At a large biogas plant in Belgium, the process air had to be removed and then reused in a subsequent drying process. These 2 fans were placed between the chemical air scrubber and a biobed.
We were recently asked by a customer if we could provide a solution for an installation to extract process air from a chemical air scrubber into a drying process. From the biogas plant, they were extracting the hot air and later wanted to use it to dry liquid digestate fermented out on a belt dryer into a dry organic manure pellet.
These heavy-duty centrifugal fans are partly made of stainless steel 304 sheet material, only the motor seat is made of normal steel and is coated. The customer was looking for a fan that could move 80,000 m3/h of air with a back pressure of only 800 pascals. The process air temperature could reach a maximum of 30° Celsius. The fan is equipped with a split housing to allow easy maintenance. The fan features backward-curved profiled blades. This high-efficiency impeller enabled us to use an electric motor of only 45kW and realise a power consumption of only 31kW.
