DOUBLE-STAGE AIR COMPOUND GAS BURNER Russian patent published in 2008 - IPC F23D14/60 F23N5/24 

FIELD: engineering industry; double-stage air compound gas burner.

SUBSTANCE: double-stage air compound gas burner includes parallel combined gas changers of the first and second step. Each of them consists of control block, run button, screen with hard central point, seated valve, upper space, two-position damper, drainage nipple and nipple of pressure source, low-regulating valve with channel, flame rods, two valves, burners with flame igniter, three heating controllers with particular sensors, and diaphragm switch. Burner is also provided with the ventilation unit with directing pan and auto air valves, magnetic coil, voltage sensor, and microswitch. Herein control block of the second step is connected to the space of diaphragm switch with the possibility of microswitch 'turning on / turning off'. Latter is connected with ventilation engine while switch space is connected with voltage sensor, and ventilation is connected to the directing pan situated under the burner. Directing pan contains the auto axle-mounted air valves.

EFFECT: power ascension; gas burner cheapening; gas burner design simplification.
