A route for turning existing boilers into biomass gasifiers
Ten years of operating the 2–4 MW Chalmers research gasifier and the 20 MW GoBiGas biomethane plant, distilled into a route to commercial use. Two findings carry it: constituents of the biomass ash itself act as a catalyst for the process, and with coated heat exchangers ordinary fluidized-bed boilers can be retrofitted into gasifiers. The paper estimates that Sweden's existing fluidized-bed boilers alone correspond to a jet-fuel capacity of about 10% of current global consumption.
