Abstract

797,453. Draught stabilizers for Hues. TRIANCO, Ltd. Feb. 15, 1957 [Feb. 16, 1956], No. 4907/56. Class 51 (1). A boiler flue has an air inlet port 2 controlled by a counterweighted pivoted flap 1 which closes the port during normal operation of the boiler but is adapted to open when the pressure in the flue falls below a certain value when the boiler is idling. The flap is held closed by a spring blade 8 mounted on a pivot 15 and held by an electromagnet 16 in circuit with the motor of a forced draught fan so that its end 9 bears on a roller 6 on an arm 5 attached to the flap. The flue is fitted with a pivoted safety valve or plate 20 held closed by an arm pivoted on the plate and loaded by an adjustable weight 28.
