Abstract: 115,423. Alliata, G. May 3, 1917, [Convention date]. Gaseous-fuel furnaces; air supply, regulating: indicators -Valves controlling respectively the admission of primary and secondary air in a producer gas furnace, or of the gas and combustion air in other gas furnaces, are adjusted so as to maintain two indicators or a single indicator in position corresponding with the requisite pressures. The indicator or indicators comprise a pointer or pointers controlled by pressure differences between, or the pressures in, two chambers or other parts of a furnace, through which flow respectively the primary and secondary air, or gas and air. Variations in pressure caused, for instance, by slagging in the producer furnace are indicated by deflection of the pointers, and by suitably adjusting the supply valves, normal conditions can be re-established. In one form of apparatus shown diagrammatically in Fig. 1, primary air for the combustion of coke in a produce furnace 1 is supplied under control of a valve 4 through a chamber 4<1>, while secondary air is supplied through a similar chamber 5<1> under control of a valve 5. From the chambers 4<1>, 5<1>, pipes 6, 7 lead to bell floats 9, 9<1>, which operate, through suitable levers, pointers 12, 13 moving over scales 15. The apparatus is so adjusted that, when combustion conditions are normal, the pointers will stand at the same graduation on the two scales. When variations occur, the pointers will be deflected in opposite directions, and the valves 4, 5 can then be operated until the pointers indicate that balanced conditions are re-established. In a modification, the two ball floats are connected by a lever pivoted about a knife edge; a single pointer may then be used.
