Abstract
A coke quenching steam generator comprising a vertical, refractory-lined pressure vessel for quenching of incandescent coke and producing useful steam from the sensible heat in the coke. Included in the pressure vessel are pressure-tight doors for receiving and discharging the coke, water sprays for quenching the coke, a hopper for receiving the coke and a gate and feeder for controlling the discharge of the quenched coke. External to the pressure vessel are a crane for lifting containers of incandescent coke to the receiving hopper of the pressure vessel, valves for controlling the flow of steam and water, a high efficiency cyclone for cleaning the steam, a belt conveyor for receiving the quenched coke, pumps, water storage tank, piping and controls.
Claims13
A batch process for quenching incandescent coke and producing steam at superatmospheric pressure, comprising:
- a. feeding the coke into the top of a vertically disposed pressure vessel to substantially fill said vessel with a stationary batch of coke;
- b. sealing said vessel sufficiently to contain steam at superatmospheric pressure;
- c. spraying water radially outwardly into said batch of coke through a plurality of nozzles disposed within and surrounded by said batch of coke to directly quench said coke and produce steam;
- d. when said steam has reached a predetermined level of superatmospheric pressure, opening a steam discharge valve and delivering steam from said vessel through said valve at superatmospheric pressure;
- e. when said quenched coke has fallen to a predetermined temperature, discontinuing said spraying, closing said steam discharge valve, and opening a steam vent valve to release the pressure in said vessel;
- and
- f. after the pressure in said vessel has fallen to approximately atmospheric pressure, discharging said batch of coke through the bottom of said vessel.
A coke-quenching superatmospheric steam generator apparatus comprising:
- a. a vertically disposed pressure vessel having a receiving gate at its top for receiving incandescent coke and a discharge gate at its bottom for discharging quenched coke;
- b. means for sealing said gates sufficiently to contain steam at superatmospheric pressure;
- c. a plurality of spraying nozzle means centrally disposed within said vessel to spray water radially outwardly into coke contained in said vessel;
- d. an outlet steam pipe extending from the inside of said vessel to outside of said vessel, and steam discharge valve means on said pipe to open and deliver steam from said vessel when said steam has reached a predetermined level of superatmospheric pressure;
- and
- e. steam vent valve means for releasing pressure in said vessel after coke contained in said vessel has been quenched.
