1, compared to the traditional coal-fired anthracite coal fired boiler, gas boiler higher cost low nitrogen
Conventional coal-fired boilers is generally filled manually directly into the coal combustion furnace, this method results in very large combustion sulfide, soot and other harmful substances discharged into the atmosphere pollution index high; but also need to manually plus fuel, time-consuming and labor-intensive, more harm than good.
Advantages of heating Boiler and Gas-fired heating BoilerOil-fired and gas-fired heating anthracite coal fired boilers all belong to chamber-fired boilers. The fuels used are injected into the furnace by burners and no cinder will be produced after combustion. This type of heating boiler does not require the complex and huge crushing of coal-fired boilers, facilities for conveying tender coal and equipment for burning and dedusting, so it is compact in structure, small in size, light in weight, small in land area, small in pollution and high in automation. Cities and boiler houses that require high environmental protection and prohibit the use of coal-fired boilers are used in large quantities in areas and units with high technical requirements for heating regulation. Medium and small boilers generally use light diesel oil, large-scale oil-fired boilers burn more heavy oil. Due to combustion The boiling point of oil is always lower than its ignition point, so the fuel is usually gaseous. After heating, the fuel is vaporized into oil vapor. After the mixture with air reaches a certain temperature, it starts to ignite and burn. In order to enhance the degree of vaporization of fuel, the fuel is often atomized into small droplets into a man-made furnace, heated by high-temperature flue gas in the furnace, and quickly vaporized and mixed with oxygen in the surrounding air, starting to ignite and burn. Some of the heat after burning is passed to the oil droplets, which vaporize and burn until they are exhausted.
Gas anthracite coal fired boiler gradually replace coal-fired boilers become the new main market: Due to the characteristics of the resource structure of our country, the proportion of coal resource structure had relatively large, coal-fired boiler was once standing in the market significantly. But with the recent changes in the structure of resources, as well as countries in recent years greatly improved Huanjingwuran situation, gas boilers With environmental protection, pollution-free natural advantage is gradually replacing coal-fired boilers, has become the new main market. Ding boiler is also actively respond to national call, to the gas boiler to transform, optimize, following the Central senior professionals tripod boilers for everyone to resolve the next several advantages and economic benefits of gas-fired boiler.
We learned from Zhenjiang Municipal Environmental Protection Bureau, to further promote the Battle of Blue Sky, enhance air quality, the city actively carry out biomass anthracite coal fired boiler investigation and remediation work has been completed seven bathrooms demolition of straw biomass boiler work in built-up urban area .
Biomass boiler pollution remediation has been a major focus of air pollution control, some of the city bathhouses, hotels, restaurants in the use of raw materials process boilers, illegally blended with coal, waste wood, waste and other substances, not advanced treatment of smoke, nitrogen oxides and other pollutants directly into the atmosphere, some impact on air quality.
According to relevant regulations, Zhenjiang city, the city built the region prohibited the use of straw biomass boilers, the current investigation and the bathroom were 10 straw biomass boiler, in which 7 have been removed, two shutdown ready transformation. At the same time, straw biomass boiler outside the urban area will be completed before the end of June classification renovation work, all dedicated boiler using biomass briquette students, prohibit blended with other fuels, coal, wood, etc., and must complete the construction of the bag efficient dust embodiments, emissions guarantee compliance.Free Chat
