Title: Coal-fired boiler fuel supply control - for hot water heating system, with only one charge level sensor
Inventor: SCHUETZ DIETLEF DIPL ING
IPC: F24B13/04
Filed: 1974-05-10
Abstract: Apparatus for automatic control of supply of coal to a hopper comprises a charge level sensor which cuts off supply on reaching the upper limit. A time switch is released when the sensor responds or when it returns to the non-operating operating position after responding, and switches on the supply again after an adjustable period of time. The adjuster member of the time switch is controlled by e.g. the air valve, so that supply is switched on again before charge level reaches a lower limit. The drawing shows a bistable trigger stage for neutralising any contact rebounds and forming the flanks of the potential curves, an AND member, an npn transistor, and a relay which actuates two thyristors arranged in countercurrent in the circuit of an a.c. pump motor for coal supply.
