im. cl. clob 31/04' U.s. cl; 201-40 1 claim ABSTRACT OF THE DISCLOSURE The present invention relates to a method of loading charge materials into a horizontal coke oven which is provided with two risers disposed respectively at the coke pusher side and the opposite coke discharge side of the oven.
Known in the prior art is a method of smokeless charging of charge materials, in which the charge is loaded into a coking chamber rst through end doors and then through the middle ones. During the charging operation, gases are sucked into gas collectors through risers provided both at the coke pusher side and the coke discharge side of the coke oven simultaneously.
In this case, coal tar condensed in the gas collectors is found to be contaminated with coal particles to be handled by a stream of sucked gases from the coking chamber. To let this coal tar settle and to clarify it, a great number of settling tanks are required provided with a mechanized separator of oil deposits. Moreover, valve boxes, pipe bends and covers of the risers are likely to be clogged by deposits of tar and charge.
An object of the invention is to eliminate the abovementioned disadvantages by the provision of such a j method of smokeless loading of a charge into a horizontal coke oven, that is capable of supplying gases sucked from the coking chamber into a gas collector, said gases featuring a minimum content of coal particles.
The present invention is concerned with a method of loading a charge into a horizontal coke oven with sucking of gas from the coking chamber into a gas collector through risers located both at the coke pusher side and the coke discharge side of the oven, the coking chamber being charged alternately through the extreme and middle doors thereof.
AIn conformity with the invention, the method is characterized by the fact that when charging the coking chamber only through the doors located on the coke discharge side of the oven, all the other doors are kept closed, gases from the coking chamber are sucked through a riser located on the coke pusher side of the coke oven. When loading the coking chamber only through the doors located on the coke pusher side of the oven, all the other doors are kept closed, gases from the coking chamber are sucked only through a riser located on the coke discharge side of the oven, whereafter the coking chamber is loaded through doors located in the central portion of the oven, all the other doors being kept closed during this time, and gas is then sucked simultaneously through both rlsers.
The advantage of the proposed method consists in the fact that the place where the gas is sucked from the coking chamber is at a maximum remote location from the place where the charge materials are loaded into the chamber. Owing to this fact, a smaller amount of coal particles is entrained by the gas stream, while the coal particles entrained have time to drop from the gas stream in its flow path to the risers.
The details of the present invention will become more fully apparent from a consideration of the following description of an exemplary embodiment thereof, taken in conjunction with the attached drawing wherein:
FIG. 1 is a sectional side view diagrammatically showing the loading of the charge into the coking chamber and the suction of the gas therefrom; and
`FIG. 2 is an explanatory schedule of the llling procedure in theoven of FIG. 1.
Referring to FIG. l of the drawing, there are located on the coke pusher side and coke discharge side of a chamber 1, risers 2 and 3, connected to respective gas collectors 4 and 5 and facing the chamber 1.
To establish suction at the base of the risers 2 and 3, each is provided with a respective injection device 6 and 7 for supplying steam or gas. In the risers 2 and 3 are also valves 8 for disconnecting the gas collectors 4 and 5 from the coking chamber 1. Disposed in the upper portion of chamber 1 are a plurality of charging doors 9, 10, 11, above which there are provided respective hoppers 12, 13 and 14 of a coke-loading car. The junction of the hoppers 12, 13 and 14 with doors 9, 10 and 11 is sealed for the period of time when the charging operation proceeds.
The method of loading charge materials into the coking chamber 1 of the coke oven is effected as follows.
When discharging the charge from the hopper 14 through the door 11 located on the coke discharge side of the oven into the coking chamber 1, the doors 9 and `10 are preliminarily closed, the valves 8 in the risers 2 and 3 are opened, and injection device 6 on the riser 2 at the coke pusher side of the oven is actuated. The main portion of gases, evolving in the chamber 1 from the loading of the charge, is sucked through the riser 2 into the gas collector 4.
Since the valve 8 in the riser 3 is open, an insignificant portion of gases will be supplied at a small rate into the gas collector 5. Owing to the fact that the rate of gas in the riser 3 is small, particles of coal will be entrained by the gas stream from the charge.
After emptying the hopper 14, the door 11 is closed, the injection device 6 of the riser 2 is deactuated, and injection device 7 is simultaneously actuated on the riser 3. The door 9 is opened, and the charge from the hopper 12 is supplied into the coking chamber, the gas being thereby sucked through the riser 3 located on the coke discharge side of the oven into the gas collector 5. Part `'of gases will be supplied into gas collector 4, in the manner described hereinabove in the case where the charge materials were charged through the door 11. Then, when the entire charge is discharged from the hopper 12, the door 9 is closed.
The injection device 6 is then actuated and the door 10 is opened, and the charge materials are discharged from the hopper 13 into the coking chamber 1. When the charge materials are discharged from the hopper 13, the charge materials are levelled inside the chamber 1 and gas is sucked through both risers 2 and 3.
Upon completing the operation of charging and levelling the charge inside the coking chamber 1, the door 10 is closed, and.the injection devices 6 and 7 are deactuated.
Gases, evolving during the charge coking process in the coking chamber 1, are exhausted through the risers 2 and 3 into the corresponding gas collectors 4 and 5.
The filling procedure is shown in the schedule in FIG. 2.
The application of the present invention allows coal tar with a permissible ash content to be obtained.
What is claimed is:
1. A method of loading charge materials into a coking chamber of a horizontal coke oven having gas collectors at opposite sides thereof connected to the chambers through risers, and charging doors at the opposite sides of the chamber and in the center thereof, said method comprising charging the chamber with charge materials through the doors at one side of the chamber while the other doors are kept closed, producing a suction only in the riser at the opposite end of the chamber to cause gases in the chamber to travel the length thereof for discharge in the gas collector associated with the riser under suction, then charging the chamber with charge materials through the doors at the other side of the cham- Yber while all other doorsV are closed, producing a suction both risers.
