FIELD: power industry. ^ SUBSTANCE: in the device there is provided gas temperature sensor, output signals of which are supplied back to gas temperature control assembly which in its turn is connected to the heating assembly with possibility of temperature control of gas leaving the heating assembly. Heating assembly is made in the form of electrically conducting cover or cavity through which gas or gas mixture is directly passed, and control is performed. In such case to the cover there supplied is the voltage controlled by means of control assembly in electric circuit; at that, owing to the current flowing in the circuit and material resistance the cover is heated, and as a result of which the gas or gas mixture is heated, after that gas temperature is measured and measurement results are supplied back to control assembly for control of voltage in compliance with gas temperature required at the outlet of cover or cavity. ^ EFFECT: invention allows accelerating the obtaining process of hot gas. ^ 14 cl, 3 dwg |
