Abstract
Biomass gasification manufacturers are beginning to market 5 to 100 kW capacity gasifiers (e.g., Community Power Corporation (CPC), Littleton, CO and gasifier experimenters kit (GEK), AllPower Labs, Berkeley, CA) for producing electricity and synthetic gas (syngas). These gasifiers operate at 900 to 1000 °C, consuming 1.3 kg of biomass per hour for every kW power output. This corresponds to approximately 3 dry metric tons of biomass per day for a 100 kW gasifier. These types of small gasifiers have shown promise for rural economic development. While these systems run on biomass, inclusion of as much as 30 percent coal will bring down the biomass requirement significantly and increase the total fuel available, allowing for greater application of these systems. However, incorporating coal into these types of small scale biomass gasifiers presents an unknown that will need to be addressed and tested before it can be accepted. This paper presents technical and nontechnical challenges associated with cogasification of coal and biomass mixtures.
