Taguchi approach for co-gasification optimization of torrefied biomass and coal.
This study employs the Taguchi method to approach the optimum co-gasification operation of torrefied biomass (eucalyptus) and coal in an entrained flow gasifier. The cold gas efficiency is adopted as the performance index of co-gasification. The influences of six parameters, namely, the biomass blending ratio, oxygen-to-fuel mass ratio (O/F ratio), biomass torrefaction temperature, gasification...
متن کاملEvaluation of Biomass Introduction Methods in Coal Co-Gasification
Heightened concerns over the amount of carbon emitted from coal-related processes are generating shifts to the application of biomass. In co-gasification, where coal is gasified along with biomass, the biomass may be fed together with coal (cofeeding) or an independent biomass gasifier needs to be integrated with the coal gasifier. The main aim of this work is to evaluate the biomass introducti...
متن کاملCase Studies for Biomass/coal Co-gasification in Igcc Applications
Employing biomass as a feedstock to generate fuels or power has the advantage of being carbon neutral or even becoming carbon negative, if carbon is captured and sequestrated. However, there are challenges facing the effective utilization of biomass wastes: (a) biomass supply is limited and varies with the seasons, (b) biomass density is low and expensive for long-distance transportation, and (...
متن کاملSub Topic: Coal and Biomass Combustion and Gasification
Results are reported from recent tests where hydrothermal flames spontaneously ignited in a Supercritical Water Oxidation (SCWO) Test Cell. Hydrothermal flames are generally categorized as flames that occur when appropriate concentrations of fuel and oxidizer are present in supercritical water (SCW); i.e., water at conditions above its critical point (218 atm and 374 °C). A co-flow injector was...
متن کاملKinetic Modeling of Biomass Gasification and Combustion
This review critically examines char conversion kinetics in oxidizing or reducing atmosphere. In kinetic analysis the devolatilization of biomass and the conversion of char are usually investigated by means of separate experiments, although some kinetic models are also available of biomass combustion. The large majority of the char conversion kinetics consists of a global reaction with activati...
