В проточных парогенераторах такого типа трубы образуют вместе стенки топочной камеры и несут горелки для ископаемого топлива. Трубы часто снабжены на их внутренней стороне образующими многозаходную резьбу ребрами и включены параллельно друг другу для протекания средства охлаждения. Внутренний диаметр труб является функцией частного, а точки, определенные в системе координат парами значений внутреннего диаметра труб и частного, лежат между кривой и прямой. При этом для образования частного служит суммарный весовой расход всех труб при 100%-ном парообразовании, деленный на периметр газохода в горизонтальном сечении через топочную камеру, при этом четыре определенные точки лежат на кривой, которая является постоянно нарастающей. Применение этой системы является выгодным также для проточных парогенераторов с номинальными мощностями значительно ниже 500 МВт.In flow-type steam generators of this type, the tubes form together the walls of the combustion chamber and carry burners for fossil fuels. The pipes are often provided with ribs on their inner side that form multiple thread threads and are connected parallel to each other for the flow of cooling means. The internal diameter of the pipes is a function of the quotient, and the points defined in the coordinate system by pairs of values of the internal diameter of the pipes and the quotient lie between the curve and the straight line. At the same time for the formation of private serves the total weight flow of all pipes at 100% steam generation, divided by the perimeter of the duct in horizontal section through the combustion chamber, with four specific points lie on the curve, which is constantly increasing. The use of this system is also advantageous for flow-through steam generators with nominal capacities well below 500 MW.
