To keep the boiler water with a PO 3- 4concentration at 0.3～1.0 mg/L and pH values between 9.0～9.7 will play a ve ry good role in the prevention of the metal corrosion . This method can improve the quality of water and steam , reduce the scale deposit on heated surface.
In addition, the calculation results are shown graphically. Meanwhile, the impact of the presence of acidic foreign matter, such as H_2CO_3 and CH_3COOH on the pH value of boiler water was calculated and analyzed.
Industrial boiler water supply system designed based on microprocessor MCF5272 is presented . With the hardware platform integration with software, and combination with WISM02C wireless communication module, the system has been applied in the building of industrial boiler water supply controlling system for many middle and little enterprises.
The experimental study on treatment process of vapour driving oil recovery wastewater reused for high pressure boiler water supply was presented, and the disposal effects of several treatment processes of vapour driving oil recovery wastewater reused for high pressure boiler water supply were analysed.
It was concluded that steels susceptible to intergranular corrosion should not be used in contact with boiler water and chloride solutions.
A method for determining coefficients of distribution of contaminants between boiler water and steam generated in boilers and steam generators of nuclear power plants, which is based on standard thermodynamic dissociation constants, is presented.
At equivalent continuous bleeding this design ensures minimum consumption of alkaline-phosphate mixture introduced for conditioning the boiler water and minimum salt content.
