Method of watching function of condenser

Abstract

Abstract PURPOSE: To detect malfunction of the condenser in earlier stage and accurately by detecting the coding water outlet and inlet temperature of the condenser, the cooling water quantity and the temperature within the condenser to compute the heat transfer rate or the tube cleaning degree and watch the function of the condenser. CONSTITUTION: A condenser 3 with respect to a steam turbine 1 and a generator 2 comprises a water supply pipe 8, a water exhaust pipe 9 and a cooling pipe 13. A continuous cleaning device consisting of an arrester 4, a pump 5, a recovering apparatus 6 and a distributor 7, is connected to the condenser 3, and cleaning balls 12 are circulated. A pressure senser 18 is provided in the trunk body of the condenser 3, and temperature sensers 19 and 20 and temperatue difference sensers 21 and 22 are provided in the water supply pipe 8 and water exhaust pipe 9, respectively. Ultrasonic wave sensers 23 and 24 are installed in the water supply pipe 8 in a confronting manner to constitute a ultrasonic wave flowmeter. Furthermore, a plurality of hot flow sensers 25 are installed on the surface of the cooling pipe 13. From the measured values of these sensers, the heat transfer rate or the tube cleaning degree is computed, and the computed value is compared with the set value. COPYRIGHT: (C)1981,JPO&Japio
