Abstract

686,130. Mounting pulverulent fuel burners. WALTHER & CIE., AKT.-GES. June 29, 1950 [Jan. 2, 1950], No. 16276/50. Class 75(i) [Also in Groups XII and XIII] In a pulverulent-fuel radiation-heated boiler with slag-tap ash removal having burners which can be swung upwardly and downwardly on a horizontal axis, the superheated steam temperature and the slag temperature are regulated by automatically adjusting upper burner nozzles according to the temperature of the superheated steam and automatically adjusting lower burner nozzles in accordance with the ash temperature. As shown in Fig. 1 a boiler furnace is lined with water tubes b and is provided with groups of burners d<SP>1</SP>, d<SP>2</SP>, d<SP>3</SP> which are angularly adjustable about a horizontal axis and which discharge towards the centre of the combustion chamber so as to produce a whirling flame. Burner groups d' and d<SP>2</SP> are adjusted by mechanism k controlled by a device i responsive to the temperature of superheated steam drawn off from a superheater g. Burner groups d<SP>3</SP> are adjusted by mechanisms o actuated by a device m responsive to the temperature of the slag at the bottom of the furnace, so as to direct burning fuel on to the slag until the slagmelting temperature is reached, above which temperature the mechanism o is controlled by the device i. Specification 642,671, [Group XII], is referred to.
