singapore oil fired steam boiler Agent 6 ton

Why boiler furnace exhaust gas temperature increases heat losses the heat loss is largest in a boiler, furnace 6% is generally fed to the heat, the exhaust gas temperature increasing every 12 ~ 15 ℃, heat losses to an increase of 0.5%. Therefore, the exhaust gas temperature is one of the most important indicators boiler operation. Here are a few reasons may cause the furnace exhaust gas temperature rise: (1) heating surface slagging, fouling. Whether waterwall slagging furnace fouling, or superheater, convection bank, and economizer preheater fouling are due to increased resistance measured smoke, heat deterioration of the cooling effect deteriorates the flue gas, resulting in increased exhaust gas temperature. (2) the excess air ratio is too large. Under normal circumstances, the furnace outlet increases as the excess air ratio of the exhaust gas temperature rises. After the excess air ratio increases, while the amount of smoke increases, the speed increase of smoke, heat strengthening of exiled, but less than the degree of increase in heat transfer gas volume increases more. It will be appreciated as the tobacco rate increased, the time to heat to the flue gas working fluid left the heating surface. (3) leakage factor is too large. Tail shaft furnace and boiler flue negative pressure leakage is inevitable, and provides a heating surface allowed leakage coefficient. When the coefficient of air leakage increases, the influence of the exhaust gas temperature and overfire air coefficient increases similarly. And the closer the leakage furnace, exhaust gas temperature raising effect on the greater. (4) water temperature. When the turbine load is low or high pressure splitting when the heater temperature of the boiler feedwater will decrease. Generally, when the water temperature rises, if the amount of fuel is maintained constant, the temperature difference decreases economizer, economizer heat absorption decreases the exhaust gas temperature rises. (5) the fuel moisture. The fuel in the flue gas to increase the amount of water increases, and therefore the exhaust gas temperature rises. (6) boiler load. Although the boiler load increases, the amount of smoke, the amount of steam to the water, the air amount increases in proportion, but since the furnace exit gas temperature is increased, so that the exhaust gas temperature rises. After the load is increased to increase the furnace outlet temperature, followed by convection heating surface temperature difference increases, an increase in heat absorption, the more so the convection heating surface, the smaller the impact load change of a boiler exhaust gas temperature. (7) The fuel species. When burning low calorific value gas, since the furnace temperature is lowered to reduce the radiation heat transfer in the furnace, the low calorific value gas in a non-combustible components, mainly N2, CO2, H2O more, the amount of flue gas increases, the exhaust gas temperature rise high. Pulverized after burning oil, although oil-fired furnace outlet when the excess air ratio than the coal is low, but the little ash fuel oil, and no larger soot particles, larger ash particles in the flue gas absent the cleaning action of surface heating, convection heating surface more polluting. So bad combustion, often black smoke boiler flue gas temperature. When the tail has means ash ball, since the tail cleaner, the exhaust gas temperature is slightly lower than the burning coal. (8) milling system operation. Bunker has a reservoir of closed milling system is concerned, when the pulverizing system is running, because a portion of the water in the fuel into the furnace, the furnace temperature is reduced and the amount of smoke increases, the leakage into the pulverizing system is running as the primary cold air air into the furnace, to reduce the amount of air flowing through the air preheater to the exhaust gas temperature rises. Conversely, when the exhaust gas temperature is reduced pulverizing system outage.

WNS2-1.25-Y / Q boiler What does this mean? Boiler models are more familiar with the customer, the purchase of Zheng pot gas boilers, will directly inform the model, but many customers only know about the parameters, do not know what type of boiler Yes. The following boiler factory in Zhengzhou on demand for larger WNS2-1.25-Y / Q boiler, for example, talk about the letters and numbers represent what it means. WNS2-1.25-Y / Q boiler. 1, WNS meanings, W: horizontal, N: the internal combustion type, S: water tube boiler WNS is represented as the horizontal internal combustion boiler water tube boiler, WNS can see that the boiler is determined Cheng pressure industrial boilers, industrial boilers is with a certain pressure, but that pressure boiler CWNS, with no pressure. Zheng pot boilers are produced under pressure industrial boilers, hope buyers understand that. 2, numeral 2 represents the meaning type of desired amount of steam of 2 tons of steam / h, which is a 2 tons of steam produced hour. The boiler singapore fired steam boiler agent 6 ton, can be used for the production of steam, high temperature sterilization lamp, of course, some need both for hot water or steam also requires heating customer will purchase steam boiler. 1.25 is the nominal steam pressure, which is the boiler pressure is 1.25MPa. Furthermore, it was expressed in kilograms vapor pressure expressed in units of kg / cm2.1N / m2 = 1Pa1kg = 9.8N1m2 = 10000cm2, so 1kg / cm2 = 98KPa = 0.098MPa, approximating that 1MPa = 10kg / cm2. WNS2-1.25-Y / Q boiler. 3, Y / Q meanings, Y represents a fuel oil, i.e. fuel of the boiler is a boiler; Q denotes a fuel gas, which is expressed as the boiler gas boiler; Y / Q indicates that the boiler can be either fuel gas. Through the above explanation, we can know WNS2-1.25-Y / Q boiler is a pressure of 2 tons WNS fuel gas steam boiler of 1.25MPa. If you want to know more boiler models, you can call the Henan fast Boiler Sales hotline: 0371-60922096, can also directly contact customer service online, we will provide you with professional boiler solutions.

35 tph SHL series field assembled chain grate singapore fired steam boiler agent 6 ton for oil refining industryIn the refining industry, steam is the main factor affecting the energy consumption of enterprises, which directly determines the quality of oil products and the economic benefits of the enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. It was founded in 1939. After several decades of development, it now has a crude processing capacity of 6.5 million tons per year. The main products include gasoline, jet fuel, diesel, petroleum coke, etc. In recent years, Jinxi Petrochemical has accelerated its pace of development and is in urgent need of introducing a high-efficient and energy-saving boiler system. Regarding the actual production needs of Jinxi Petrochemical, ZOZEN recommended the safe and efficient SHL series field assembled water tube steam boiler and tailored the boiler system technical solution. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler. The steam boiler provides sufficient and high quality steam heat source for the production line of Jinxi Petrochemical.

In recent years, the state environmental protection is all the more attention we as a company with the times, in order to respond positively to the implementation of the national environmental protection requirements from coal to gas project. But the choice of boiler suppliers in this area quite a headache, after repeated comparison and investigation, we chose to partner with fast boiler. Fang did not disappoint quickly proved that the recommended boiler operation after use to fully meet our needs, both energy saving and environmental protection, high thermal efficiency, to a certain extent, cost savings for our fuel. --customer feedback
