2.2 System boundary. the straw from the feed belt into the system, after grass cutting machine, hydraulic mulching machines and other equipment sent from the rotary feed screw, into the digester workshop.

3 energy balance calculation formula described

3.1 Calculation of heat Do not use wet and dry steam throughout the straw stock preparation system, there is no steam consumption. The water reuse water are required, and the temperature change Of small, so the heat can be calculated negligible. 3.2 Energy calculation (to calculate the total power load system-wide P) Calculate the total power load system-wide P see equation (1), namely. ......
