For solving the problems of the technologies described above, the utility model adopts a kind of so vertical end to combust the gas organic heat carrier furnace, comprises cylindrical shell, coil pipe and burner; The shell wall of described housing is provided with exhanst gas outlet, and described coil pipe is installed in the housing, and described burner is installed in the bottom downside of housing, is provided with a fire-resistant through hole in the bottom of described housing, and the port of described burner is connected with described fire-resistant through hole; The bottom of the contiguous housing of the exhanst gas outlet on the described housing shell wall.

As a kind of preferred embodiment of the present utility model, at the bottom of described housing downside the column that several are used for support housing is installed also, described coil pipe by interior, in, outer three circle rotation directions identical vertical type helical form coil pipes consist of, the two ends of described every circle helical form coil pipe respectively with being connected into and out of oily collector of this organic heat carrier furnace.

As another kind of preferred embodiment of the present utility model, also be provided with a circle helical form taper coil pipe on the top of described housing, the brickwork structure of this taper coil pipe and case top offsets.

The angle a of helical form taper coil pipe of the present utility model and horizontal plane is preferably 30 ~ 45 °.

In the utility model, described helical form taper coil pipe is arranged in vertical type helical form coil pipe top, described outer ring, and forms a whole with this outer ring vertical type helical form coil pipe.

After adopting said structure, the utlity model has following beneficial effect:

Because burner of the present utility model is installed in the bottom downside of housing, therefore again because most of fuel gas is less than atmospheric density, from the gas of the base burning climbing power by self, the burning resistance of flame is less, flame is longer, degree of filling is more even, and gas combustion is more abundant, and burns oxygen amount adjustment factor is sensitiveer, and reduced heat loss due to exhaust gas, improve the thermal efficiency, greatly reduced the generation of NOx, more be conducive to environmental protection.

Burner of the present utility model is installed in rear flank under the bottom of housing, being installed in case top with burner in the prior art compares, the utility model need to not arrange rain-proof shelter at the top of body of heater, need to above the boiler room, not equip the lifting cucurbit yet, reduced so on the one hand the height of boiler room, greatly reduce on the other hand cost of investment, and because burner is installed in the bottom, keep in repair convenient.

After the bottom scheme of the utility model employing with the contiguous housing of the exhanst gas outlet on the shell wall, so that the connection in cigarette, air channel reduces highly greatly, further reduced cost of investment.

Coil pipe of the present utility model adopt by interior, in, the identical vertical type helical form coil pipe of outer three circle rotation directions consists of, and adopts such structure, makes the distribution of design discharge more flexible.

Because the utility model arranges a circle helical form taper coil pipe on the top of housing, the brickwork structure of this taper coil pipe and case top offsets, therefore, this taper coil pipe can be used as radiation heating-surface, and make the structure of heat carrier furnace compacter, reduced material cost, and the brickwork structure of furnace roof is as the weak link of heat carrier furnace, after having adopted described taper coil pipe, the brickwork structure greatly reduces, and makes the temperature of furnace roof lower, and radiation loss is less, improve the whole efficiency of heat carrier furnace, greatly saved the energy.Because the taper coil pipe has supporting role to the brickwork structure, thereby has greatly prolonged the service life of brickwork structure, has improved the bulk life time of heat carrier furnace.

The angle a of helical form taper coil pipe of the present utility model and horizontal plane is preferably 30 ~ 45 °.When mounted, the taper coil pipe is arranged in vertical type helical form coil pipe top, outer ring, and forms a whole with outer ring vertical type helical form coil pipe and to be installed in the top of housing.Adopt such structure, make on the one hand the effect of taper coil pipe absorption top heat of high temperature better, can play better on the other hand the effect of supporting furnace roof brickwork structure.
