NON-DRIVEN DIRECT-FLOW HYDRAULIC WATER HEATER Russian patent published in 2010 - IPC F24J3/00 

FIELD: heating systems.

SUBSTANCE: invention refers to heat engineering and can be used for water heating for industrial and domestic needs. In order to solve the assigned task, there proposed is non-driven direct-flow hydraulic water heater consisting of housing, in which there are longitudinal slot holes located tangentially to inner surface of housing and the orientation of which coincides with water movement direction, water drain cock, cylinder with upper inlet and lower outlet annular connection pipes. Inlet connection pipe is made in the form of rectangular nozzle inlet; on internal surface of cylinder and external surface of housing there provided are opposite diametrical partitions so that the channel is formed, which consists of in-series located orifices; distance L₁, L₂, …L_n between diametrical partitions is decreased in direction of outlet branch pipe; longitudinal slot holes are made in housing before lower annular branch pipe and in number of one hole - opposite internal cavity of upper annular branch pipe; internal cavity of housing is sealed on the side of both annular branch pipes with covers; additional branch pipe having water drain cock is made in cover adjacent to lower annular branch pipe.

EFFECT: reducing power consumption, simplifying the design, increasing serviceability.
