Title: Improvements in steam generator furnaces
IPC: F22B9/12
Filed: 1920-10-27
Abstract: 172,832. Crosby, J. E. Oct. 27, 1920. Smoke, consuming.-In return-tube steam boilers having two or more furnaces, dampers are provided in the smoke-boxes whereby the smoke from one or more of the furnaces, after passing through the tubes of the boiler, can be delivered to one or more of the other furnaces to be consumed. In the arrangement shown, each smokebox has an opening below, communicating with an extension of the fire-door frame of the corresponding furnace and fitted with a damper as shown at n, o, p. The partitions between the smoke-boxes have openings j in their lower parts. Sliding dampers t, u, v are fitted between the smoke-boxes and the uptake. The dampers are operated by means of shafts k with arms connected to the bottom dampers and wheels 7 carrying chains connected to the top dampers, as shown in Fig. 2, so that, when any bottom damper is lifted, the corresponding top damper is opened, and when the bottom damper is lowered the top damper is closed. The dampers being suitably adjusted, the smoke from a smoke-box having its top damper closed may thus pass through the opening j into the space below the raised bottom damper in the adjoining smokebox and thus to the fire of the adjacent furnace.

Filed: 1967-02-28
Abstract: 1,207,982. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 2 Feb., 1968 [28 Feb., 1967; 9 May, 1967; 30 June, 1967], Nos. 9482/67, 21603/67 and 30375/67. Heading G6C. In a carbon dioxide cooled, graphite moderated nuclear reactor, gas flows downwardly through the graphite, is reversed at the base and flows upwardly through the fuel element channels. The coolant gas contains a corrosion inhibitor and gas diffusion into the graphite is also induced. Downward flow takes place in the passages 28, 29 to the chamber 32. From 32, through passageway 33 the gas flows upwardly through the fuel channel 27. The flow restrictors 20 and 26 produce pressure drop which causes gas diffusion through the graphite, radially outwards. To prevent leakage of gas between the separate moderator bricks 1, 1<SP>1</SP> sealing rings 6 are accommodated in circular grooves in the brick faces. The bricks may rock relatively to each other by means of tapered gaps between the faces.
