GB/T 27721-2011 "Calculation Method of Energy Balance and Energy Efficiency for Groundwood Pulp System" specifies the calculation method for energy balance and the evaluation indicators for energy efficiency in groundwood pulp systems, applicable to groundwood pulp production lines. It clearly defines the system boundary to include supporting units such as the groundwood grinder, raw material conveying, and wastewater treatment, standardizes the calculation of energy income and expenditure items including electricity, steam, and energy carried by raw materials, and establishes the formulas for calculating energy efficiency and the statistical period. This provides a basis for energy consumption management and optimization in groundwood pulp systems.
