oil fired condensing boiler high efficiency
February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.
First, strictly control the total coal consumption
The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.
Second, to strengthen control bulk coal
Full implementation of the "Harbin coal pollution prevention and control regulations" to strengthen quality inspection of coal, coal quality testing organizations standardized sampling, testing system, improve the sampling frequency. Promote clean and efficient coal-fired boiler, wherein an alternative embodiment the biomass must be dedicated biomass boiler, burning raw material briquettes, installation efficient dust removal equipment.
Third, steadily promote clean heating
To promote priority to the development of clean coal utilization and clean energy use, urban urban central heating. Being difficult to cover central heating, gas heating and accelerate the implementation of electrical heating and other heating decentralized cleaning implement "coal to clean energy" units should be synchronized removal of coal-fired boiler, gas boiler for an alternative to the use of low NOx combustion technologies , gas boiler efficiency can not be less than two levels. 2019, clean heating rate of more than 60%; in 2020, clean heating rate should reach 70%.
Fourth, to carry out comprehensive improvement of coal-fired boilers
To develop a comprehensive remediation plan coal-fired boilers, the implementation of cleaner alternative to coal-fired heating boilers. 2019, the urban built-up area, county (city) county towns built-up areas out of 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal fired facilities; basic urban built-up area out of 35 tons of steam per hour coal-fired boilers; basically eliminated the urban fringe per hour 10 tons of steam coal-fired boilers; county (city) basically out of the city and county (city) financial support units (including township, village ) per hour, 10 tons of steam coal-fired boilers. By 2020, basically out of 10 tons of steam per hour urban coal-fired boilers; out of the urban built-up area per hour can not discharge standards of 35 tons of steam (or 29MW) coal-fired heating boilers. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired boilers.
Fifth, accelerate clean energy development
Orderly development of wind power, wind power construction layout optimization, to carry out decentralized wind power development and construction in the area have developed criteria. Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.
Center back fired condensing boiler high efficiency combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas boiler SZS improve thermal efficiency because the oil, gas type SZS easy to burn the fuel gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature.
As this consumer added, he wants to fire gas fuel and automatic operating system. Thus, our sales manager recommend him WNS type, single drum, horizontal structure, firing oil and gas. WNS 2000 kg steam fired condensing boiler high efficiency working together with autoclave can ensure the brick manufacturing process smoothly and successfully. Its horizontal structure and integrated design is very good-looking, and convenient to transport.
Three main reasons for low nitrogen fired condensing boiler high efficiency been promoted in our country into the 21st century, mankind's most concerned about what issues it? Is the energy and environmental issues, and this is our country insist on one of the key strategic issues of sustainable development. Because of today's economy, the boiler has become an integral part of people's lives thermal power plant, but a large number of pollutants boiler emissions also increased air pollution. Low nitrogen boiler in this harsh environment, the advantage will be reflected. 1, to promote the cause of low nitrogen boiler (strong environmental protection) in accordance with environmental requirements, the country's industrial vigorously implement the project boiler clean energy transformation of small coal-fired boilers to be changed to "oil, gas or electric boilers" and other new energy device. Especially in recent years in Beijing, Tianjin and the Northwest Regional haze serious, and therefore improve the national environmental emissions requirements for industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented the most stringent in the history of NOx emission standards, accelerated energy consumption low on nitrogen boiler marketing process. 2, premix combustion technology (combustion efficiency) boiler low nitrogen combustion technology to more advanced, its relatively low contaminant-free index, and the proportion of the fuel is more suitable, low nitrogen combustion more fully boiler can be significantly reduced overall energy consumption, and its flame propagation speed is relatively fast, relatively high intensity combustion can be continuously supplied heat orderly, the relevant parties, the kind of low nitrogen boiler almost no worry about another problem of insufficient chemical combustion . 3, low nitrogen boiler energy conversion (which is the highest thermal efficiency) boiler is an energy conversion equipment, professional production of low-nitrogen boiler as available and high-grade thermal energy necessary for life, for gas boilers, machinery (solid) Incomplete Combustion Heat loss and ash physical heat loss is negligible. Want to improve the efficiency of the boiler, the boiler only reduce heat loss and heat dissipation reduce exhaust gas temperature. For public projects, the general municipal heat and user-created central heating boiler room heating these two forms. The use of low nitrogen boiler heating system, low nitrogen boiler system has a very high load regulation may well match the user load changes, operating significant energy saving effect for the user to save operating costs, should allow a low nitrogen boiler widely used in public projects .
