Abstract: A center feed system for use within a delayed coking system, or any other similar system is described. The center feed system features an inlet sleeve which slidably engages a retractable nozzle, with inlet and outlet, in fluid connection with a feed source of residual byproduct, allowing residual byproduct to flow from the feed source into the interior of a vessel, thus effectuating or inducing even thermal distribution throughout the vessel.

Abstract: The invention relates to a method and a device for evacuating hot raw gases which occur in the oven chambers of a coke oven battery during coking. The oven gases are lead from the oven chambers into a hot gas collector. The pressure in the oven chambers is controlled by shut-off and throttling devices which are arranged in the hot gas streams between the raw gas outlet of the oven chambers and the hot gas collector. The positions of the devices are controlled according to the pressure that is measured in the allocated oven chamber. The gas of the hot gas collector is supplied to a steam boiler firing or a fission reactor.

Abstract: An evaporator includes a tank covered by a lightweight lid which is easily lifted to avoid high pressure in the event of an explosion. The bottom of the tank includes a flat portion which slopes downwardly toward an outlet in the sidewall of the tank. The flat section is substantially wider than the outlet to accommodate use of a square-nosed shovel to clean the tank. A fire tube in the bottom of the tank receives hot gases from a burner. A thermometer senses the temperature of the wall of the fire tube to respond to low liquid level in the tank, scale on the fire tube wall, and buildup of solids in the mixture. The open lower end of an upwardly extending standpipe is in liquid in the tank. The upper end of the standpipe is closed by a ball valve and extends above the mixture in the tank. Devices are provided for making the pressure in the standpipe different from atmospheric pressure.

Abstract: An apparatus and method for gas treating a particle bed wherein a uniform temperature gradient is achieved. A support member, such as a grate, serves to support a bed of particles on a surface thereof. The support member is moved in a predetermined direction. Gas is released from a plurality of positions at different depths in the bed.

Abstract: A body is provided with at least two cylindrical swirl chambers used to form a liquid spray cone for injecting charge gases resulting from charging coal to the coke oven, and a liquid spray cone for cleaning coke-oven gas passing through the coke oven ascension pipe. The swirl chambers are made of different diameters and each has a separate tangentially oriented inlet and a separate axially directed spray nozzle. The chambers communicate with one another through a by-pass passage to provide flow of liquid from one swirl chamber to another one.

Abstract: Apparatus for treating gases produced from the conversion of coal, e.g., from carbonization of coal, to remove the undesirable constituents thereof is disclosed. The method involves passing the hot raw gases from the coal conversation process over a coke bed at a temperature of more than 1100.degree. K. The coke bed is located in the coal gasification reactor and is provided with an ordinary air supply. The subject method achieves a significant reduction in undesirable constituents in the gas and eliminates the need for auxiliary gas treatment systems, oxygen production systems and the like.

Abstract: A spray nozzle for use in the elbow interconnecting a coke oven ascension pipe and a main, characterized in having frusto-conical nozzle orifices to generate sprays which commpletely cover the elbow cross section only when they reach the transition between the elbow and the coke oven main. The invention resides in the realization that in order to optimize the performance of the nozzle, there must be a specified relationship between the inlet diameters of the frusto-conical orifices, the outlet diameters of the orifices and the radial and circumferential distances between the centers of orifices arranged in concentric circles.

Abstract: To increase the temperature at which a tar separator operates which separates tar from condensate obtained by cooling coking gas produced by coking preheated coal, the condensate is preheated by heat exchange with the coking gas entering a raw gas cooler and is then admitted into the coking gas collecting main of the coking ovens, from which it passes to the tar separator. A method and an apparatus are disclosed.

Abstract: A method of cooling and dedusting degasification gases which escape from coal degasification chambers particularly gases which are obtained in high temperature or low temperature carbonization of bituminous and subbituminous coals and which pass from degasification chambers through risers and bends into collection mains and in the bends or in the collecting mains themselves which comprises directing crude tar having a temperature in excess of 50.degree. C. and lower than 170.degree. C. into the bends and collecting mains either alone or with water added which has a temperature and is of a quantity such that it completely evaporates in the collecting main.

Abstract: Injection of steam into the ascension pipe of each coking chamber in a coking plant is continued for a period of time after charging of that chamber so as to create a slightly sub-atmospheric pressure in the chamber during the initial stage of the coking process, in order to reduce leakage of gas and fumes to the atmosphere past the doors and filling openings. A time clock operated by the coke pusher machine or by the coal charging machine stops this injection of steam after a desired period of time.

Abstract: An exit air duct for the discharge of gases produced in coke-ovens, provided with a collection duct which on its top side has a slot extending parallel thereto. A box-like superstructure that extends parallel to the collection duct adjoins the wall thereof on either side of the slot and has an open top side and underside. The top side of the superstructure carries a guide for a flexible cover belt which serves to seal the top side and which can be lifted off locally to admit the gases. An upper grate is located in the superstructure on the top side thereof and consists of screen plates extending transversely to the superstructure. Additionally, an air duct is formed in the superstructure below the guide and the grate and extends parallel to the superstructure.

Abstract: Equipment for exhausting gases from a collecting device including an outer collection duct having longitudinal openings covered by a flexible belt. The collecting device is shifted along said duct while lifting the belt off the collection duct. Located within the outer collection duct is a longitudinally extending arcuate member defining on its side opposite to said belt an inner collection channel for directing exhaust gases out through the collection channel while preventing contact of said exhaust gases with the belt to prevent deterioration thereof.

Abstract: Control of emission from coke ovens during charging. A bank of coke ovens is provided with two gas mains. The first of the gas mains is connected to each of the individual ovens in turn during charging. The second of the gas mains is connected to the bank of ovens during coking. A fluid energized venturi ejector maintains a predetermined level of vacuum at the head of each individual coke oven during charging. Means are provided to automatically reduce the suction provided by the ejector if the level of vacuum exceeds said limit. This means consists of a valve operated by changes in the level of vacuum at the head of the individual oven during charging. The valve connects the second main to the first, thus increasing the gas pressure applied at the throat of the venturi ejector in turn decreasing the degree of vacuum provided by the venturi ejector. The energy for the ejector may be provided by flushing liquor or by a compressible fluid such as steam, air or an inert gas.
