PRODUCTION TECHNOLOGY30 PRODUCTION TECHNOLOGY AAC WORLDWIDE %u2022 3.2025Keda Suremaker, Maanshan City, Anhui Province, ChinaSmart Steam Solution for Green and Efficient AAC ProductionAgainst the backdrop of global energy transition and China%u2019s dual-carbon strategy, the building materials industry is under growing pressure to improve energy efficiency and reduce emissions. Autoclaved aerated concrete, a lightweight and sustainable material, offers strong environmental performance dur,ing use. However, its manufacturing process %u2013 particularly the autoclaving stage %u2013 remains highly energyintensive. In a typical AAC plant, steam accounts for the largest portion of total energy consumption, making it the top priority for efficiency upgrades.Traditional steam systems in AAC production often suffer from frequent manual interventions, poor control accuracy, low recovery of waste steam, inefficient condensate drainage, and excessive emissions. These issues contribute to energy waste, unstable product quality, and reduced operational efficiency.To address these challenges, Keda has introduced the EcoSteam AAC Energy-Saving Solution. The system is built upon three core functional pillars that work synergistically to deliver exceptional performance:%u2022 Intelligent Steam Distribution System: Enables precise and optimized steam delivery to autoclaves.%u2022 Advanced Automatic Drainage System: Ensures efficient condensate discharge and prevents steam leakage.%u2022 Comprehensive Waste Heat Recovery System: Maximizes the reuse of thermal energy from waste steam and condensate.Steam is the core energy in AAC Plant
