Heat exchange section HORIZONTAL fire-tube hot water boilers

摘要

The invention relates to fire-tube boilers with a flame tube is integral with the boiler body and auxiliary fire tubes, which can be used in heating and water-supply systems of various residential, and industrial plants. The task and technical result of the utility model is to increase the efficiency of the heat exchange section of the fire-tube boiler, reducing the rate of deposition of deposits on the outer surface of the flue pipes and reducing sludge deposition rate of the combustion products inside the flue pipe. The technical result is achieved in that the heat exchange part of the horizontal fire-tube boiler comprises a cylindrical body with end tube plates, inside which are placed the flame tube and the flue tube fixed in openings of tube plates, wherein the inner surface of at least part of the smoke tube arranged below level of the flame tube are formed multistart, helically directed groove.
