YB/T 4962-2021 The energy limit and energy efficiency level of blast furnace circulating cooling water systems
Basic Information
Scope
This document specifies the terms and definitions of energy consumption limits and energy efficiency grades for blast furnace circulating cooling water systems in steel enterprises, energy efficiency indicators and energy efficiency grade classification, and methods for improving the energy efficiency grade of blast furnace circulating cooling water systems. This document is applicable to the measurement and calculation of energy consumption for blast furnace circulating cooling water systems, the calculation of energy efficiency ratios, and the assessment of energy efficiency grades. It can also be used as a basis for determining whether existing blast furnace circulating cooling water systems need to be modified and for selecting modification schemes.
