A gasifier is provided gasify multiple fuels. The gasifier is configured to include a first gasification zone for gasifying a high-calorific-value feedstock with an oxidant. The gasifier is configured to substantially consume the oxidant within the first gasification zone. The gasifier further includes a second gasification zone for gasifying a low-calorific-value, high-oxygen-content feedstock. The high-calorific-value fuel may be coal and the low-calorific-value fuel may be biomass.
