Automation Control Method of Time-Varying in Heat Conduction Coefficient and Pure Steam Output Interference

Abstract:

The relation curve of the raw water flow and main steam pressure under different main stream temperature is established by off-line experiments and expert experiences. For the time-varying in heat conduction coefficient, which is resulted by scaling and so on, water level need to be detected by installing float level gauge in every effect, and the curve can be corrected according to water level, so effective separation space of gas and water is ensured to avoid dry or flood pot. Because medical water distiller need to provide pure steam, by detecting the output flow of pure steam, correct the curve and inhibit the interference of production process due to pure steam output, then the production process of distilled water can be finished by automatically controlling the adjustable valves of raw water flow and main stream pressure. The method will improve the robustness of heat conduction coefficient time-varying and pure steam output interference.
