| Abstract: | In order to solve the problem of oxidation etch onto the copper pipes within employing area of steam turbine condenser caused by outdated manual addition of chemicals into boiler's feeding system in thermal power station, a PLC based automatic control system of chemicals addition for boiler water feeding is developed. Operation principle of this system, hardware configuration, and software design are all discussed here. |
