Method for a cyclical operation of coke oven banks comprised of" heat recovery" coke oven chambers

Abstract

A method for cyclical operation of a coke oven facility which includes an even number of coke oven banks which in turn include an even number of coke oven chambers is shown. Located downstream of the coke oven banks are boiler facilities which drive turbines with the hot waste gases from the coke oven banks. Energy is recovered in this manner. The coke oven chambers are pushed and charged in an exactly determined cycle so that the production of hot waste gas over the temporal mean can be homogenized.

         16 . A method for cyclical operation of a sequence coke oven banks of the “Heat Recovery” type in an even or odd number comprised of at least four coke oven banks, comprising an even or odd number of coke oven chambers, wherein:
 the coke oven banks proper comprise a sequence of at least four coke oven chambers of the “Heat Recovery” type; 
 the coke oven banks are linked to a boiler system in which the heat of hot waste gases from the coke oven banks is utilized to generate steam; and 
 the coke oven chambers are pushed and charged within exactly determined time intervals from the frontal side with a coke pusher machine into the opposite direction of a coke oven chamber, and that directly after pushing a renewed charging of the individual coke oven chambers and a renewed coking cycle are accomplished, the process comprising: 
 in a first pushing cycle the first coke oven chamber of the first coke oven bank is initially pushed and charged, and wherein the first coke oven chamber each of the next but one coke oven bank is consecutively pushed and charged until the first coke oven chamber of the last but one coke oven bank has been pushed and charged, if the number of coke oven chambers per coke oven bank is an even number; and 
 in a succeeding second pushing cycle the next coke oven chamber of the next coke oven bank within this sequence is initially pushed and charged, and wherein then in successive order the coke oven chamber being the same in this sequence of the next but one coke oven bank is pushed and charged until the coke oven chamber being the same in this sequence of the last coke oven bank has been pushed and charged; and 
 in a succeeding third pushing cycle the next but one coke oven chamber in this sequence of the first coke oven bank is pushed and charged, and wherein then in successive order the coke oven chamber being the same in this sequence of the next but one coke oven bank is pushed and charged until the coke oven chamber being the same in this sequence of the last coke oven bank has been pushed and charged; and 
 in a final pushing cycle the coke oven chamber being the last one in this sequence of the first coke oven bank is pushed and charged, and wherein then in successive order the last coke oven chamber each of the next but one coke oven bank is pushed and charged until the coke oven chamber being the last one in this sequence of the last but one coke oven bank has been pushed and charged so that:
 over the temporal mean of all coking cycles a very even production of waste heat can be passed in this manner into the boiler facilities so that the boilers can be supplied very evenly with waste heat.

 over the temporal mean of all coking cycles a very even production of waste heat can be passed in this manner into the boiler facilities so that the boilers can be supplied very evenly with waste heat.
