Abstract
A turbine produces in an improved gasification process a stream of pressurized air, which is cooled and further compressed by a cooler and booster/compressor. The cooled and compressed air is humidified in a humidifier, heated by a low temperature heat source and subsequently fed into a gasification vessel in which a feedstock is gasified or partially oxidized. The humidifier may advantageously utilize wastewater to humidify the cooled and compressed air, wherein the wastewater may or may not be produced by a component in a gasification plant.
