If a lot of heat is required, we can increase the diameter of the reactor. It is easy to provide 50kW of heat or more from a single reactor. Of course a lot depends on the type of biomass. If the burn-time must be long, we increase the height of the reactor. As Paul Anderson said, we can reach up to 2 hours or more. Again, each biomass has its own burn rate. Thanks. Paul Olivier
