Abstract
Abstract Method for charging a coke oven chamber. Where the chamber is charged through a single charging hole with a stream of flowable preheated particulate coal at a flow rate of between substantially 8-20 tons per minute. The coal flows sufficiently in the chamber to assure filling of the chamber to substantially 100% of the volumetric capacity of the same. Due to the flowability of the preheated coal the charge is self-leveling.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
129 words
A method of charging a coke oven chamber, comprising the steps of advancing preheated particulate coal by a conveyor to a coke oven chamber; charging the chamber by admitting through a single charging hole in the top of the chamber a stream of the preheated particulate coal at a charging rate of substantially 8-20 t/min; intercepting only a minor fraction of the stream of coal below the charging hole; and imparting to the intercepted fraction of the stream of coal a component of movement diverting the intercepted fraction toward the respective ends of the chamber whereby, due to the flowability of the preheated coal particles and the diversion of the intercepted fraction, the chamber becomes charged to a uniform permissible filling level at substantially 100% of its volumetric capacity.
Claim 2
Independent Claim
129 words
A method of charging a coke oven chamber, comprising the steps of advancing preheated particulate coal by a conveyor to a coke oven chamber; charging the chamber by admitting through a single charging hole in the top of the chamber a stream of the preheated particulate coal at a charging rate of substantially 8-20 t/min; intercepting only a minor fraction of the stream of coal below the charging hole; and imparting to the intercepted fraction of the stream of coal a component of movement diverting the intercepted fraction toward the respective ends of the chamber whereby, due to the flowability of the preheated coal particles and the diversion of the intercepted fraction, the chamber becomes charged to a uniform permissible filling level at substantially 100% of its volumetric capacity.
Claim 3
Dependent Claim
56 words
A method as defined in claim 1, the width of the chamber increasing in direction from one to another end of the chamber and the charging hole being located in the region of said other end; and wherein said step of charging comprises filling said chamber in direction from said other towards said one end thereof.
