Why are gas-fired ce replace coal fired boiler loved it public due to the nature of our resource structure, the proportion of coal resource structure had relatively large, so the gas boiler is also a time position in the market significantly. However, with the recent changes in the structure of resources, and the environment pollution situation, relying on natural gas-fired boiler advantage is gradually replacing gas-fired boiler, a new main market. gas boiler market position became clear, that has its own distinct advantages, the following comparative analysis of the advantages of gas-fired boiler. gas boiler natural gas as fuel, the fuel burning quickly, the power generated by large, so efficiency is high, compared with 50% efficiency gas boilers% higher. While natural gas prices higher than the price of coal, but in addition to fuel other than the cost, as long as the investment conduit can be. gas boiler is not the same, in addition to fuel costs, as well as transportation costs, labor costs, storage costs, the overall price is not cheap, so from a cost point of view, natural gas overall advantage. Because natural gas itself sufficient combustion and clean burning, non-polluting emissions, it is by far one of the most environmentally friendly energy up. coal combustion emissions Sulfur points, more ash, environmental pollution more serious, which is incomparable with gas-fired boilers. Gas boilers can bring greater environmental benefits to the enterprise.
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.
What are the reasons biomass ce replace coal fired boilers incomplete combustion? Biomass boilers used in modern industry, not only solve the problem of environmental pollution produced by conventional boilers, but also reduces the use of coal and other resources. However, in the products of combustion of biomass boiler, we sometimes found to contain a large amount of combustible material, and black ash, and combustion gas contains a lot of carbon monoxide combustible components. Such a phenomenon is a typical problem of incomplete combustion.
WNS type ce replace coal fired boiler and gas boiler SZS What's the difference? After the state has increased in recent years, efforts to manage the environment, improve air quality, all walks of life are generally boiler retrofit or replacement gas boiler became a coal-fired boiler, the implementation of coal to gas boilers in large-scale, often encounter some customers when purchasing gas boiler, except consulting WNS type boiler and gas SZS type gas boiler, which both thermal efficiency higher? Now, I give you a brief overview about the difference between the two.
