Abstract: A dual phase fuel feeder is disclosed that can be used to provide both solid fuels and liquid fuels to a boiler, such as a fluidized bed boiler. The fuel feeder includes a sloped chute which defines a solid feedpath. Gas distribution nozzles are located at the base of the fuel feeder, and secondary nozzles are located so as to be able to distribute a liquid or particulate fuel into the solid feedpath. This permits the liquid fuel to contact the solid fuel and be carried into the fluidized bed instead of becoming suspended above the bed.

Abstract: A fossil-fuel-fired system, which includes an emissions-control-agent dispenser, a furnace, an emissions monitor and, optionally, a controller, is disclosed. The emissions-control-agent dispenser provides a prescribed amount of organic-emissions-control agent, such as, for example, an opacity-control agent to the fossil-fuel-fired system. The furnace includes an exhaust communicating with the atmosphere. The emissions monitor is capable of measuring at least one property of the flue-gas communicated through the exhaust to the atmosphere. For example, when an organic-emissions-control agent is an opacity-control agent, the emissions monitor has the capability of at least measuring opacity. When included, the controller communicates with at least the emissions-control-agent dispenser and the emissions monitor.

Abstract: The description relates to controlling slagging and/or fouling in biomass burning furnaces. Combustion of such a biomass the fuel with air produces combustion gases containing sodium and/or potassium compositions, and the combustion gases are treated by contacting the combustion gases with kaolin and aluminum hydroxide. At least one of the kaolin and aluminum hydroxide can be introduced with the fuel, in a combustion chamber, with reburn fuel or with overfire air. For fuels also high in zinc and/or heavy metals, magnesium hydroxide is introduced into the combustion chamber or following heat exchangers.
