DOUBLE-STAGE GAS BURNER Russian patent published in 2009 - IPC F23N1/00 F23D14/60 

FIELD: heat-and-power engineering.

SUBSTANCE: invention relates to energetics, particularly to double-stage gas burner and can be used for burning of gaseous fuel in boiler of outside placement and other gas apparatus, located on air. Double-stage gas burner contains control unit of two-position shutter, sensor of temperature, draw, flame, supply-line gas, fire button with igniter and fire box, valve, main burner, nozzle of two-position shutter, switch, thermobimetallic plate. Burner is outfitted by automatic power controller, installed consistent before adjusting device in environment, containing in partition of body opening for gas discharge in volume 30-40% of maximal consumption, can also containing valve land with valve, implemented with ability of regulation of manometric system, increasing consumption of gas up to maximal at decrease of environment temperature.

EFFECT: invention provides simplification of design, reduction of overall dimensions.
