Kiln capacity may also suffer. The problems are worsened if the kiln is also operated with too little oxygen, which lowers the flame heat flux intensity and reduces the available melt. Reducing kiln conditions can also affect clinker properties and accelerate sulphur recirculation, which can add to the dustiness and also accelerate kiln build-ups.
