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 recovered heat will be utilised for the flat plate washing water supply and the evaporation decomposition process to heat semen, ensuring the comprehensive secondary use of waste heat. 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.
