The groundbreaking ceremony for Shanxi Huaxing Aluminum's waste heat utilisation project was successfully carried out. The waste heat utilisation project marks a significant step forward in advancing energy efficiency, emission reduction, and environmentally friendly production practices.
The project aims to recover waste heat from the flue gas of the roaster by facilitating heat exchange between the roaster's flue gas and the high-temperature section of the fluidised bed cooler using a circulating heat medium water system. The plan is to lower the roaster's flue gas temperature from 160°C to 110°C and reduce the discharge temperature of the fluidised bed cooler to below 80°C.
The project will incorporate an advanced automated control system to guarantee the system's efficiency and stable performance.
This system will enable real-time monitoring of flue gas temperature, flow, and pressure, as well as the temperature and flow of the heat exchange medium. It will automatically adjust the operating parameters of the waste heat recovery equipment based on production conditions, achieving intelligent operation standards and significantly enhancing the system's stability and reliability.
Upon completion, the project will replace the steam heating system of the flat disc filter, reducing steam consumption and increasing semen temperature. This change will not only lower the company's energy costs but also significantly cut down on energy waste and environmental thermal pollution.
The project is expected to deliver substantial energy savings and consumption reductions, supporting the company's continued progress toward green and sustainable development. It will also contribute to creating a green, low-carbon "New Chinalco."
