Abstract: A float device which provides an on-demand change in tacking or planing direction without having to retrieve the float or adjust the float configuration. The float utilizes a float body and at least two longitudinal keel members oppositely disposed on the float body. In a first orientation, the first keel is submerged and the second keel is in the air and the float tacks in the first keel direction. A sharp pull on a tether line connected to the float causes the float body to roll 180 degrees such that second keel is submerged and the first keel is in the air and the float tacks in the second keel direction.

Abstract: A method of reducing the pressure drop in a downflow/upflow wet flue gas desulfurization (WFGD) system and of improving overall sulfur dioxide collection efficiency by converting the downflow/upflow WFGD system to an upflow single-loop WFGD system. The method includes the replacing of the downflow quencher and related duct work with a bypass for connecting the incoming flue gas duct with the upflow absorber, and the adding of a quenching zone in the absorber comprised of spray headers.

Abstract: This invention pertains to a single spray level within a flue gas desulfurization absorber tower. This spray level incorporates multiple headers with each header having a plurality of feeder lines connected thereto. These feeder lines extend within the flue gas flow path in an alternating and staggered configuration within the same plane. A series of nozzles are secured to each feeder line to spray a mixture onto the flue gas. Spare capacity, if required, is incorporated into the spray level.
