IGNITION BURNER Russian patent published in 2014 - IPC F23D14/00 F23N5/04 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering, in particular, to ignition burners in devices for combustion of gaseous fuel. The ignition burner comprises a body, on which a thermobimetallic plate 2 is fixed, at the same time on the body there is a sensor 3 of pipeline gas with a normally closed nozzle, and an igniter, and the pneumatic circuit of the ignition burner comprises a gas valve 5, a control and regulation channel 6, temperature sensors 7, a draught sensor 8, the main burner 9, the pipeline sensor 3, a tap 10, an ignition burner 11 with a thermobimetallic plate 2, at the same time the gas valve 5 comprises a seat 12 of the valve 5, an elastic element 13, an under-membrane space 14, a membrane 15, the sensor of pipeline gas 3 comprises additionally installed an elastic valve 16 with an axis 17 and a spring 18, to move the thermobimetallic plate 2 as the flame of the ignition burner 11 goes off, at the same time all elements of the pneumatic circuit are connected by pulse tubes.

EFFECT: invention is aimed at reduction of time of actuation of a pipeline gas sensor, its increased reliability and safety during operation.
