<p>The thermal efficiency of fixed bed ash-slagging coal gasifiers is improved by recycling by-product organic liquids including tar, oils and phenols to the gasifier. By choosing a suitable point of injection above the raceway within the fuel bed complete gasification of by-products is achieved, methane formation can be enhanced and thermal efficiency is increased. These benefits are obtained without significantly increasing oxygen consumption.</p> |
