A power plant has a combustion chamber with a vessel (2) for a bed (7) of fluidisable material, and with tubes (8) for heating water ir producing steam. Connected to a conduit or a chimney (26) for conducting away combustion gases from the bed vessel, are indicator instruments (43, 44, 46) which shows the presence of the tracer substance added to the feed water, which substance on tube leakage flows out into the bed vessel (2) together with the feed water. |
