Title:
CONTROL METHOD IN VAPOR DISTRIBUTION SYSTEM
Document Type and Number:
Japanese Patent JPH01320514
Kind Code:
A
Abstract:
PURPOSE:To attain labor saving, the reduction of vapor loss, and the stable operation of a vapor system by selecting a control mode decided in advance fitting in each monitoring point of the vapor system, a load on a vapor supply side, and the status of a user side, and performing automatic adjustment on the exit vapor flow rate of a supply facility. CONSTITUTION:The monitoring points (N1-N3) of vapor pressure, etc., are provided at pipes to plural vapor using facilities (21-23) from the vapor supply facility such as an accumulator 11, a back pressure turbine 12, and a blast boiler 13, etc. A controller 3 compares pressure values from those monitoring points with a reference value set separately, and decides the control mode based on a pressure trend and the use schedule information of the vapor using facility, and also, and the flow rate preset value of each supply facility is found by a prescribed equation by judging the status of a distribution system from the load condition of the supply facility and the fluctuation of a quantity in use at the vapor using facility side, thereby, the vapor exit flow rate of each supply facility is controlled and the fluctuation of pressure at each monitoring point can be controlled within tolerance.
