CONTROL DEVICE FOR GAS SUPPLY TO PEAK HEAT SOURCE OF DISTRICT HEAT SUPPLY SYSTEM Russian patent published in 2014 - IPC F24D3/00 

FIELD: heating.

SUBSTANCE: control device for gas supply to the peak heat source comprises the first temperature sensor mounted on the output of the peak heat source that measures the temperature of the coolant, the second outdoor air temperature sensor, a gas supply regulator and the main controller, which inputs are connected to the said temperature sensors, and the output is connected to the gas supply regulator. The third coolant temperature sensor is mounted at the input of the heat exchanger from the side of the central pipeline, at that the main controller comprises a calculator, a rapid response unit, and a control unit of the gas supply regulator. The inputs of the calculator are connected to the outputs of the first and second temperature sensors, and its outputs - to the inputs of the rapid response unit, the outputs of which are connected to the third input of the calculator and the input of the control unit of the gas supply regulator, and the second input of which is connected to the output of the third temperature sensor, and the output of the second temperature sensor is connected to the additional input of the rapid response unit, and the rapid response unit is made in the form of a fuzzy model.

EFFECT: improvement of the accuracy of regulation of the coolant heating process , the temperature stability.
