Title: Pressurized fluidized-bed boiler
Inventor: FUJII MAMORU
IPC: F23C10/16
Filed: 1990-03-30
Abstract: PURPOSE:To obtain a pressurized fluidized-bed boiler capable or preventing decreases in temperature of a fluidized bed in casting the bed material by providing a heating means for heat insulation of the head material which is recovered and preserved in a bed-material preserver. CONSTITUTION:Upon an increase in load, a bed material preserved in a preserver 11 is transferred and cast into the fluidized bed through a bed-material casting line 14 by high-pressure air from a transfer gas line 15, and the quantity of coal and the pressure of combustion air vary with load to force the fluidized bed into rises up to levels equivalent to load. At this time, a part of high- temperature combustion waste gas is blown into the bed material in the bed- material preserver 11 through a heating line 19 from a nozzle 17 to keep the bed material in the preserver 11 fluidized and heat-insulated; therefore, casting the high-temperature bed material in the preserver 11 into the fluidized bed prevents decreases in temperature of the fluidized bed on casting. Thus, the absorption heat of combustion heat in the fluidized bed to a heat transfer surface does not decrease momentarily, so that the output of a turbine 9 by steam does not decrease with the result that follow-up property in rises in load improves.

Title: Fuel injection pump in diesel-engine
Inventor: UEDA YOSHIKIYO
IPC: F02B3/06
Filed: 1985-04-24
Abstract: PURPOSE:To increase the pressure of inside of a pump even during low load operation to aim at enhancing the combustibility of a Diesel-engine, by providing an accumulator communicated with a plunger chamber, and a discharge control valve disposed in an oil passage between the plunger chamber and a discharge valve. CONSTITUTION:A plunger 9 starts its ascent as a cam 5 rotates. A discharge valve push-rod 15 and an overflow valve push-rod 10 start to ascend simultaneously. At this time fuel in a plunger chamber 13 is compressed while the plunger 9 ascends, and the thus increased pressure of fuel is accumulated in an accumulator 3. When the plunger 9 further ascends, a discharge control valve 14 is opened to allow the accumulated high pressure oil to flow into a discharge valve 7. When the pressure becomes higher than the pressure of inside of a high pressure pipe line 2, the discharge valve 7 is pushed upward to allow fuel to be fed to a fuel valve 1 and to be injected. When the plunger ascends further more, an overflow valve 8 is opened, and therefore, high pressure oil in the plunger chamber 13 flows out as indicated by the arrow 21. Therefore, the discharge valve 7 is closed to terminate the fuel injection.
