摘要： PURPOSE:To enable high-efficient recovery of heat possessed by a solid material without complication of equipment and operation by a method wherein heat is taken out to external part from the thickened part of the solid material formed in the middle of an external circulating route. CONSTITUTION:Combustion gas produced by combustion is raised within a fluidized bed combustion chamber 2 together with dust. Combustion gas away from which dust is separated by means of a cyclone 5 is fed through a discharge pipe 6 to a convection boiler 7. A heat transfer pipe 8 is arranged in the convection boiler 7, and heat possessed by combustion gas flowing through the discharge pipe 6 is recovered by fluid flowing through a heat transfer pipe 8. Meanwhile, a solid material, e.g. an unburnt component, an ash component, separated away from the combustion gas by means of the cyclone 5 is lowered to a return pipe 11. The solid material gathers at a bent part being the lower part of the return pipe to form a particle thickened part 12. A heat transter pipe 14 is arranged to the particle thickened part 12, and since fluid 15, e.g. water, flows, heat possessed by the solid material is transferred to the fluid 15 through the pipe wall of the heat transfer pipe 14 with high efficiency. This constitution simplifies recovery of the heat of the solid material, e.g. an unburnt component, an ash component.

摘要： PURPOSE:To produce quantities of heat through improvement of a ratio of a charcoal material consumed for combustion by a method wherein when combustion gas is discharged to the outside of a system, fly ash, having a specified grain size or more, of fly ash separated away from combustion gas by means of a dust collector is graded and blown in a fluidized bed combustion chamber. CONSTITUTION:Combustion gas is fed to a convection boiler 9 and the heat of which is recovered. After dust is removed from the combustion gas by means of first and second dust collectors 10 and 11, the combustion gas is discharged to the outside of a system by means of a blower 12. In this case, a solid material with a grain size of 2mum or more is separated away from a solid material by means of the first dust collector 10 and fine dust is separated by the second dust collector 11. Fly ash with a grain size of 2mum separated by means of the first dust collector 10 is returned through a coarse grain return pipe 15 to a fluidized bed combustion chamber 2. The coarse grain return pipe 15 is opened in a level higher than that of a secondary air introduction pipe 5 and in the fluidized bed combustion chamber 2. Since this position is a part where the internal pressure of the fluidized bed combustion chamber 2 is comparatively low and oxygen concentration in the fluidized bed combustion chamber 2 is increased by means air blown through the secondary air introduction pipe 5, excellent combustion at an unburnt part located to the central part of fly ash is effected.

摘要： PROBLEM TO BE SOLVED: To provide a control method for a constant temperature condenser preventing rising of a condensation temperature of a high pressure condenser, and capable of preventing supercooling.
SOLUTION: In the control method, the condensation temperature, an outlet pressure, and an inlet steam amount of the high pressure steam condenser 2 are respectively detected, and feedforward control is carried out to carry out constant control of the condensation temperature and constant control of the outlet pressure of the high pressure steam condenser 2 by a high pressure steam condenser fan 5. When the outlet pressure increases and reaches a maximum pressure set value, the high pressure steam condenser fan 5 for cooling is automatically started, and when the inlet steam amount and the condensation temperature are lowered to respective minimum set values, the high pressure steam condenser fan 5 is stopped.

摘要： PURPOSE:To cause combustion to be stable and enable combustion heat to be efficiently recovered from combustion gas by a method wherein a liquid fuel supplying angle is specified at a lower level than that of a feeding port of secondary lower stage air into a fluidized bed combustion chamber. CONSTITUTION:Liquid fuel is supplied into a liquid fuel supplying pipe 35 mounted at a lower level of a secondary lower stage air feeding pipe 24 from a fuel injection gun 36 at the same central axis. At this time, a level ratio between the supplying pipe 35 and the secondary lower stage air feeding pipe 24 is from 0.3 to 0.8. Liquid fuel is supplied from the liquid fuel injection gun 36 having an angle formed between an axis of the liquid fuel injection gun 36 and a horizontal line within a vertical line including the axis of 5 to 20 deg. and then the liquid fuel is ignited. As a result, a maximum temperature within the combustion chamber is 850 deg.C, a concentration of monoxide carbon is 180ppm and a concentration of SO2 is 90ppm, resulting in that a superior combustion state can be attained.
