Lowering Energy Consumption of the Yankee Hood by Raising Supply Air Temperature(PPT)

摘要

1. Energy consumption drops at higher air temperatures: 1.1 Lower air velocity is needed for the same production rate 1.2 Fan power drops more than increase in gas 2. Optimization is grade specific 3. Requires analysis of both energy consumption and cost 4. The addition of heat recovery steam generation (HRSG) becomes possible at higher supply temperatures 5. At these higher supply temperatures additional energy savings of 25-30% are possible with HRSG.
