Flue, that is, the inner tube of inner chamber cylinder, be allowed to carry out first time heat exchange with this heating part of inner chamber cylinder and water therein and
Heating, when flame soot mixed flow reaches center flue upper port, under suction function, turn back into inner chamber cylinder, exocoel cylinder institute
The cyclone channel surrounded, it is spiral to decline, second of heat exchange is carried out with inner chamber cylinder, makes the heat of flame soot mixed flow further
The water in the cylinder of inner chamber is passed to, its temperature is further raised, while is also heated the water in exocoel cylinder, flame soot mixed flow
Just drain after going out cyclone channel into chimney, thus greatly extend flow time of the flame soot mixed flow in stove,
Heat is sufficiently absorbed, and boiler is heated up water or the efficiency of water vapour is naturally higher.
Tornado flow in the flue of center can be that the interior spiral plate that sets is formed, and can more pass through the tangent line side at the top of the flue of center
To whirlwind mouth, allow mixed flow with tangential direction enter cyclone channel and formed.
Due to toward enough air have been blasted in furnace, having not enough time to burn or insufficient thin buckwheat coal that burns be in whirlwind
There are enough chances further to burn in passage so that the heat of burning is more fully discharged.
Therefore, the method for this whirlwind heat exchange of the present invention, enables the mixed flow of flame, flue gas and grit same to boiler
Heated device is repeatedly heated, and fuel is fully burned, and the thermal efficiency is higher, and the time of burning in boiler steam is shorter, more saves coal, discharge
It is cleaner.
The cloth bag effectively collecting solid hazardous grit again that gathers dust is set on chimney breast, reduced to atmospheric environment
Pollution.
