CYMIC boilers - using CFB technology

Efficient combustion, low emissions and high steam parameters. The key element in the CFB boiler is the cyclone. CYMIC boilers use high-efficiency cylindrical cyclones constructed of membrane walls covered by a light refractory for erosion protection. No hot expansion joints between the furnace and the cyclone are needed. High steam parameters are
