Boiler workshop of 1# boiler deaerator temperature using the manual adjustment, the adjustment way high temperature fluctuations, one aspect that affects boiler process stability, on the other hand, is not conducive to energy conservation, at the same time, remote manual control valves to hand operation, but also increase the labor intensity of operators and labor time. The temperature control is always a difficult problem to mediation, self regulating system, PID parameters are very difficult to adjust. The instrument workshop technical staff carefully thinking, repeated tests, finally explore the automatic control scheme of a set of effective temperature. Automatic regulating valve operation of boiler temperature, to ensure the safety and long period running, deaerator temperature stability and boiler at the same time, reduces the labor intensity, improve production efficiency, the temperature regulating valve automatic control field and a new way.
