If fuels containing comparatively little slack and low in ash are to be used, a fixed grate which admits of drawing clinker and ashes at any time is put in. The ash pits are closed by plain doors and slides. The hot refuse remains in the ash pit or on the grate until all its available heat has been used to preheat the air supply and to generate additional steam. Afterwards it is removed in ash trucks. If a plant is to be used for simultaneously producing gas for heating and for power, it has two separate gas mains and gas exhausters. No charging is done while the chambers are working in the order in which they were ignited. The chambers are suitably connected with each other through the central flue, and the injector draws the steam and the tar-containing gases of the later kindled producers through the previously kindled producers, which are connected to the gas main. At the same time the air supply, mixed with steam and heated by the refuse in the ash pit and on the grate, is sucked into the chambers at the bottom. According to the scheme outlined above, the process of gas production in the Julins "ring" producer is divided normally into two stages, as follows: (a) Gas expulsion or distillation, which may be called the preparatory stage. (6) Gasification. In the multichamber producer the duration of the preparatory stage is only a fraction of that of the gasification stage. In a "ring"' generator, therefore, several chambers may be prepared one after the other during the gasification period of one chamber--Fioum 2.--J alms " ring " producer at the Von der Heydt royal colliery, near Saarbriicken, Germany. in a three-chamber...
