A wet packed bed scrubber-based producer gas cooling–cleaning system

Biomass gasifiers are playing an increasing role as decentralized energy sources in the rural areas of India. When used for power generation through internal combustion engines, or for certain thermal applications requiring a clean flue gas, it is necessary to cool biomass-based producer gas to ambient temperature, and clean it of tar and particulates before it can be used as a fuel. This paper describes the development and evaluation of a compact, wet packed bed scrubber-based producer gas cooling and cleaning system, suited for small-scale applications.
