Abstract:
1. A gasification system, comprising: a gasifier having an inlet section configured to receive a biomass feedstock and air, a reactor section configured to gasify a mixture of the biomass feedstock and the air to generate a producer gas, and an outlet section configured to output the producer gas from the reactor section; a heat exchanger system coupled to the outlet section of the gasifier, wherein the heat exchanger system is configured to recover heat from the gasifier by transferring heat to a fluid to create a heated fluid; a dryer configured to dry the biomass feedstock prior to delivery into the gasifier, wherein the fluid comprises a dryer exhaust from the dryer, and the heat exchanger system is configured to heat the dryer exhaust to create a heated dryer exhaust; and a gas engine configured to combust the producer gas from the gasifier to produce energy, wherein the gasification system is configured to mix the heated dryer exhaust with an engine exhaust from the gas engine to create an exhaust mixture of the heated dryer exhaust and the engine exhaust, and to reduce a temperature of the engine exhaust.
