DEVICE FOR HEATING PROCESS GAS IN A GAS DISTRIBUTION STATION Russian patent published in 2018 - IPC F23C15/00 F23C9/00 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. Device for heating process gas in gas distribution station comprises a heat exchanger with pipelines for supply and discharge of process gas and a heat generator with a pulsating combustion chamber in the combustion chamber and resonator pipes placed in a jacket with the supply and discharge of a heat carrier to the heat exchanger, a valve-mixing device for preparing a fuel mixture and a spark plug, as well as a unit for supplying gas to the combustion chamber, consisting of electromagnetic valves controlled by the gas temperature regulator at the outlet of the heat exchanger. Input part of the combustion chamber of the heat generator is made in the form of a diffuser with an opening angle of 40…120°, and an exhaust pipe is made in the form of an additional resonating device connected with the pulsating combustion chamber, consisting of a cylindrical chamber of dimensions L/D = 1.5…2.5, installed at the output of the resonator of the pulsating combustion chamber, where L, D – respectively, the length and diameter of the cylinder, and a resonator in the form of a pipe of the length of 10…12 of pipe diameters, wherein the additional resonating device is provided with a jacket for cooling by a circulating heat carrier, wherein the reactive-active silencer installed at the output of the additional resonating device is a continuation of the exhaust pipe.

EFFECT: invention provides a wider range of stable operation of the device for gas heating, increased reliability of the heat generator.
