FIELD: heat power engineering.
SUBSTANCE: device comprises units for measuring enthalpy from pressure and specific volume of steam determined, in turn, by pressure drop at the throttle washers mounted in the water and steam sections of the steam-water path of the boiler. The system for control of enthalpy comprises functional units for generating control signal of controllers of water and fuel supply from the signals of visible steam and water flow rates and from the signal of enthalpy from the device for measuring enthalpy.
EFFECT: enhanced accuracy and precision of control.
