reliable i300 professional steam boiler dubai
When the water temperature increase, due to the economizer heat transfer temperature difference is reduced, reducing heat absorption, enhance the tobacco temperature economizer, air preheater temperature and pressure increase, increase heat transfer, the hot air temperature increased slightly, smoke the temperature rises, so that boiler efficiency is lowered. However, after the water temperature increase, increase in the heat for evaporating the evaporation increases. In order to maintain unchanged the amount of evaporation, it is necessary to reduce the amount of fuel, which makes the exhaust gas temperature is lowered to improve the thermal efficiency of the boiler. Because of these two factors on the thermal efficiency of the boiler roughly, therefore, when the constant holding evaporation boiler, the thermal efficiency of the boiler feed water temperature increase substantially unchanged.
High capacity needs high technology. To ZG Boiler, boiler technology is all. Each year, our company send young engineers to abroad to learn foreign technology on boiler developments. We also exchange ideas with domestic excellent boiler manufacturer such as Haguo, Hangguo, etc. ZG Boiler, located in Zhengzhou, China, has got many national patents and international certifications such as IBR, ASME. We can be a good boiler manufacturer to both domestic and aboard markets. With more than 70 years history, ZG Boiler is confident to move further and faster on boiler technology innovation road.
Food Factory drum boiler water wall and its prevention package of food plant boiler water wall bulge causes and preventive measures? When the water wall tube localized corrosion occurs, the inner wall becomes rough, scaly easily formed in a relatively rough places, and then thickens. Local no good expanded metal soda mixture was cooled temperature, creep speed, and the tubes are not contaminated due to obtain good low-temperature cooling wall, creep does not occur. Water wall tube macro scale for local expansion properties. If you cut the pipe, it was discovered where the drum, the inner wall have been contaminated. Food plant boiler drum wall 1. Summary of the cooling water supply common cause unacceptable quality, contamination of impurities into the boiler heating surface. 2. Run the improper operation of the tube wall overtemperature. 3. flames sweep wall, resulting in long-term water wall tube overheating. The high temperature of the water wall, which makes the metal surface of the water wall had a great temperature gradient. If insufficient cooling capacity of the pipeline medium, the direct result of the water wall temperature is too high.
The use of central heating hot water boiler is the best choice for winter heating in northern China. Shanxi Province is located in Chang Darrow Heating Co., Ltd. mainly provides heating and post-service maintenance of heating equipment, heating clients involved in enterprises and institutions, office buildings, residential housing and a variety of commercial and other entertainment venues. With the wide blue sky covered Battle of the project, China's gradual increase in the proportion of heating for cleaning, heating, Ltd. Dalong Chang respond positively to the call of national policy, high pollution intensity wishing previously used, low thermal efficiency of coal-fired boiler to replace the traditional use hot water boiler clean fuel. After comparing many boiler manufacturers, choosing the optimal selection, determined and professional cooperation parties do fast boiler fuel boiler cleaning equipment. Providing a fast side 35 MW gas tube hot water boiler (SZS35-1.6-Y.Q) according to their actual needs.
