Performance Evaluation and Enhancement of Bagasse Based Power Generation

Abstract

Electrical power generation by using baggasse as fuel is a profitable by-product in sugar industry. This research deal with the possibility of getting the maximum output of the power generation during the crushing season and the off-season and hence highlighting the technical problems encountered and doing the required enhancement. The method used is the data gathered from the operation log book. Based on baggasse ,steam and energy balance, it was found that Assalaya Sugar Factory crushes 290 tons of sugar cane per hour (TCH) that have 18.5% fiber and 39.0% baggasse which is used for generating 17.2 MW (10.9 MW for the 13MW turbo-alternator and 6.3MW for one of the two existing 6.5 MW turbo-alternators) with the other 6.5MWwhich has to give 6.3MW not running due to lack of hardware ( because the existing 7.5 MVA transformer connecting between the 3.3KV and 11KV bus bars is under size), adding new transformer of 7.5 MVA capacity will increase the output power to be 23.5 MW. By increasing the crushing rate to 295 TCH and running the factory for 150 days , this make the 13MW power plant unit running in the off- season for extra 85 days .
