The end of this type of boiler coil pipe adopts shrinkage coil, which effectively
protects the furnace wall at the end of the boiler and is equipped with
imported burners provide a wide operating range
central furnace tube to ensure safety and long life of the steam boiler shell
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 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.
Food factory operating costs Steam Boiler: food plant steam operating cost boiler analysis, including the sum of the electricity, natural gas costs, demineralized water (dose), labor costs and other costs required for the principle of conservation of the energy, the thermal efficiency of the boiler calculation is running at full capacity 97.94% . (1) The natural gas fuel heating value: Qdw = 8500 kcal / Nm3 = consumption of natural gas production of 2 tons of steam heat (heat value gas boiler thermal efficiency x) = 2,60,104kCal / h (8500kCal / Nm, 97.94%), 144.1 nm / h, and then consider the practical use of heat loss of about 3.8%, such as heat and water. A = 144.1 / (1-3.8%) = Cost 149.75,150Nm3 / h of gas per hour is run B = 150nm / h, 4.387 yuan / Nm (Yantai Industrial gas prices) 658 yuan / hr.
