coal gas hot air boiler

How to maintain the coal hot air boiler shutdown? After boiler shutdown cooling, heating surface must be thoroughly cleaned of fouling and ash grate the upper, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. How to care? If the boiler shutdown a long time, the boiler shutdown after complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As internal corrosion Maintenance shutdown of the boiler body, under normal circumstances, can be used wet shutdown maintenance is not more than one month, one month electrically operated steam boiler should be taken to dry more maintenance. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover.

Saudi Arabia is known as the kingdom of oil, and is one of the largest oil reserves, output and sales in the world.proven oil reserves is 500 tons and natural gas reserves is 34885 million cubic meters in 1984.So the fuel of industrial coal hot air boiler mostly be diesel oil in Saudi Arabia.

"Can shipped on time, not only the ability to schedule Tianjin coal-fired coal hot air boiler project and the Tianjin Municipal People spend time heating, but also on our fast boiler brand image, so we have to work overtime quality and quantity the coal-fired boiler complete product supply mission. "fast square to official said. Facing short construction period, heavy task difficult, we rationalize production processes, all front-line staff hard working, eventually will be shipped on time to the boiler Tianjin, and running. After the boiler in place, Tianjin coal-fired boiler project also completed the basic preparation, coal-fired boilers, Tianjin is also a blue sky will gradually improve and advance. Tianjin transformation of coal-fired boilers, fast Boiler contributed.

Environmental protection coal hot air boiler use different fuel characteristics of each boiler using environmentally friendly fuel What? Common energy-saving environmental protection boiler fuel natural gas, diesel, electricity and methanol. 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 thermal efficiency of gas-fired Stone 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 a need to place special attention. Environmental protection boiler thermal efficiency of methanol selection of energy-efficient boilers, facilities storage tank is required, but also the Government's strong support for environmental protection boiler.
