Abstract (en)
[origin: EP0060345A2] In heating boilers (1) fired with oil or gas, air should be added to the flue gases to prevent condensate separation in the chimney (3). For this purpose, an air duct (7) is attached to the flue duct (6). Furthermore, means are provided for feeding air into the flue gas stream, namely a constriction (5) of the flue gas duct (6) upstream of the air inlet or an air injection impeller (11) in the air duct (7). In particular, the air injection impeller (11) should be controlled by a temperature sensor (9) in the flue gas stream so that air is added below a specified flue gas temperature. <IMAGE>
