Abstract

1446785 Rotary boilers FINVENTA-HOLDING AG 23 Nov 1973 [23 Nov 1972] 54433/73 Heading F4A [Also in Division F1] In a rotary boiler for a thermodynamic machine such as a heat pump or an expansion motor a rotatable assembly of tubes 2 is arranged in a generally axial direction with respect to the axis of the boiler, each tube 2 having a series of annular externally conductive spaced fins 21 and the tubes 2 being collectively connected by a rotatable header drum 3 to receive liquid therefrom, a connection 52 being provided to a receiver drum 5. Each tube 2 is provided with a weir or barrier 50 to retain, in operation, liquid 49 in each tube and the rate of liquid supply in relation to the rate of evaporation in the tubes is controlled to ensure that the amount of liquid in the tubes is always sufficient to result in a flow over the weir or barrier. A burner 36 is arranged within the ring of tubes 2 and cooling fins 26 are provided on tubes 34 leading from the receiver drum 5 in the condenser portion 6. Circulation pumps 41 and 54 are operated from an eccentric (not shown) to cause radially reciprocating motion in the direction of the arrows 43 and urge flow of liquid through pipe 44 through apertures 36<SP>1</SP> in a plurality of evaporation tubes 47 and return flow via pipe 52 to the peripheral region 39 of the receiver drum 5. The inside of each tube 2 is provided with a system of grooves 56 to provide a high capillary effect with respect to the liquid. Joining the header drum 3 and the receiver drum 5 is a portion 4 which acts as an expansion engine of a vapour prime mover.
