Carbonization of Coal in Heat Recovery Coke
The Sun Coke battery – Present Sun Coke battery design is based on inhouse experience since 1960. In 1989, the basic design was renewed and the JewellThompson name was adopted for the oven type. Then, in 1998, new changes were made to the design. During this time, a power plant to recover heat in the off gas is included. Present oven configuration is shown in Fig 2.

Coke Oven an overview | ScienceDirect Topics
· Coke oven emissions are the volatile products that are released from bituminous coal during its conversion to coke in high temperature ovens in the absence of air. These emissions arise from the noncarbonaceous materials present in the coal prior to processing and are complex mixtures of dusts, vapors, and gases that typically include polycyclic aromatic hydrocarbons, aliphatic aldehydes

Steelmaking: The Coke Oven ByProduct Plant
The exhauster is of prime importance to the operation of the coke oven battery. It allows the close control of the gas pressure in the collecting main, which in turn affects the degree of emissions, for example door emissions, from the battery. A failure of the exhauster will immediately result in venting to atmosphere, through the battery flares, of all of the raw coke oven gas produced. Top
