Gas and coal-fired steam coal fired horizontal boiler steam boiler at any time there is any good compared to the country more and more attention to environmental protection, coal-fired steam boiler has been a great blow, and relatively gas steam boiler by many users of all ages, in recent years the country also vigorously promote the use of gas-fired boiler, then what are the benefits of gas compared with coal-fired steam boiler steam boiler it? And today we work together to explore. Gas-fired steam boilers and coal-fired steam boilers on the market each accounted for half of the country, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of coal-fired boilers, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, than the price of coal-fired boiler gas boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more coal-fired steam boilers, so the boiler room construction funds have more. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The coal-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than burning coal per hour to be much more. 4. environmental costs: in the need to protect the environment, review the current coal-fired boiler more strict. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used.
The final step is to select which type of steam coal fired horizontal boilers currently on the market have the type of fuel boilers, electric boilers. Due to the current state for the "coal to electricity," the advocate, more companies may choose an electric boiler, but there are energy consumption, safety issues such as the traditional electric boiler, by contrast, the crown than conventional electric steam boilers boiler energy saving more than 30% compared to conventional steam boilers have increased security.
Environmental situation is not optimistic that China has issued a number of environmental policy, the full range of safeguards ecological environment. Provinces are also actively to improve environmental protection, recently, Ningxia Hui Autonomous Region winter heating coal fired horizontal boiler proposed implementation. details as follows.
"Clean heating embodiment of Ningxia Hui Autonomous Region (2018 Year - 2021)," recently released, "plan" put forward, Ningxia heating the status quo, to develop clean heating, the use of clean energy alternative to coal and dispersed living coal, reducing coal consumption and soot emissions, improve environmental quality in urban and rural atmosphere.
By the end of 2017, Ningxia urban and rural housing construction for heating a total area of 380 million square meters, of which the city building heating area of about 240 million square meters, rural buildings for heating an area of about 140 million square meters. Clean heating total area of about 180 million square meters, accounting for about 47% of the region's total heating area. Among them, prefecture-level city clean heating an area of about 120 million square meters, clean heating rate of about 75%; counties (cities, districts) Clean heating an area of about 50 million square meters, clean heating rate of about 62%; rural clean heating area of about 14.72 million square, clean heating rate of about 10%.
After the "plan" put forward, Ningxia, according to the "central heating mainly to the substitution of gas for coal as the first, supplemented by electricity instead of coal," the idea, according to local conditions, scientific planning, coordination implementation. City, county (district) the main city clean coal-fired co-generation, large-scale energy saving boiler central heating heat source as the basis for strengthening efforts to shut down within a small range of central heating boilers of coal. Promote cogeneration units and ultra-low emissions transformation of large boilers, improving the environmental standards.
In urban and rural interface and rural areas, in accordance with the principles of the easier issues first, and start cleaning centralized heating schools, kindergartens, hospitals and other public buildings start to play an exemplary role. The conditions of the area to promote gas boiler; encourage nearby collected plant biomass feedstock, biomass briquette forming process instead of bulk coal; encourage livestock waste, straw and other raw material for the biogas fermentation and purified, for clean heating; actively promote the development of geothermal resources as a centralized or decentralized heating heat source; support for residents to install solar hot water, electric heating equipment, such as housing, agriculture greenhouses, farms; do not have clean heating conditions actively implement clean coal alternative bulk coal.
"Plan" clearly, Ningxia will accelerate cogeneration, waste heat utilization, the cell set into a piece of construction heating boilers, focusing on the completion of the Western Xia thermoelectric (two) central heating, in Nanjing Tianyuan thermoelectric, Helan back pressure Heating Unit central heating and other projects, the completion of thermoelectric Zhongwei, Wuzhong thermoelectric, thermoelectric Dawukou LIUPANSHAN thermoelectric renovation project, to further expand the central heating area. City, county (district) heating should vigorously promote the "coal to gas," "coal to electricity", according to local conditions the development of renewable energy for heating, a pair of old, energy-saving secondary pipe network, heating network system to enhance efficiency.
Ningxia will be fully phased out small coal-fired boilers, coal-fired boiler to deepen the comprehensive compliance management, municipalities, county (district) urban area out of 20 tons of steam / hour coal-fired boilers. Yinchuan City urban area to total phase-out project cogeneration district heating pipe network covering all coal-fired heating boilers in the region. It does not have the "coal to gas," "coal to electricity" conditions in rural areas, to achieve clean coal production and warehouse distribution center full coverage, full implementation of clean coal alternative bulk coal.
Ningxia Hui Autonomous Region in the 2018-2021 four-year, with the full complement of winter heating boiler, will replace all cleaner energy boiler coal-fired boiler, to protect people's health.
Fossil fuel prices rise substantially and bring serious environmental pollution, the government had to take the coal ban policy, in this case, the biomass coal fired horizontal boiler steam supply favored by the market, this article mainly introduces how to operate biomass steam boiler for enterprises which purchased a biomass steam boiler.
