Abstract: In a squeeze film damper bearing device, a pair of annular projections projecting toward an inner periphery of a bearing retaining member are provided on an outer periphery of opposite end parts in an axial direction of an outer race. When a load in a radial direction acting on a rotating shaft is less than a predetermined value, a state in which an extremity face of the annular projection is not in contact with the inner periphery of the bearing retaining member is maintained. When the load in the radial direction acting on the rotating shaft is the predetermined value or greater, the extremity face of the annular projection is in contact with the inner periphery of the bearing retaining member. The annular projection does not abut against the inner periphery of the bearing retaining member at a time other than when a large load is inputted.

Abstract: A mercury removing device includes a gasification unit that converts a non-gaseous-mercury-chlorinating agent, which is non-gaseous at room temperature and normal pressure, into gaseous-mercury-chlorinating agent by heating the non-gaseous-mercury-chlorinating agent with heat of hot air generated by using the exhaust gas or hot air generated by using an air heater installed in a flue that conveys the exhaust gas. The gaseous-mercury-chlorinating agent produced in this manner is supplied to the exhaust gas in the flue.
