FIELD: heat power engineering. ^ SUBSTANCE: steam generator module comprises housing chamber for supplying fluid, chamber for discharging fluid, tube bank , top and bottom tube plates. The distance grid with the skirt provided over periphery underlies the bottom tube plate and is mounted in the chamber for discharging fluid. The distance grid is made of a ring. The diameter of the inner tubes of the tube bank from the distance grid to the top of the tube plate is greater than that of the inner tube. The diameter of the inner tube in the peripheral section that passes through the ring within the height of the chamber for discharging varies from the diameter greater than the diameter of the inner tube to the outer diameter of the inner tube. ^ EFFECT: enhanced efficiency. ^ 2 dwg |
