JC/T 545-2020 in English

JC/T 545-2020 standard has established a complete energy management system for glass fiber factories. The main technical breakthroughs are reflected in:

• The four-link energy balance model (purchase storage/processing conversion/transmission distribution/terminal use) is introduced for the first time
• The new statistical-testing dual-track system calculation method is added, and the energy metering equipment is required to comply with GB 17167
• The requirements of the 1994 version of the energy flow diagram are cancelled, and the data empirical analysis

Typical application scenarios

Take an enterprise with an annual output of 100,000 tons of glass fiber yarn as an example:

1. The melting process accounts for 58% of the energy consumption, and the kiln temperature curve needs to be monitored.
2. The electricity equivalent value conversion coefficient is 0.1229kgce/(kW·h)
3. The loss rate of the transmission pipeline network is controlled at ≤1.2%

• Establish an energy management center system to achieve real-time monitoring
• Promote waste heat recovery technology for raw silk drying
• Regularly conduct leakage plate thermal balance test (refer to GB/T 25039)
