  • Patent number: 10589226
    Abstract: The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for reducing and/or eliminating various liquid discharges from one or more emission control equipment devices (e.g., one or more wet flue gas desulfurization (WFGD) units). In another embodiment, the method and apparatus of the present invention is designed to reduce and/or eliminate the amount of liquid waste that is discharged from a WFGD unit by subjecting the WFGD liquid waste to one or more drying processes, one or more spray dryer (or spray dry) absorber processes, and/or one or more spray dryer (or spray dry) evaporation processes.

  • Patent number: 4273481
    Abstract: An automatic hydraulic stop for use with a numerical control machine and cutting tool. The stop senses the distance to a work piece, limits the depth of penetration of the tool into a work piece and provides protection for inadvertent travel of spindle of the numerical control machine beyond a projected point.
