china vertical coal boiler

Steam china vertical coal boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.

(3) air preheater. Located in the china vertical coal boiler backpass, whose role is to use waste heat of flue gas to heat the fuel required for the combustion air, exhaust gas temperature can be further reduced not only, but also for strengthening the furnace combustion, improve the economy of combustion, pulverized coal drying and conveying is advantageous of. Boiler efficiency can be increased by 2%. And rotary two kinds of charge.

Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast china vertical coal boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .

Advantages of heating Boiler and Gas-fired heating BoilerOil-fired and gas-fired heating china vertical coal 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.
