The natural circulation steam generator implemented by Kablitz was designed as a combination of water tube and smoke tube evaporator. In this case, a second drum was added to the smoke tube. This upper drum is required due to the steam pressure and the high boiler output (for smoke tube boilers) in order to ensure a sufficiently large volume.

A coal-fired plant may benefit from a biomass conversion for several reasons, including coping with the rising cost of fossil fuels and dealing with more stringent emissions regulations. If you are considering this change for your plant, it's essential that you consider the possible effects of biomass fuels on your existing boiler and systems.
