Single Chamber System

Single Chamber System (SCS) coking reactors are coke ovens with large coke oven volume and widths between 450-850 mm. The process includes the use of preheated coal. The reactors are separate process controlled modules with rigid, pressure stable, heating walls to absorb high coking pressure. This allows much thinner heating walls to be constructed, thus improving heat transfer and combustion. The high load bearing capacity of the side walls allows a greater range of coal bends to be charged.

This technology is mostly for consideration for new plants.

Single Chamber SystemCosts & Benefits

Parent Process: Coke Making
Energy Savings Potential

SCSs offers an improvement in thermal efficiency from 38% to 70%.
CO2 Emission Reduction Potential

The larger dimension ovens decrease the specific environmental emissions because fewer pushing operations are required per tonne coke. Emissions are directly proportional to number of pushes.
