Abstract

Przepływowa wytwornica pary z pionowym ciągiem gazowym, który jest wykonany z gazoszczelnych ścian rurowych, których rury są usytuowane śrubowo lub spiralnie w dolnej części ciągu gazowego, w której znajduje się palnik na paliwo stałe, a w górnej części ciągu gazowego są usytuowane pionowo, i którego cześć dolna jest ograniczona na dolnym końcu przez dno ciągu gazowego, a którego część dolna jest ograniczona na górnym końcu za pomocą ściany poprzecznej ciągu gazowego, za pomocą utworzonego przez ściany rurowe zwężenia przekroju poprzecznego ciągu gazowego albo za pomocą krawędzi dolnej powierzchni grzejnych, umieszczonych wewnątrz ciągu gazowego, charakteryzuje się tym, że całkowita wysokość (Hges) dolnej części ciągu gazowego (4) jest ukształtowana zgodnie z proporcją, przy czym ściany rurowe (3) dolnej części (4) ciągu gazowego (2) są podzielone na jeden dolny i co najmniej jeden dalszy odcinek ściany rurowej (8,9) i rury (11) dolnego odcinka ściany rurowej (8) są wewnątrz gładkie, a rury (12) odcinka ściany rurowej (9), przylegające bezpośrednio na dolnym odcinku ściany rurowej (8) są wewnątrz ożebrowane w postaci gwintu wielozwojowego, przy czym wysokość (H1) dolnego odcinka ściany rurowej (8), w odniesieniu do całkowitej wysokości (Hges) dolnej części (4) ciągu gazowego (2) jest ukształtowana zgodnie z proporcją,Flow-through steam generator with a vertical gas passage, which is made of gas-tight pipe walls, the pipes of which are located helically or spirally in the lower part of the gas passage, in which there is a solid fuel burner, and in the upper part of the gas passage they are arranged vertically, and part of which the lower part is limited at the lower end by the bottom of the gas passage, and the lower part of which is limited at the upper end by the transverse wall of the gas passage, by the narrowing of the cross-section of the gas passage formed by the pipe walls, or by the lower edge of the heating surfaces located inside the gas passage , is characterized by the fact that the total height (Hges) of the lower part of the gas passage (4) is shaped in accordance with the proportion, and the tubular walls (3) of the lower part (4) of the gas passage (2) are divided into one lower and at least one the further section of the tubular wall (8,9) and the pipe (11) of the lower section of the tubular wall (8) are smooth inside, and the pipes (12) of the tubular wall section (9), adjacent directly to the lower section of the tubular wall (8), are ribbed on the inside in the form of a multi-start thread, where the height (H1) of the lower section of the pipe wall (8), in relation to the total height (Hges) of the lower part (4) of the gas passage (2), is shaped in accordance with the proportion,
