The beneficial effects of the utility model:
1, this utility model eliminates pipeline outer wall (furnace shell high-temperature flue gas pipeline and furnace shell low temperature
Flue) external thermal insulation, make furnace wall heat radiation convenient, convenient find in time, place meanwhile
There is localized hyperthermia and burns red in reason furnace wall；
2, liner raised platform around a well of the present utility model becomes plane, without leeward dead angle so that heat-resisting valve plate
It is heated evenly, is not susceptible to deformation, stabilizes belljar valve seal, it is ensured that belljar valve pair
The regulatory function of flue-gas temperature；
3, belljar valve horizontal pipeline refractory lining of the present utility model can stand low-temperature flue gas
(< 500 DEG C) wash away, extend belljar valve, the whole service life of pipeline；
4, the thickness of vertical duct liner is designed to equal to stove main body liner by this utility model
Thickness so that vertical duct liner can stand high temperature (> 1200 DEG C) sweep of gases, extend
Belljar valve, the whole service life of pipeline.
