related series of overly complex and result in an overall cost-effective, high-end boiler and the problems of purchase.
5. Boiler water wall, convection tube bundle, economizer tube or pipe blasting venting water vapor.
Accurate understanding of boiler heating surface
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 differentiate low medium and high pressure boilers, 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.
