Abstract: In a method for operating and controlling/regulating a power station comprising a coal-fired steam generator (11), the steam generator (11) of which is rated for the steam parameters achievable by the heat transfer onto the steam mass flow upon coal firing in the steam generator (11) carried out using combustion air, a solution is to be created, which enables the operation of coal-fired power stations rated for air operation utilizing a firing of the fuel carried out according to the oxy-fuel process in the firing chamber of the steam generator of the coal-fired power station.

Abstract: A suspension, includes a load-carrying spring having one end indirectly supported via a spring washer by a component of a vehicle body of a motor vehicle and another end indirectly supported via a second spring washer by a wheel support assembly of the motor vehicle. Disposed at the one end of the load-carrying spring is a cup-shaped receptacle, and at the other end an abutment which has a stop surface. A slave spring is arranged in coaxial relationship to the load-carrying spring and has one end received in the receptacle and another end intended for engagement with the stop surface of the abutment. The receptacle and/or the abutment has a radially outwardly extending support ring for at least partially engaging behind the respective one of the spring washers at a side distal to the load-carrying spring to form a pre-fabricated unitary structure with the load-carrying spring.
