Coal-fired steam boilers are fuel-burning coal, coal heat is converted to produce steam but not all the heat is effectively converted, there is a part of no work consumption, so that there is a problem of efficiency, generally larger boilers are more efficient, between 60-80%.
Control System of Coal-fired Steam Boilers
The coal fired steam boiler is a forced circulation high-pressure single-tube DC boiler. Its operation process includes three processes: the combustion process of the fuel, the heat transfer process of flue gas to water and the vaporization process after water absorbs heat. In order to better control these different processes, the control system should make the heat of pulverized coal combustion adapt to the requirements of steam load changes and dryness.
In other words, the purpose of the operation of the control system in a coal-fired steam boiler and the organic waste gas treatment is to keep the steam dryness and steam pressure in a certain range and improve the thermal efficiency of the steam boiler. Meanwhile, it is also necessary to adjust the amount of air blast, induced air, coal supply and water supply to maintain an appropriate proportional relationship between them. In addition, the control system should realize the automatic control of the boiler’s automatic ignition control and soot blowing process.
Energy-saving coal-fired steam boiler/coal-burning steam boiler adopts quick-assembly factory, easy and fast installation; the boiler has compact and reasonable structure, convenient for lifting and transportation. Widely used in hospitals, schools, textile factories, garment factories, garment supermarkets, garment factories, dry cleaners, restaurants, hotels, bakeries, hotels, canteens, restaurants, food factories, beverage factories, soybean factories, meat products factories, canneries, distilleries, pharmaceutical factories, packaging plants, building materials factories, paint factories, beauty salons, bathing centers, saunas, steam rooms and other places.
The coal-fired steam boiler is mainly composed of coal powder preparation system, burner, heating surface, air preheater and other major parts. Coal-fired steam boiler randomly equipped with high-quality instrumentation valves and other safety accessories, complete sets of equipment safe and durable, the user satisfied. Users can optional boiler water softening device – water treatment, the addition of water treatment, furnace gall bladder less scaling, boiler safety and energy saving.
