Evaluation of the energy efficiency of the shell coal

2017-7-1 · The energy demand of the gasification system and related units (air separating unit, coal treatment, and steam consumption) was in the range of 39.4–40.2 MW, which showed a small difference among coal types. Consequently, the energy efficiency of the gasifier strongly depended on the HHV of coal.
