FIELD: heat power engineering.
SUBSTANCE: invention relates to heat power engineering, namely to power control systems for solid fuel heating boilers, and can be used to create non-volatile heating boilers with a high-precision mechanical heat power control system. A device for controlling the thermal power of a solid fuel boiler, containing an inlet air duct, a two-stage damper, a damper actuator, a thermostat connected through a actuator to the damper, a boiler jacket, a return pipeline branch pipe, contains a limiter, a tube and a reflector placed in series inside the boiler jacket, between the thermostat and the return pipe pipeline.
EFFECT: increasing the accuracy of dynamic control of the thermal power of a solid fuel boiler due to the high accuracy of control of the inlet air flow and the short response time to instabilities that occur in the boiler or heating system.
