Abstract (en)
[origin: EP0015480A2] 1. Apparatus for maintaining constant the mixing ratio of gas and combustion air which are fed through separate conduits to a blast burner having a pressure measuring point in one of the conduits, a membrane operated pressure transformer connected to the pressure measuring point which receives its working medium from one of the two conduits and produces a proportional pressure corresponding to the measured pressure and having a constant pressure controller controlled by the proportional pressure in the other conduit, characterised in that the membrane (16) of the pressure transformer (1) is held in its position of equilibrium by a valve controlled pilot (20) which receives the working medium and applies the proportional pressure to the constant pressure controller (11).
