Abstract: Various embodiments of a system for the removal of particulate emissions from an electric generating unit are provided, comprising: a gas producer; a primary particulate collector unit including: a primary collection hopper field each including at least one primary collection hopper, wherein each primary collection hopper includes a primary collection hopper outlet, each primary collection hopper outlet fluidically connected to a particulate discharge duct; a flue duct inlet oriented upstream of the at least one primary collection hopper field; a flue duct outlet oriented downstream of the primary collection hopper field; wherein the gas producer is fluidically connected to the primary particulate collector unit by a flue duct; and a particulate recirculation duct fluidically connected at a first end to the primary collection hopper and/or the particulate discharge duct, and fluidically connected at a second end to the flue duct upstream of the primary particulate collector unit.

Abstract: The present disclosure relates to fluidized-bed boilers and methods for controlling bed agglomeration that can occur when biomass containing high amounts of phosphorus is used as fuel. Iron-containing compounds, such as iron oxide, are added to the fluidized bed to tie up the phosphorus in a form that will not react under typical operating conditions for fluidized-bed boilers.

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.
