摘要:
A continuous steam generator with a circulating atmospheric fludized-bed chamber is defined by encircling walls essentially on all sides, comprised of gas-permeable tubular walls provided with essentially vertical tubes, and comprises at least one funnel in its lower region. The turbulence combustion chamber has at one essentially vertically arranged heating surface provided with vertical tubes, said heating surface comprises of a welded tube-web-tube combination, and a water/steam working medium flows through the tubes of the encircling walls and the heating surface. All of the tubes of the encircling walls and the heating surface are embodied as evaporator heating surfaces and are mounted in parallel for the circulation of the entire working medium to be evaporated. In addition, all of the tubes of the encircling walls have an inner smooth surface, and the heating surface extends between the bottom of the combustion chamber or the upper edge of the funnel, and the top of the combustion chamber.
摘要:
A load-break switch or load disconnecting switch with a spring-type over-center device whose axis actuates a switching means drive, preferably a switching shaft, includes a lever actuated by a magnet, wherein the magnet moves the lever along a path of movement, wherein the lever moved along this path of movement initially causes an uncoupling of the over-center device axis from the switching means drive and during the further travel along the path of movement the lever actuates the switching means drive which results in an "off" position of the load-break switch, and the lever subsequently again effects a coupling between the over-center device axis and the switching means drive.
