  • BIOMASS CONVERSION REACTOR POWER GENERATION SYSTEM AND METHOD
    Publication number: 20140175803
    Abstract: Methods and systems for generating power using syngas created using biomass gasification are provided. Exemplary power generation systems include a biomass dryer for receiving biomass, a biomass conversion reactor (either a biomass gasifier or a steam-biomass reformer) for receiving the dried biomass and generating syngas therefrom, and an external combustor for combusting the syngas and heating a working fluid to drive a turbine connected to an electrical generator. The external combustor includes a heat exchanger element for transferring heat from combustion of the syngas into the working fluid, while maintaining the working fluid isolated from the syngas and from syngas combustion products.
