high pressure sugar mill boilers vietnam

Liquefied natural gas is one of the commonly used fuel gas high pressure sugar mill boilers vietnams, liquid natural gas mined state after compression treatment rendered, whether it is transportation or use are very convenient and safe.

Application Class A high pressure sugar mill boilers vietnam manufacturing qualification to have what the basic requirements: A class boiler manufacturing license acquisition conditions are more demanding, which is why there is still a lot of B, C-class boiler manufacturers. As a large industrial boilers and power plant boiler manufacturers, Zheng pot history of 70 years, more experienced multiple A-class replacement, at the time of grinding the self-rising, has become an important export enterprises boiler.

In the process of cooperation with Lulu, the company has maintained a serious and responsible attitude and enthusiasm, any after-sales problems in a timely manner to communicate and resolve site or through the network. Lulu's relevant person in charge to give us feedback, we buy fast high pressure sugar mill boilers vietnam is not only fast because of strong party strength, but also because of the powerful party fast service, any improper operation can get our phone to remind party fast remote monitoring, this allows us to use very reassuring. --customer feedback

Boiler start-up process, the drum, the lower wall temperature difference is how to generate? During start-up, the drum wall absorbs heat from the working fluid, the temperature gradually increased. Start early, high pressure sugar mill boilers vietnam water circulation has not been correctly set up, the drum water is not flowing state, convection heat transfer coefficient of the wall of the drum is very small, i.e. very slow heating. An upper drum into contact with saturated steam at elevated process pressure, a portion of the vapor will condense adherent, exothermic condensation of the metal walls of the drum, which convective heat transfer coefficient than the lower aqueous many times higher. When the pressure rises, the upper wall of the drum can be relatively close to the saturation temperature corresponding to the pressure, while the bottom wall is raised very slowly. Thus formed on the drum wall temperature is high, the low temperature condition lower wall. Boiler boost faster, the larger the temperature difference between the lower wall. On the drum, the temperature difference of the lower wall, the upper wall of the drum by the compressive stress, tensile stress by the lower wall. Large temperature difference, the greater the stress, the drum tends to cause severe shape deformation of the extrados. To this end, China's relevant rules of order: the drum, the lower wall allows the temperature difference is 40 ℃, the maximum does not exceed 50 ℃.
