Introduction
Analysis of the core content of the standard
| Waste heat type | Temperature range | Typical carrier | Recommended technology |
|---|---|---|---|
| High grade | ≥300℃(gas)/200℃(liquid)/700℃(solid) | Coke oven raw gas, converter flue gas | Waste heat boiler, ORC power generation |
| Medium grade | 200-300℃(gas)/95-200℃(liquid)/400-700℃(solid) | Sintering waste gas, billet radiation heat | Heat pipe heat exchanger, steam generation |
| Low grade | <200℃(gas)/<95℃(liquid)/<400℃(solid) | Slag flushing water, circulating cooling water | Absorption refrigeration, heat pump |
Key technology implementation path
Steel industry application case
A steel plant uses a dual-pressure waste heat boiler to recover 350℃ waste gas from the ring cooler for power generation, and the 150-220℃ low-temperature section is cooled by Organic Rankine cycle secondary power generation, achieving a 27% increase in energy utilization. The system integration solution includes:
- High temperature section: waste heat boiler → steam turbine power generation
- Medium temperature section: heat medium water system → process heating
- Low temperature section: hot water type lithium bromide unit → regional cooling
Energy saving benefit evaluation system
According to GB/T 13234 standard, a petrochemical enterprise aromatics unit has achieved:
- The pressure of the residual liquid tower was increased to 0.3MPa
- Kalina cycle power generation unit was put into use
- Heat medium water system integration
Achieved annual energy saving of 32,000 tons of standard coal, and the investment recovery period was 4.8 years.
Background of Standard Evolution
Compared with the 2010 version of the specification, the 2020 version has the following major updates:
- Added mixed carrier waste heat classification
- Refined the performance indicators of thermal storage equipment
- Strengthened technical requirements for ORC power generation
- Improved the cross-industry case library (Appendix CF)
