Utilization of a coke oven featuring improved heating properties

Abstract

A coke oven of a horizontal construction of the non-recovery or heat recovery type is shown. The oven has at least one coking chamber, in which laterally vertical downcomers as well as horizontal bottom flues extend underneath the coking chamber for indirect reheating of the coking chamber. At least a part of the interior walls of the coking chamber is configured as a secondary heating source by coating it with a high-emission coating (HEB) that shows an emission degree equal to or higher than 0.9, and consists of the substances Cr 2 O 3 or Fe 2 O 3 or a mixture containing these substances, with the portion of Fe 2 O 3 amounting to at least 25% by weight in the mixture, and with the portion of Cr 2 O 3 amounting to at least 20% by weight in the mixture.

1 . Utilization of one or more coke ovens of horizontal construction of the type non-recovery or heat-recovery, consisting of at least one coking chamber, laterally arranged vertical downcomers as well as bottom flues arranged horizontally and underneath the coking chamber for indirect reheating of said coking chamber, wherein at least a part of the interior walls of the coking chamber is configured as secondary heating surfaces by coating them with a high-emission coating, with the emission degree of this high-emission coating being equal to or higher than 0.9. 
     
     
         2 . Utilization according to  claim 1 , wherein coal carbonization is carried out at a mean oven room temperature of 1,000 to 1,400° C. 
     
     
         3 . A method of using one or more coke ovens of horizontal construction of the type non-recovery or heat-recovery, each coke oven consisting of at least one coking chamber, laterally arranged vertical downcomers as well as bottom flues arranged horizontally and underneath the coking chamber for indirect reheating of said coking chamber, wherein at least a part of the interior walls of the coking chamber is configured as secondary heating surfaces by coating them with a high-emission coating, with the emission degree of this high-emission coating being equal to or higher than 0.9, comprising
 providing a coke charge to the oven; and   carbonizing the charge.   
     
     
         4 . Method according to  claim 3 , wherein the coal carbonization is carried out at a mean oven room temperature of 1,000 to 1,400° C. 
     
     
         5 . A method of making coal comprising utilizing one or more coke ovens of horizontal construction of the type non-recovery or heat-recovery, consisting of at least one coking chamber, laterally arranged vertical downcomers as well as bottom flues arranged horizontally and underneath the coking chamber for indirect reheating of said coking chamber, wherein at least a part of the interior walls of the coking chamber is configured as secondary heating surfaces by coating them with a high-emission coating , with the emission degree of this high-emission coating being equal to or higher than 0.9. 
     
     
         6 . Method according to  claim 5 , wherein the coal carbonization is carried out at a mean oven room temperature of 1,000 to 1,400° C.
