There are three kinds of cycle chemistry in boiler water to adjust boiler's water pH value in thermal power station. The generall calculating model for boiler's water pH value is obtained through chemical equilibrium equation and mathematical deduction in the paper and the results of boiler's water pH value is given in graphics and validated by practice data of boiler cycle chemistry. The generall calculating model can be used to check up and forecast the changing trend of boiler's water pH value,and helps to take optimum measure in boiler cycle chemistry. The calculation results of boiler's w...
