FIELD: machine building.
SUBSTANCE: method of detecting at least partial sealing of hollow partition wall (6) of multichamber furnace (1) with rotating flame with chambers (2) involves the stages, at which there determined is variable Rx characterising the flue gas flow in hollow partition wall (6) of serial number x among partition walls (6) of chamber (2) of furnace (1); there determined is reliability interval of set of variables R at least of several partition walls (6) of serial number from 1 to n specified chamber (2), excluding Rx, based on average value m and typical deviation σ of the above variables R; there shall be checked at subsequent moments and preferably continuously, whether variable Rx is beyond the limits of the specified reliability interval or not; at that, only as per lower value, and in case of positive result there supplied is alarm signal indicating at least partial plugging of hollow partition wall (6) in line of partition walls (6), to which the above partition wall (6) of serial number x belongs, relative to other partition walls (6), and/or command is supplied at least for single change of control of furnace (1) operation.
EFFECT: improving the detection reliability of plugging of hollow partition wall.
