Description

FIG. 1 of the drawing shows a longitudinal section of the proposed furnace and FIG. 2 is the same modified firebox.

The proposed firebox (Fig. 1) consists of a retort (in the form of a rotating cylinder closed at both ends, into which fuel (slate) is introduced through the front cover from the funnel 2 to heat it without air access for the purpose of evolving volatile products from the shale. In order for the slate to be retrofitted, it is the latter when it turns into a rotary motion, similar to cement rotary kilns. Solids by dry distillation are small, i.e.; coke or semi-coke are removed from the retort through slots 3 to generator #. The products of the latter are discharged into the chamber 7 for heating the retort and their subsequent direction (under the influence of draft), together with gaseous products leaving through the slots of the 3 retorts, into the chamber 5 under the combustion boiler, with a corresponding flow of air. The generator 4 is made in the form of a cylindrical vertical mandrel, the bottom of which is closed by one or another device for removing garbage from the generator. If this garbage is solid, it will be some sort of crushing device. If. waste will be liquid, then it will be just Vs..nna with litiny; about 1, like a cupola. The air in the generator shaft is supplied by a fan through tuyeres, while this air can be cold or heated, depending on from the bridge, whether they want to drive the generator in a cold or hot process. The walls of the generator can be cooled with water or air in order to prevent slag from sticking to them, since such sticking will inhibit the even downward movement of the internal contents of the generator. The oxygen required for the combustion of gases is introduced through special adjustable openings in the rear part of the furnace under the roof covering the chambers / gasification, or in:
