Abstract

Procédé de régulation d’une installation de combustion, ainsi qu’installation de combustion correspondante Dans ce procédé de régulation, des combustibles solides (C) sont introduits dans une chambre de combustion (10) d’une installation de combustion, de l’air primaire (P) est introduit dans une partie basse (10A) de la chambre de combustion pour y opérer une combustion primaire des combustibles solides, et de l’air secondaire (S) est introduit dans une partie haute (10B) de la chambre de combustion pour y opérer une combustion secondaire de gaz (G) issus de la combustion primaire. Afin de maîtriser la combustion secondaire opérée dans cette installation, la température de la combustion secondaire est mesurée dans la partie haute de la chambre de combustion par un ou plusieurs pyromètres optiques (60.1 à 60.5) qui sont agencés latéralement à la chambre de combustion, et le débit de l’air secondaire est commandé en fonction des mesures du ou des pyromètres. Figure pour l'abrégé : Figure 1Method for regulating a combustion plant, as well as corresponding combustion plant In this method for regulating solid fuels (C) are introduced into a combustion chamber (10) of a combustion plant, air primary air (P) is introduced into a lower part (10A) of the combustion chamber to perform primary combustion of solid fuels therein, and secondary air (S) is introduced into an upper part (10B) of the combustion chamber. combustion to carry out a secondary combustion therein of gas (G) resulting from the primary combustion. In order to control the secondary combustion carried out in this installation, the temperature of the secondary combustion is measured in the upper part of the combustion chamber by one or more optical pyrometers (60.1 to 60.5) which are arranged laterally to the combustion chamber, and the flow rate of the secondary air is controlled according to the measurements of the pyrometer(s).
