FIELD: heating.
SUBSTANCE: mechanism for control of air flow in furnace comprises body 1 with zone of burning 2, where there are channels arranged for air supply 3, 4 into zone of burning 2 so that their one part continuously connects zone of burning 2 to environment, and the other one, additional one, 4 - is arranged with the possibility of their coverage, exhaust pipe 10, door 8 in body 1. Besides mechanism is arranged in the form of profiled lever 11, installed with the possibility of swinging in furnace body 1. One end of lever 11 is arranged in zone of fuel location and interacts with it, and the other one is kinematically connected to shutter 14, which isolates additional channel 4 of air supply into zone of burning.
EFFECT: reduced consumption of furnace fuel.
