BURNER DEVICE FOR HEATING OF GASEOUS FLOW Russian patent published in 2020 - IPC F23D14/66 F02K3/08 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering. Burner device for heating of gaseous flow is located in channel, at that in device is uniformly installed many burner modules divided into peripheral and near-center burners, where to each module along separate main line fuel is supplied from at least one collector. At the inlet to each separate main line there is an adjusting jet limiting the fuel flow, and lines for peripheral and near-center burners are made with different degree of heat exchange of fuel with gaseous flow depending on removal of burner modules from channel walls and ratio of fuel and gaseous flow temperatures. Detachable block-heat exchanger is installed at collector inlet. Detachable block-heat exchanger installed at collector inlet is made in form of fuel heater. Detachable block-heat exchanger installed at collector inlet is made in form of fuel cooler.

EFFECT: invention makes it possible to take into account non-uniformity of the flow temperature field at the inlet of the burner device, possibility of adjusting the uniformity of temperature fields and to reduce the temperature gradient of the channel walls.
