Harvesting, storing and application of elephant grass (Miscanthus sinensis (``Giganteus``)) for combustion purposes; Hoest, opbevaring og anvendelse af elefantgraes (Miscanthus sinensis (``Giganteus``)) til fyringsformaal

Abstract

The technical requirements for harvesting Miscanthus sinensis (elephant grass) are discussed. At 38 kW the hourly capacity of forage choppers with conventional grass headers is 4 tons, with maize headers capacity will be 10 tons at 37 kW. Stems may accumulate in the feeding mechanism and reduce capacity. Advantages are a single working process, non-pickup of leaf fragments and the possibility for combustion of chopped matter in the automatic stoker. But harvest capacity is relatively small, moisture content in the chopped matter can be too high and it can be difficult to handle and transport. A big baler fitted with a chopper should be equipped with a special counter knife and counterknife. Capacity of of a big baler fitted with a chopper is 9 tons per hour at 54 kW. Harvesting can be performed without interruptions, waste produced during mowing is avoided, but leaves from the ground will be picked up. Field drying, and frequently baled-crop drying is not possible. Mowing can be performed with a mower equipped with a crimper, a capacity of 35 tons requires 27 kW. The capacity of big balers is 25 tons at 24 kW or more. A high pressing capacity is possible, handling, transport  More>>

The capacity of big balers is 25 tons at 24 kW or more. A high pressing capacity is possible, handling, transport and storage is rational. A low moisture content can be achieved by leaving the crop in swathes. Some waste and leaf pickup cannot be avoided. Big bales can be stored at a moisture content of 25%, when not loose in a silo. Combustion properties are good, thermal value is 15 Mj/kg and the ash content 2.5. In a batch stoker combustion is more efficient than is the case with straw. (AB).}
