Abstract:
A high level of oxygen in boiler supply water would lead to oxidation corrosion of the boiler tubes. Reduction of the boiler tube thickness will affect its service life even result in such serious accidents as tube explosion. In S oil-field, a combining measure of physical and chemical methods were adopted to improve deaerator technology. A relatively complete ground deaeration process is formed. The deaeration system consists of water ring vaccum pump, deaeration tank, booster pump, circulating tank, etc. First softened water processed by softener would flow through 80 mesh stainless steel sc

Abstract:
The reliable and economical operation of equipment for thermal power plants, heat supply systems and boiler houses has been a relevant problem in the field of thermal power engineering for many years. In many industries, industrial steam is often used, for which steam boilers are used at thermal power plants. The water consumed by the boilers undergoes pre-treatment, which, in addition to its softening, includes thermal deaeration — the removal of aggressive gases that lead to equipment corrosion. Atmospheric deaerators are often used for this purpose. They are easy to use, quite effective, bu

The gas bubbles affect the properties of the pulp suspension, reduce the accuracy of certain measurements, interfere with the runability of the papermachine and detract from the quality of the end-product.
