PCT No. PCT/SE92/00582 Sec. 371 Date Mar. 11, 1994 Sec. 102(e) Date Mar. 11, 1994 PCT Filed Aug. 25, 1992 PCT Pub. No. WO93/06416 PCT Pub. Date Apr. 1, 1993.A method and a device for temperature measurement of the fluid at the outlet from an evaporator in a boiler of benson type, wherein the evaporator includes one or more inlet headers which are supplied with water passed on to evaporator tubes which communicate with a heat-transferring medium and wherein the water is transformed into a fluid which is then via evaporator stubs passed to one or more outlet headers of the evaporator, the temperature of the fluid being measured with the aid of temperature sensors which are placed on adjacently located evaporator stubs for a number of important and critical parts of the boiler, the measured values for each part being supplied to median value selectors whereafter each median value is supplied to a maximum selector, whereby the maximum temperature (tmax) of any of the outlets from the evaporator is obtained, and to a means temperature (tmean) of the fluid at the outlet of the evaporator is obtained. |
