Introduction
Analysis of the core content of the standard
This standard constructs a dual circulation model of "main industrial chain + extended industrial chain", and focuses on standardizing the three major resource circulation systems:
- Water resources cascade utilization system (5 types of wastewater reuse paths)
- Solid waste resource network (8 types of solid waste utilization directions)
- Waste heat recovery system (3 types of heat energy recovery scenarios)
Comparative analysis of key technologies
| Technology category | Typical technology | Energy saving/emission reduction effect | Applicable conditions |
|---|---|---|---|
| Energy-saving transformation | Steam turbine flow modification | Reducing coal consumption by 10-20g/(kW·h) | 135-600MW units |
| Low-temperature economizer | Reducing coal consumption by 1.4-1.8g/(kW·h) | 300-1000MW units | |
| Utilization of solid waste | Activated carbon made from fly ash | Carbon powder recovery rate ≥95% | Circulating fluidized bed boiler |
| Waste heat recovery | Condenser low vacuum heating | Thermal efficiency increased by 15-25% | Cogeneration during heating period |
Implementation points and cases
Typical problem solutions
Desulfurization wastewater treatment recommends the use of a "chemical precipitation + flue evaporation" combined process:
- After implementation, a power plant in Inner Mongolia achieved zero emissions
- Annual water saving reached 120,000 tons
- Operating costs reduced by 30%
Innovative application demonstration
A power plant in Shandong uses high-aluminum fly ash to extract alumina technology:
- Al2O3 extraction rate> 85%
- By-product calcium silicate slag is used as cement raw material
- Annual benefits exceed 50 million yuan
Background of Standard Evolution
This standard marks the transformation of the practice of circular economy in the thermal power industry from single technology application to systematic integration:
- 2005-2010: Focus on the development of fly ash building material technology
- 2011-2015: Promote the comprehensive utilization of desulfurized gypsum
- 2016-2020: Form a collaborative model for the entire industrial chain
The next step will be to strengthen the integration of new technologies such as waste catalyst regeneration and CO2 capture.
