Description

Filling shaft heating furnace The known filling shaft heating furnaces mostly set the use of high quality and carbonising fuels advance if during a continuous fire should be achieved throughout the heating season.

In the case of the well-known filling shaft furnaces for gas-rich coals, mostly the entire contents of the hopper to glow through. The fol-. gen. are poor controllability, often insufficient combustion when the combustion air is throttled and not infrequently Smoldering gases also escape into the heated room.

To remedy these deficiencies is the purpose of the present, in the drawing depicted I? formation.

Fig.r shows the filling cliaclite furnace in section A.

Fig. 2 shows the furnace in section B.

Fig. 3 shows a diagram of the hopper cover and layout the 1? filling door for side loading.

Fig. D. shows the arrangement of the hopper cover and filling device with top loading.

The hopper a is in a known manner on the one hand by an in the stove built-in strong fireclay tongue against the combustion chamber and on the other separated by a tongue from a channel c, which is next to the feed chute of its the upper end leads to the space under the grate. The lower part of the hopper is bent towards the grate at the angle of slope for small pieces of coal. According to the invention, an inner flap b closes the hopper a. tight off. These The flap can either be opened outwards if the pivot point is at the bottom or can be folded up inside if the pivot point is at the top. This flap can also have a closable opening, so that the whole thing occasionally The contents of the hopper can be caught on fire quickly. The channel c begins above the flap b and leads into the space under the grate. The outer filling door d has one Air slide, by means of which the amount of combustion air supplied only at this point can be regulated. If the loading is to take place from above, then the loading door can cd can also be designed as a Klaplie, as Figure 4 shows.

The mode of action is as follows: As long as the inner flap b is tight is closed, the combustion takes place only on the grate surface and on the lower one End of the hopper. The ones that collect in the upper part of the hopper Smoldering gases prevent that the contact surface between embers and fuel moves up. Silence gases enter through leaks in the inner flap iii the upper part of the channel c, so these are together finite of the combustion air with simultaneous preheating under the grate, because it is at the top Position the = weakened chimney draft is fully effective. All other doors must be during of the company remain closed.

The advantages of this construction are: Achieving a slow, uninterrupted long-term burning with coal with a high carbon content and cheap coal; quality Controllability from smallest to largest heating output; completely odorless fire; no leakage of gases when falling.
