摘要:
A hybrid combustion system is provided combining advantages of a fluidized bed combustion portion and a pulverized coal combustion portion. The former portion includes a fluidized bed chamber, a coal mill without an air separator, a recycling duct connected to the coal mill, a coal supply duct, and a spray feeder. The fluidized coal combustion portion includes a pulverizing coal mill with air separator, a blowing duct for blowing ground coal, at least one pulverized coal burner and an air recycling duct for recycling combustion air. Fluidized bed combustion takes place in a lower part of the system and pulverized coal combustion takes place above the fluidized bed combustion. Each of the portions may be independently operated of the other. A main combustion chamber is common to both the fluidized bed portion and the pulverized coal portion. A related process is also described.
摘要:
A hydraulic liquid transporter for changing of different pressure and flows prevailing in three chambers that are separated from each other, having a slurry filling pump that has a suction side and a pressure side, the suction side of being connected to a mixture collecting container, the pressure side being connected to a first pressure line, a feeding space having of three feeding chambers being connected from said first pressure line, a discharging forwarding liquid pump having a suction side and a pressure side, the pressure side of the discharging forward liquid pump being connected to a second pressure line which is connected to a mixture delivering line, a discharge forwarding line connecting the suction side of the discharging forwarding liquid pump from the feeding space, a first integral flow reversing device for connection said first pressure line from said discharge forwarding line through said feeding space, a second integral flow reversal device for connecting said second pressure line from said mixture delivering line through the feeding space, both first and second integral flow reversing devices being arranged in a relative opposed relationship with their center lines substantially coinciding with each other.
摘要:
The invention relates to an apparatus for making up feed water for a power station having a steam circuit with a steam turbine /3/ and a feed water circuit with a turbine condenser /5/. The apparatus comprises aregulated multi-stage adiabatic evaporator/5/ produces distillate from raw water for making up the feed water. The heating inlet /8/ of the evaporator /15/ is connected to the stream circuit through an ejector /14/. The distillate outlet /36/ of the evaporator /15/ providing distillated water, is connected to the feed water circuit at the turbine condenser /5/ or after it through water delivering means /19, 20/.
