Performance Optimization of a Fan System Overcoming Impacts of Modified Design Criteria Due to Regulatory Requirements and Changed Operating Conditions

摘要

The Louisiana Pacific mill in Tomahawk Wisconsin manufactures oriented-strand board. Several large induced-draft fans and combustion-air blowers were operating inefficiently at this mill. this case study highlights a systems approach that was applied to address fan inefficiency. Energy savings from optimizing the system are estimated to be 338 kW, nearly half of the original measured input power of 678 kW. The project is currently being implemented and will have a payback period of less than 8 months. The opportunities here are typical of opportunities thought to exist in most industrial plants. In this case, process needs changed due to environmental regulations and change of location, but the system did not, leading to low overall system efficiency.
