摘要： Methods of reducing emissions levels during upset periods such as startup are disclosed for use with a dry scrubber desulfurization system. A dry calcium hydroxide powder is injected into the gas flowpath and hydrated in the spray dryer absorber. The resulting hydrated powder is then deposited on the filter bags in the baghouse. This can be done at lower temperatures than the spray dryer absorber would otherwise be operable, enabling desulfurization to occur earlier in the combustion process, such as during startup of a cold combustion system at ambient temperature. The operation of the combustion system can also be backed up, made up, trimmed, or augmented depending on various operating scenarios.

摘要： 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.

摘要： A dual-exposure heat absorption panel is disclosed, which can be used in a solar receiver design. Generally, the heat absorption panel includes a tube panel through which a heat transfer fluid is flowed to absorb solar energy from heliostats that are focused on the tube panel. A structural support frame surrounds the tube panel. A stiffener structure runs across the exposed faces of the tube panel. The headers and other support structures on the periphery are protected by use of a heat shield. Different tube couplings are possible with this structure, as well as different stiffening structures at the headers. The heat shield can be shaped to create an open space, permitting focusing of sunlight on the edge tubes as well. A curtain can be used as an additional heat shield in certain scenarios.
