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.
