Abstract
Abstract An improved method for byproduct coke oven operation wherein the problems of pollution caused by charging, oxidation of green coke, pushing and quenching are eliminated by the quenching operation taking place within the oven prior to the removal of the doors and pushing of the coke; the combustion gases created by the charging, and the steam and water gases generated by the quenching are extracted and completely burned in an afterburner prior to the gases being dust-cleaned in a precipitator. The coke being quenched in the sealed oven to a temperature lower than the ignition point of the coke eliminates the oxidation thereof after it is pushed from the oven thereby increasing the efficiency of the oven from the standpoint of yield.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
12 words
directing a quenching medium into said cleavage volume through said opening; and,
Claim 2
Dependent Claim
28 words
The method as set forth in claim 1 further including recovery heat from said afterburner in order to make use of waste heat from the steam gas generation.
Claim 3
Dependent Claim
80 words
The method as set forth in claim 1 further including introducing a spraying system into said oven and wherein forming said opening comprises introducing high-pressure air through said spraying system to impinge on the surface of the coke and thereby pierce and bore at least a hole in the coke through which a water spray is directed to the center of the coke to thereby quench the coke from the center of the coke body outwardly towards the oven walls.
Claim 4
Dependent Claim
54 words
quenching said coke body by cooling the body commencing from the inside of the body to the exterior surfaces and thereby avoiding impinging quenching medium on walls of the oven; e. collecting and processing steam and gases produced in said oven during quenching; and, f. removing the quenched body of coke from the oven.
Claim 5
Dependent Claim
80 words
The method as set forth in claim 1 further including introducing a spraying system into said oven and wherein forming said opening comprises introducing high-pressure oxygen through said spraying system to impinge on the surface of the coke and thereby pierce and bore at least a hole in the coke through which a water spray is directed to the center of the coke to thereby quench the coke from the center of the coke body outwardly towards the oven walls.
Claim 6
Dependent Claim
25 words
The method as set forth in claim 1 wherein the quenched coke is confined in a sealed distribution bin after the coke leaves the oven.
Claim 7
Dependent Claim
33 words
The method as set forth in claim 1 wherein the coking byproduct gases are collected in a first processing system and all other gases and steam are collected in a second processing system.
Claim 8
Independent Claim
58 words
A method of making coke in a byproduct type coke oven comprising: a. charging a byproduct coke oven with material to be coked; b. heating the material in the oven to produce a body of coke having a central cleavage volume; c. removing byproduct gases during heating; d. quenching said coke while in said oven, said quenching comprising:
Claim 9
Dependent Claim
34 words
A method as claimed in claim 7 wherein forming said at least one opening comprises directing a stream of oxidizing medium onto a limited area of said coke body to thereby pierce said body.
Claim 10
Dependent Claim
21 words
A method as claimed in claim 8 wherein directing the stream of oxidizing medium compriseS directing air onto the coke body.
Claim 11
Dependent Claim
13 words
A method as claimed in claim 8 wherein said oxidizing medium is oxygen.
Claim 12
Dependent Claim
40 words
A method as claimed in claim 7 wherein quenching said coke body further comprises inserting a flow directing member into said oven and introducing said oxidizing medium into said oven through said flow directing member to pierce said coke body.
Claim 13
Dependent Claim
35 words
A method as claimed in claim 7 wherein quenching said coke body comprises inserting a flow directing member into said oven and introducing said quenching medium into said coke body through said flow directing member.
Claim 14
Dependent Claim
22 words
A method as claimed in claim 11 further including directing said quenching medium into said coke body through said flow directing member.
