Combustion Grates

B&W Volund combustion grates provide waste flow that ensures drying, ignition, combustion, energy release and complete burn-out before the bottom ash outlet. In a waste-to-energy plant, the grate is where waste is converted into energy – the heart of the system.As such, grates are a significant focus area for us. Over the past 80 years we have supplied more than 500 combustion grates worldwide.
