Direct Combustion - an overview | ScienceDirect Topics

Direct heat systems are those in which the producer gas is burnt directly in furnace or boiler. The advantage of this as compared to direct combustion of biomass is in obtaining controlled heating and higher flame temperatures than those obtainable otherwise. Because of direct burning, the gas quality is less critical than is shaft power systems and consequently they are less demanding on cooling and …

The higher the AFUE rating, the more efficient the unit is. For example, a furnace with an AFUE of 80 converts 80% of the fuel to heat and loses 20% in the combustion process, where a furnace with an AFUE of 90 converts 90% and only loses 10%.
