The ICAVI Reciprocating Grate combustion system was developed to provide efficient and controlled combustion of different biomass fuels. Its operation is based on an intermittent forward-backward movement of the grate, continuously stirring the fuel as it advances along the combustion surface. This movement promotes fuel bed homogenization and improves energy utilization. The combustion process takes place in four distinct stages along the grate: fuel drying, volatile combustion, fixed carbon combustion, and ash cooling. The grate is designed with an inclined surface to provide a more uniform fuel flow, contributing to combustion stability and improved thermal performance. Combustion air is evenly distributed through independent sections, ensuring proper airflow across the entire grate area while providing adequate cooling for efficient operation. This technology is recommended for industrial applications requiring operational reliability, stable combustion, and the use of different biomass fuels. The vibrating motion is transmitted to the grate through a mechanical assembly consisting of an eccentric shaft and a rigid connecting bar, allowing vibration frequency and intensity to be adjusted according to fuel characteristics. The air distribution system is designed with independent chambers beneath the grate, ensuring proper combustion control across different bed zones and improving thermal efficiency. One of the main advantages of the ICAVI Vibrating Grate is the uniform distribution of fuel over the grate, significantly reducing ash sintering formation and contributing to greater operational stability, reduced maintenance requirements, and improved combustion performance. This technology is recommended for applications requiring high operational flexibility and the use of biomass fuels with varying physical characteristics and moisture content.
