Abstract

The utility model relates to a heat exchanging coal saving stove with an adjustable flue. Heat dissipation fins and heat conducting strips are added on the outside circumference of the wall of a stove basin shell. The heat conducting strips and the outside circumference of the wall of a stove basin shell form a plurality of air convection heat dissipation channels which are divided by the heat dissipation fins. A flue adjusting and heat collecting jacket of which the jacket wall is provided with a smoke exhaust port is added in the stove basin shell. The outside circumference of the wall of the flue adjusting and heat collecting jacket and the inside circumference of the stove basin shell form an annular flue. The utility model can directly exhaust smoke to rapidly elevate stove temperature, and can exhaust smoke in heat exchange mode for the stove basin to efficiently exchange heat by rotating the heat collecting jacket. The utility model can reduce pollution in closed burning and heating mode. Secondary air is supplied with hot by air an ash box to support combustion and elevate stove temperature.

Description

Transfer the flue coal-saving stove

The utility model is a kind of home-use coal furnace.

At present, widely used family coal furnace, the elevated temperature heat of stove eye mouth directly with between the stove basin smoke evacuation open gate forms thermal convection current, heat energy in the stove eye is not fully used just enters chimney, so the thermal efficiency hangs down serious environment pollution again.

The purpose of this utility model provides a kind of when fire door high temperature, the high temperature convection current thermal energy conduction that forms in the stove basin is given the quick heat exchange of stove basin, when stove fire was not prosperous, the cross-ventilation that can accelerate in the stove eye was combustion-supporting again, efficient more fully, the energy-saving and environmental protection coal furnace of the burning that furnace temperature is raise fast.

Realization the utility model is: stove basin shell wall peripheral distribution has vertical radiating fin, the fin periphery is equipped with annular conducting strip, between annular conducting strip and stove basin shell outer wall, formation is by fin several cross-ventilation heat dissipation channels at interval, the flue thermal-arrest of accent cover is arranged in the stove basin shell, on the jacket wall of transferring flue thermal-arrest to overlap exhaust opening is arranged, be assemblied in the stove basin shell, between week, constitute the horizontal annular flue in thermal-arrest jacket wall periphery and the stove basin shell wall, stir the thermal-arrest cover that can horizontally rotate, can make the exhaust opening on the jacket wall, when stove fire is not prosperous, forward to over against the position of stove basin exhaust opening, make the fume centralized in the stove eye directly enter chimney, improve furnace temperature fast.When furnace temperature is high, forward to back to the position of stove basin exhaust opening, make in the annular flue and to form the high temperature advection heat and conduct to stove basin shell and radiating fin, make its heat radiation balanced by conducting strip, avoid hot-spot, the air convection channel that conducting strip and fin constitute can both be in the quick convection current of air each fin to dispel the heat.The secondary wind inleting tube of this stove is installed on the fire grate, utilizes heat in the following grey box of fire grate to improve the gas temperature of secondary air, makes that the secondary air combustion-supporting effect is better, furnace temperature is higher.

Owing to adopt such scheme, realized that coal furnace can improve furnace temperature fast when low temperature, make fired coal combustion more abundant, stove basin energy high efficient heat exchanging when furnace temperature is high, can seal the burning heating, improve heat utilization efficiency, reduced coal consumption, reduced environmental pollution, use more convenient.

Below in conjunction with Fu Tu and embodiment the utility model is further specified;

Symbol figure is a facade sectional structure chart of transferring flue coal-saving stove embodiment.

1. stove basin shells 2. are transferred flue thermal-arrests to overlap 3. thermal-arrests cover exhaust opening, 4. stove basin radiating fins, 5. conducting strips, 6. fire grates, 7. secondary wind inleting tubes, 8. remains of fireboxs, 9. fireproof casings, 10. secondary air separating gas dishes, 11. stove basin exhaust openings, 12. stove basin decorative covers, 13. stove basins to cover 14. body of heater shells, 15. annular flue 16. air convection channel among the figure

In the figure illustrated embodiment, transfer flue thermal-arrest cover (2) to be assemblied in the stove basin shell (1), transferring the Nei Yuan hole and the stove eye of flue thermal-arrest cover (2) is with the garden heart, constitute horizontal annular flue (15) between jacket wall periphery and the stove basin shell inwall, thermal-arrest cover exhaust opening (3) is arranged on the jacket wall of accent flue thermal-arrest cover (2), rotate the position of thermal-arrest cover (2) adjustable disaggregation hot jacket exhaust opening (3) on horizontal annular flue (15).Stove basin shell (1) wall peripheral distribution has vertical radiating fin (4), and the outer garden week assembling conducting strip (5) of radiating fin constitutes air convection channel (16) with stove basin shell (1).Secondary wind inleting tube (7) is assemblied on the interior fire grate (6) of body of heater shell (14), and secondary wind inleting tube (7) is suitable for reading to fireproof casing (9), and it is combustion-supporting to supply with firehole mouth hot blast by the gas port of branch of institute on the secondary air separating gas dish (10).Be bell circle (12) between week in thermal-arrest cover (2) periphery suitable for reading and stove basin shell (1) are suitable for reading, Lu Pengai (13) is opening in diagram, to represent the internal structure of stove basin.

Claims
