Title
(EN) Hydraulic actuator for chimney damper of oil fired heating unit
(SV) ANORDNING FOR STYRNING AV EN SPJELLREGULATOR VID VERMEPANNOR
Abstract
(EN) The opening of the chimney damper in an oil fired heating furnace is controlled by a hydraulic cylinder acting against a spring to open the damper. The hydraulic cylinder is supplied through a hydraulic line from a power cylinder using a non-flammable working fluid. The power cylinder has a free piston with the non-flammable fluid above and oil from the burner oil pump below. The burner oil pump is motor driven from the electrical mains through a regulator and draws oil from a tank, delivering the oil to a burner and to the damper power cylinder. Oil is taken away from the power cylinder by a valve operated by the thermostat for the heater. The thermostat and a pyrostat control the operation of the oil pump motor.
