چکیده انگلیسی
This work estimated the energy consumption of three straw-collection systems: baling, forager and whole-plant harvest system in which the chopped cane and straw are separated at the mill. About 12 t haâ1 yrâ1 of straw can be collected for a typical sugarcane yield of 100 t haâ1 yrâ1. The system with the lowest energy consumption was whole-plant harvesting, which used 2.0 L of diesel fuel per tonne of straw collected for a harvest area 30 km from the mill and when 75% of straw is collected. This value is approximately 40% lower than of the specific consumption estimated for the other systems and just 1-2% of the energy available from the straw. However, for successful application of the whole-plant harvest system, it is needed significant improvements to the efficiency of cane cleaning systems for straw separation. The thermal energy available from the straw when 75% is recovered is 182 GJ haâ1 yrâ1, compared to 151 GJ haâ1 yrâ1 of the ethanol that can be produced and approximately 174 GJ haâ1 yrâ1 from the bagasse. If cane straw were used for electricity generation, an additional 12.6 MWh haâ1 yrâ1 could be generated.
