Ring casing 16, is the second vane room 15 between the outer air duct 6 and interior air duct 4, is third between the interior air duct 4 and combustion chamber 2
Vane room 14, first vane room 16 are connected to the second vane room 15, second vane room 15 and third vane room
14 connections；
Ventilating smoke tube 5 is equipped in second vane room 15, the lower end of the combustion chamber 2 passes through lower flue room 3 and ventilating smoke tube 5
Lower end connection, the upper end of the ventilating smoke tube 5 is connected to upper flue room 7, and the upper flue room 7 is connected to chimney 10；
The outer housing 12 is equipped with air inlet, and the air inlet is connected to the first vane room 16, the outer housing 12
Side wall is equipped with air outlet, and the air outlet 13 is connected to third vane room 14.
Further, the lower end of first vane room 16 is connected to the lower end of the second vane room 15, second vane room
15 upper end is connected to the upper end of third vane room 14；
The upper end of the outer housing 12 is equipped with air inlet, is formed against the wind between the outer housing 12 and the upper flue room 7
Room 8, the air inlet are connected to by room 8 against the wind with the upper end of the first vane room 16, and the side wall of the outer housing 12 is equipped with out
Air port 13, the air outlet 13 are connected to the lower end of third vane room 14.
