The key to cofiring wood or other biomass with coal in existing power stations is fuel management. Fuel management includes the procurement, receiving, processing, storage, and blending of the biomass with coal. Procurement options may include the purchase of lower cost biomass fuels, receipt of subsidies to make capital modifications to cofire biomass {open_quotes}waste{close_quotes} fuels or receive tipping fees where biomass waste disposal options for a particular area are expensive. Biomass receiving options include delivery methods, unloading, measurement, and inspection. Processing options are associated with screen types, drying systems, final particle size required, and associated questions of fuel supply reliability. Issues include the ability of the coal yard to accept this processing operation, handling convenience, traffic patterns, staffing requirements, and ultimately the cost of fuel at the burner. Issues associated with storage include locating the facility, managing dust, managing moisture pick-up, and managing runoff. Blending options include pre-blending or designing a system to blend the fuels as they are transported from the coal yard to the bunkers. This paper reviews the major decisions that have to be made, and discusses some of the options available. It draws upon existing experience in cofiring systems to achieve a low cost, high reliability system to use biomass at coal-fired electricity generating stations.
