  • Patent number: 4289584
    Abstract: A process for quenching hot coke discharged from an oven of a battery of coke ovens into a one-spot car. The process utilizes a unique arrangement of two sets of narrow angle spray nozzles to quench the coke. In addition to quenching the coke, one set of spray nozzles initially knocks down the peak portion of the coke pile and distributes the coke so that the exposed surface of the coke is substantially level. The quench liquid discharged through the narrow angle spray nozzles contacts about 50% to about 70% of the substantially level, exposed surface of the hot coke. Sufficient openings are provided adjacent the bottom of the one-spot car to drain the quench liquid to prevent the buildup of quench liquid in the quench car.

  • Patent number: 4288294
    Abstract: The present specification describes and claims a method and apparatus for use in cooling the solid residue of gasification of a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials. The residue of gasification is conducted out of the reactor into a cooling apparatus located therebelow and flows through the cooling apparatus from the top to the bottom thereof. A cooling liquid is introduced into the solid residue in the upper region of the cooling apparatus and is metered such that the greater portion of the heat contained in the residue is eliminated in the form of heat of vaporization, sensible heat and chemical binding energy with the resultant steam and reaction products produced. The remaining residual heat which corresponds to the difference between the desired final temperature and the temperature after cooling by the liquid, is eliminated by a gas blown into the bottom region of the cooling apparatus and/or by indirect heat exchange.

  • Patent number: 4284478
    Abstract: Hot coke produced in a coke plant is introduced into the lower portion of a sealed interior of a quenching tower. Quenching water is supplied to the hot coke, thereby cooling the hot coke and generating steam and quenching gases which rise from the quenched coke to the upper portion of the interior of the quenching tower. Condensing water is supplied into the upper portion of the interior of the quenching tower, thereby condensing the steam to form quenching water condensate. A water mixture of the condensing water and the quenching water condensate is collected at a midportion of the interior of the quenching tower, and such water mixture is prevented from passing to the lower portion of the interior of the tower. The thus collected water mixture is discharged from the interior of the quenching tower, and the quenching gases remaining in the upper portion of the interior of the quenching tower are removed without being directly discharged into the exterior surrounding environment.

  • Patent number: 4280876
    Abstract: Method and apparatus for pyrolyzing agglomerative coals which comprises introducing a fluidized bed of hot char particles into a pyrolysis chamber or reactor, and injecting upwardly into the chamber a high velocity jet of agglomerative coal particles in a carrier gas, the fluidized hot char particles surrounding the high velocity coal jet and heating the coal particles to yield gaseous products and char. The hot char particles in the fluidized state and disposed around the coal jet are entrained in the upwardly expanding coal jet and mixed with the coal particles, so that by the time the coal particles contact the pyrolysis chamber wall, such coal particles being heated by the char have passed through the tacky state and are no longer tacky and do not adhere to the chamber wall. The gaseous product and char formed during pyrolysis are rapidly removed from the pyrolysis chamber, and such char can be separated, e.g.

  • Patent number: 4280878
    Abstract: The wood gases of a facility for the carbonization of wood to produce a lump charcoal are passed to an afterburner. The afterburner utilizes auxiliary burner units set at an angle to the combustion chamber centerline to provide heat for increasing the temperature of the refractory liner to the combustion level. Combustion air is introduced into the chamber resulting in a rapid mixing of the air with the gas. As a result of the introduction of the combustion air, a cyclonic movement of the flame occurs resulting in continuous contact between the gas and the hot refractory during its passage through the combustion chamber. The burned wood gases are maintained at a predetermined temperature by mixture with ambient air and supplied directly for an end use comprising lumber drying kilns. The burned wood gases are thus capable of economically drying southern pine lumber to 20% moisture content in one-fifth the time required by natural air drying.
