to discharge the carbonization gases.

Patented in the German Empire on May 31, 1923 ah.

The invention has a long-life stove for inferior, queasy fuels (Brown coal, coke breeze, green coke) to the object in which the filling shaft of a Jacket channel is surrounded to discharge the carbonization gases.

The aim when building such ovens is to use half-gas firing as far as possible to use highly heated additional air. So far has been the warming of the fresh air mostly made in places; which is better used for heat exchange to the outside would. According to the invention, the preheating channel for the additional air is by way of the grate gases around the lower end of the filling shaft sheathed smoldering gas duct relocated.

The drawing shows an embodiment of such a furnace.

Fig. Ι shows a vertical section ao through 'the furnace,

Fig. 2 a horizontal section just above the grate,

Fig. 3 is a bottom view.

The arrangement is made such that a double-walled bell is formed α , the one

uniform heating of the carbonization gases that are drawn down and also heating of the second fresh air flowing through the ring duct b.
The heated smoldering gases and the highly heated second fresh air combine at the outlet of their supply channels a _lt b _lt ignite on the grate flames in the combustion chamber c and get into the with them

ίο Heating room d, in which the gases rise and give off their heat to the outside and inside to the additional air duct b .

Furthermore, the heat inside the bell dries the fuel on which further way down, partially degassed to burn last.

The smoldering gases heat up on the wall of the bell and are when they exit burned with the additional air.

Claims (1)

P ATENT claim: Long-term burning furnace for inferior, uncomfortable fuels with a filling shaft jacket to discharge the carbonization gases, characterized in that the lower part of the jacket channel (a) which conducts the carbonization gases to the furnace is adjacent to an annular channel (b) for additional heated air, which is coaxial with the ring slot (b ¹ ) Muzzle slot (α ¹ ) of the jacket channel (α) opens.
