boiler in nigeriapplied to food factory
The main factors restricting shutdown cooling rate, after the shutdown drum may not cause excessive thermal stress. Steam oven with steam and heated water to the drum contrast, after shutdown due to an external insulation with a drum, the drum wall temperature drop is slower than the saturation temperature decrease rate of the steam and boiler in nigeriapplied to food factory water, is boosted and the upper portion of the ignition the lower portion of the boiler water cooling drum wall. Due to the large drum boiler water wall heat transfer coefficient, the lower half of the drum wall temperature decreased rapidly, while the saturated steam into superheated steam heating in the upper half of the drum. Superheated steam only a very small thermal conductivity, but also because he and the steam temperature is higher than the temperature, density, and natural convection can not be saturated steam is smaller than the saturated vapor. Therefore, the heat transfer coefficient on the wall of the steam drum is small, the temperature of the upper half of the drum decreases slowly. On the drum, the lower half of bananas due to temperature difference occurs upwardly formed deformation thermal stress.
After the project identification, party fast technical staff soon made contact with our company, to our installation, commissioning, to ensure the look normal, stable use during boiler in nigeriapplied to food factory operation. Thanks fast boiler professional technical support and good service, I provide a lot of help for the textile dyeing and finishing production company. --customer feedback
Boiler installation before you need to do preparatory work boiler in nigeriapplied to food factory to provide steam and hot water for daily life or industrial production equipment, after the purchase of a good business model will need to consider boiler installation, boiler installation is directly related to the smooth functioning of important boiler step, in addition to a host of auxiliary installation, also need to pay attention to the preparatory work before installation. 1, for gas boiler installation Registration: According to the "Steam Boiler Safety Supervision Regulations" provides boiler units should use one by one to register. Boiler unit boiler installation work should be specifically responsible, responsible to get in touch with the local supervisory bodies boiler, installation fill this book. Fireman when they need to participate in the boiler installation, and with a plumber, fitter, rigger, cold work, and welders and helpers. 2, to determine the qualifications of boiler installation site and determine the installation location, boiler installation unit must be installed in line with qualifications boiler installation range of the higher authorities issued. 3, check the boiler and accessories: front, gas-fired boiler installation works deal with combustion equipment, parts, boiler auxiliary natural gas, inspection and acceptance by drawing attachment, make a record, is found not to comply with the relevant standards should be made to the factory . Preparation of boiler installation and construction is particularly critical, adequate preparation boiler is the fundamental guarantee smooth production standards, preparatory work for a successful conclusion to this part of the work is closely related to each stage inseparable.
Application Class A boiler in nigeriapplied to food factory 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.
