coal and hot oil boiler

BOILERS deposited combustible material, such as carbon black, oils idle, coal, etc., it is mainly due to incomplete combustion of the tail into the coal and hot boiler. Especially when the ignition and shutdown, most likely to cause incomplete combustion, the rear of the boiler deposited a large amount of combustible material. These deposits reduce the heat transfer surface of the tail heating the exhaust gas temperature rises. When the exhaust gas temperature rises to a certain value, there is sufficient oxygen combustion condition occurs at the secondary combustion, secondary combustion is in the shutdown some minutes or hours after the occurrence, which is the ignition point of combustible material and heat conditions. Running faster flow of the flue boiler, heat of the combustible substances produced smoke away quickly, only a slow oxidative, ignition combustion can not be achieved. After the shutdown, the gas flue, the flow is stopped, the heat generated by the oxidation of combustible material not easily lost, the temperature will rise. If the door or flue damper closed tightly, leakage into the fresh air for combustion, causing secondary combustion after shutdown.

Tell you what fuels are environmentally friendly coal and hot boiler environmental protection boiler fuel for what? Many customers mentioned this problem, it seems everyone is still very concerned about this issue. These are summarized in environmental protection boiler, after reading it I believe you have a clear answer to this problem. First to note is environmentally friendly boiler is a more general concept. It is not classified according to the fuel used, but to a variety of standard boiler flue gas emissions to meet state regulations. So what are environmentally friendly boiler fuel to use it? Commonly used natural gas fuel, diesel fuel, electricity, methanol and the like. Natural gas is the most important environmental protection boiler, its fuel natural gas is a clean energy, combustion products discharged after treatment safety. Natural gas boiler maintenance costs of environmental protection is very low compared to the energy efficiency of is very high, such as our gas-fired thermal efficiency can reach 95%. This boiler is the government's most important eco-friendly boiler. Environmental protection boiler fuel diesel fuel use in general, because of the relatively low price of diesel, sulfur dioxide and other acidic substances produced by burning it after treatment can be safe discharge standards, supporting measures that it needs storage tanks, maintenance costs are lower thermal efficiency up to 90% or even higher. Electric heating boilers are environmentally friendly boiler, wire and cable facilities is required, it is zero pollution, low maintenance costs, but the state has requirements of energy conservation, power cuts in some places the situation may occur, especially in summer the peak period. This is also where you need particular attention. High energy-efficiency boiler hot methanol, facilities storage tank is required, but also the Government's strong support for environmental protection boiler. Over the years our country is more fog and haze, especially in northern areas and even worsening trend. This has aroused widespread concern. Haze days gives direct harm that affect people's mood, who see the blue sky not feel comfortable? I believe you have such an experience. Now the country strong regulation of air pollution, to govern from the source, many regions have issued a specific task, some regions have become a ban on coal zone, small gas boiler is accelerating the demolition work, the Ministry of Environmental Protection inspection teams to all designated areas can be examined, found to have concealed false hair had ordered its rectification. Government efforts to organize air pollution is evident. Now environmental protection boiler became the new alternatives, it is to advocate for and support the government. Through the above energy-saving boiler to summarize your introduction, I believe you are what fuel boiler and environmental protection have a deeper understanding.

Biomass fuel in CFB coal and hot boiler analysis

Biomass is a kind of fuel that is more and more often used in the energy industry. It supplements coal and allows it to meet the requirements of producing “green” energy and limit CO2 or sulphur emissions. Research refers to the ash originated from the combustion of the lignite with and without the wood biomass in the CFB boiler. This article shows the results of research into physical-chemical properties of fly ash obtained from the combustion of the lignite with and without the wood biomass (wood pellet). The possibilities of the use of this ash include in suspension technologies widely used in coal mines.

This year, Harbin, Heilongjiang Province, the financial sector to actively promote the elimination of coal-fired coal and hot boilers, and adjust the phase out coal-fired boilers financial subsidies, currently co-financing of 291 million yuan to support the city's coal-fired boilers out of work.

Combined with the characteristics of this year's work out coal-fired boilers Harbin, Harbin Finance Bureau jointly relevant departments to improve the policy adjustment, will expand the scope of the grant to build outside the area 10-20 tons of steam coal-fired boilers built-up areas and 10 tons of steam and less fuel coal boiler. Meanwhile, according to the actual situation of Harbin clean energy alternative work policies to increase financial assistance "from coal to biomass" approach; and to develop a more favorable subsidy policy of clean energy transformation of the urban fringe, the energy-saving house into the scope of the grant.

It is reported that, according to the above subsidy policy, the current urban levels, the financial capital of 291 million yuan has been implemented, which has been ahead of municipal finance district grant funds allocated 159 million yuan, 132 million yuan of the burden of the district also implemented through subsidies for local government bonds ways , effectively protecting the city out of coal-fired boilers work smoothly, since the Harbin into the winter heating period, ranked in the top 20 of 169 major cities in air quality rankings.
