1 Scope
This standard specifies the calculation method of dry and wet straw stock preparation system energy balance and energy efficiency.
This standard applies to the energy balance of dry and wet straw pulp and paper companies and the energy efficiency stock preparation system of testing and calculations.
2 a block diagram of the energy balance
2.1
dry and wet straw stock preparation system block diagram shown in Figure 1 energy balance.
1 dry and wet straw stock preparation system block diagram of FIG energy balance
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.
