The inner side of the insulating outer cylinder wall 1 is connected to the heat-conducting inner cylinder wall 2. The heat-conducting inner cylinder wall 2 is made of heat-conducting metal. The insulating outer cylinder wall 1 is made of heat-insulating material to reduce heat loss. A plurality of heat-conducting plates 3 are connected to the heat-conducting inner cylinder wall 2. The heat-conducting plates 3 are each provided with a plurality of heat-conducting holes for full contact with the flue gas.

The right side of the middle part of the insulating outer cylinder wall 1 is connected to the temperature sensor 4.
[0018] When using the present invention, the heat-insulating outer tube wall 1 is first installed in the use area of the chimney. During use, the flue gas will be filtered by the filter 8, and the harmful particles or impurities in the flue gas will be filtered out before entering the heat-conducting inner tube wall 2.
