new product lignite coal dhl boiler

ZG as a 70 years biomass coal fired CFB new product lignite coal dhl boiler manufacturer has a high technology on circulating fluidized bed. During the combustion phase, upwards jets of air will cause the solid fuels to be suspended. This is to ensure the gas and solids will mix together turbulently for better heat transfer and chemical reactions. The fuel will be burnt at a temperature if 1400oF to 1700oF to prevent nitrogen oxide from forming.While burning, flue gas such as sulfur dioxide will be released. At the same time, sulfur-absorbing chemical such as limestone or dolomite will be used to mix with the fuel particles in the fluidization phase, which will absorb almost 95% of the sulfur pollutants.

Steam new product lignite coal dhl 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.

The new product lignite coal dhl boiler induced draft fan is the equipment that removes the flue gas from the boiler, this kind of machinery is actually the same in the working principle, but the impeller of the ventilator is installed in reverse, then the air will be transported according to the opposite direction. Gas such as carbon monoxide will be produced by incomplete combustion of coal in the process of boiler operation. If these gases are not eliminated in time, the efficiency of boiler will be affected.

PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of ​​coal to gas projects in recent years, the country's use of gas-fired new product lignite coal dhl boiler more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.
