FIELD: power industry. ^ SUBSTANCE: door 1 of combustion chamber 2 of furnace includes inner 3 and outer 4 walls. Partitions 5 are located between walls 3 and 4 to divide the space between walls 3 and 4 into channels of rectangular cross-section. On upper edge of the door the channels have holes 7 mating, when the door is in closed position, with channel 8 one of walls 9 of which is made as an integral part of wall of furnace combustion chamber 2. On lower edge of the door the channels have holes 10 which allow the air to be supplied to combustion chamber 2. ^ EFFECT: invention allows improving heat insulation and reducing power losses during fuel combustion. ^ 4 cl, 2 dwg |
