Further promote air pollution control work, the Office of the ecological environment of Shanxi publicly stated: Shanxi Province will strictly control the total coal consumption; reduce the proportion of coal in primary energy consumption; Where ban on coal sales area of coal and coal products, both will be subject to heavy penalties.
Shanxi Province has also developed regulations, Municipal People's Government in accordance with the requirements to improve the quality of atmospheric environment, urban built-up area designated as the ban on coal zone, and gradually extended; counties (cities, districts) People's Government may delineate the scope of ban on coal zone according to the actual situation but life should be a primary consideration the needs of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.
At the same time, governments at all levels in Shanxi province will also strengthen civil bulk coal management, prohibit the sale, does not meet the civil standard of quality coal for coal; prohibition of lignite, coal washing, slime and other low-quality, low-grade coal as a civilian coal use. Various localities will accelerate the cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion of distributed coal-fired heating boilers; central heating pipe network coverage prior to the completion of use of scattered coal-fired heating boilers have been built and can not meet emissions standards coal-fired heating boilers, demolition will be completed within the deadline.
For violation of the provisions, sales do not meet the quality standards of civilian coal for coal, or the ban on coal sales coal region and its products, the people's government above the county level by the market supervision and management department confiscated of raw materials, products and illegal income, impose a fine of three times the value of the amount more than doubled.
Why should regularly which fuel is traveling gate in boiler decoking and put ashes? All contain a certain amount of the solid fuel ash, coal-fired boiler combustion process fly ash and cinder there will be generated, cinder ash hopper falls cold fly ash particles may fall into a large economizer while passing through the tail, discharge hopper in an air preheater, and then you need to put the ash slag periodically, in order to avoid plugging and blocking ash residue. In addition to focus and put the ash is not timely, it will cause Heating Surface temperature rise, so that the heating surface coke heavy, causing steam temperature rise, damage the water cycle, increased exhaust loss, when coke is serious, it will result in boiler output decline. When severe fouling, can also block the tail channel, even forced shutdown for maintenance.
Mining industry in Zambia is develop mature relatively.One mining factory in Zambia purchase a 25 ton circulating fluidized bed which fuel is traveling gate in boiler recently.The model number is SHX 25-1.25/300.
In addition to traditional industrial coal-fired which fuel is traveling gate in boiler steam boilers to natural gas, the natural gas steam boiler operation was also able to take energy-saving measures. Xiao Bian finishing the following natural gas steam boiler energy-saving measures:
1, the amount of industrial production according to demand reasonable selection of steam power rating and the number of boiler units of natural gas steam boiler, the higher the actual use of these two conditions matching the more obvious missing smoke less, energy.
2, the fuel and air full touch: make the right amount of air and an amount of the fuel composition of the best ratio to be burned, so that not only the progress of the fuel burning power, but also reduction of emissions of polluting gases, two complete energy policy.
3, the decline in gas steam boiler exhaust gas temperature: the temperature drop of useful heat recovery boiler using exhaust smoke is generally produced in the power boiler used is 85-88%, the exhaust gas temperature is 220-230 ℃. If the setting of energy-using the exhaust heat or the like, the exhaust gas temperature falls to 140-150 deg.] C, the boiler power may be increased to 90-93%.
4, the use of heat recovery boiler blowdown water: heat after heat exchange successive sewage water use, water temperature progress in addition to itch water saving gas steam boiler intention to arrive.

A fuel-heated boiler must provide air to oxidize its fuel. Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber.Get A Quote
These Boilers have intrinsic features for the operation of trouble-free and high-thermal efficiency. These are classified based on the technique of supply fuel to the boiler & with the grate type.
