VALVE-MIXING DEVICE OF PULSED COMBUSTION HEAT GENERATOR Russian patent published in 2019 - IPC F23C15/00 

FIELD: power engineering.

SUBSTANCE: valve-mixer device of pulsed combustion heat generator with combustion chamber in the form of cylindrical cavity closed by end wall with through hole on one side and open on the other side contains ignition device and two coaxially made cylinders, which ends by means of common flange are connected to combustion chamber closed end, at that in internal cylinder wall zipper row of dosing holes for fuel gas supply from external cylinder is made, which through hole in wall is communicated with fuel gas supply system through check valve, and hole for air supply from atmosphere through check valve and valve-mixing device into combustion chamber, as well as fan for supply of air into valve-mixer and combustion chamber at start of heat generator. Along axis of inner cylinder there is a rod of flame stabilizer, which swirler is located behind combustion chamber passage hole and forms with its end wall combustion zone, and ignition plug ignition device is installed in threaded hole of boss, welded to side walls of inner and outer cylinders of valve-mixing device in zone between zona a series of dosing openings and closed end wall of combustion chamber symmetrically relative to two closest adjacent dosing holes in wall of cylinder.

EFFECT: invention allows operation of the ignition device in the zone of low temperatures of the valve-mixer device.
