Oil-heater control system - regulates oil supply dependent on room temp. and speed of exhaust-controlled fan

摘要

The oil heater has an evaporative burner, whose air supply is aided by a fan operated dependent on the draught in the chimney. The oil supply to the burner (2) is regulated dependent on room temperature and the speed of rotation of the fan (6), which is turn depends on the varying draught in the chimney. There can be an oil regulator (3) in the supply pipe, and a variable-speed motor (7) acting on the fan, while the regulator is controlled by a thermostat (4) measuring room temperature and comparing it with a predetermined value, and the motor by a differential-pressure emitter (8) measuring the draught. ADVANTAGE - Minimum fuel consumption and carbonic oxide emission.
