摘要： A boiler having a hot gas generator for burning liquid or gaseous fuels. The hot gas generator comprises a combustion chamber unit, into the combustion chamber of which the fuel and air for combustion are introduced and in which the combustion of the fuel takes place. The combustion gases are conveyed out of the combustion chamber into a water cooled boiler firebox. A compressor supplies the air for combustion into the combustion chamber unit. A flue gas conduit, which leads to the flue gas vent of the boiler, at its inlet end, which is connected with the boiler firebox, is connected with the air intake of the compressor of the hot gas generator for recirculating a regulatable amount of flue gases into the combustion chamber unit of the hot gas generator. The flue gas conduit offers a resistance to the flow of flue gas therein, which resistance is greater than the chimney draft force present in the flue gas vent of the boiler.

摘要： A boiler has a rectangular combustion chamber with an oil burner (1) firing horizontally in the front wall. Between the burner and the target wall there is an insert (3). The insert has a cylindrical section (4) nearest the burner and a conical section (5) furthest from the burner. The base of the cone is towards the burner and the truncated apex is attached to a plate (10) which is screwed to a support bracket (6). The support bracket has a base (7) which fits to the bottom of the combustion chamber. The insert is made of stainless steel wire and sheet and is brought to white heat by the flame. It stabilises the flame and reduces the formation of soot.

摘要： The devices increases the efficiency of combustion by bringing the combustion gases in contact with a hot surface. The pre-heater consists of a cylinder (1) made of suitable material or refractory material. The cylinder is fitted with helical fins (2). The cylinder is hollow, and one end is closed except for a discharge orifice (3) and rests on a base (5). The pre-heater is placed in the furnace. The cylinder becomes hot, and increases the combustion efficiency of the gases coming into contact with the inside of the cylinder.

摘要： 1341271 Coke ovens SIMON-CARVES Ltd 19 April 1971 [3 Nov 1970] 23705/71 Heading F4B In a rich gas fired twin flued regenerative coke oven, pipes 33 and 34 respectively feed low and high level burners in one group of heating flues, and pipes 35 and 36 respectively feed low and high level burners in the alternate group of heating flues. In operation, gas is fed through open cocks 28 via pipes 33 and 34 to the burners of the first flue group, whilst cocks 29 in the pipes 35. and 36 are closed to shut off gas flow to the alternate flue group. Pressurized decarbonizing air can be admitted to the pipes 35 and 36 at this time from line 37 through fourway cock 39. In a first position A of the cock 39 air is admitted only to pipe 36 to decarbonize it and its associated burners,in a second position B air is admitted only to pipe 35 for a like purpose, and in a third position C a throttled supply of venting air is admitted to both pipes to prevent flue gases from the " off" heating flues flowing back down them. Alternatively, in this third position the pipes 35 and 36 could be vented to atmosphere via a slot in the housing of the cock 39. A similar four way cock 38 prevents decarbonizing air passing to pipes 33 and 34 whilst gas is passing through them. On reversal, i.e. positions D, E and F, gas is fed through the pipes 35 and 36 and decarbonizing air via cock 38 to the pipes 33 and 34. The period during which decarbonizing air is fed to any given pipe is restricted to the minimum necessary to completely decarbonize that pipe and the associated burners. This may be longer for the high level burners than the low level burners.
