Water cooling makes it possible to use widely differing biofuels – wet or dry – in the same oven. Thus, you can always use the fuel type that is available – or whatever is most economical in the current situation. Water cooling allows you to determine the oven temperature to match the fuel type being used. In other words, you can raise the oven temperature when firing with wet fuel – and lower it when the fuel is dry. Justsen revolutionized biofuel plants by developing the water-cooled grate system. This has obvious advantages: It is not necessary to differentiate between fuel types, it ensures the least possible impact on the environment, and it eliminates slag formation. And, of course, you can fully utilize the heat from the cooling water. Plants with water-cooled grate systems are flexible, efficient and extremely reliable.
