摘要： An industrial furnace has at least one assembly formed by an extruder for extracting hot gas present in a given zone of the furnace, a water/gas heat exchanger for cooling the hot gas, and a reinjecting device for reinjecting the cooled gas into a zone of the furnace situated downstream from the zone from which the hot gas was extracted. First and second sampling devices sample the hot gas at points each situated upstream and downstream from a heat exchanger and two-port valves allowing the sampling to be performed. A regulating device regulates the respective pressures of the hot gas and the cooled gas downstream from the sampling devices. A three-port valve selects the hot gas or the cooled gas and applies it to a hygrometer. An operator is informed of the results of analyses performed by the hygrometer so that the operator may compare the degree of humidity of the hot gas and of the cooled gas for each of the heat exchangers.
