CONTACT HEAT EXCHANGER Russian patent published in 1994 - IPC

FIELD: heat power engineering. SUBSTANCE: heating heat-transfer agent enters housing 1 in two flows through tangential branch pipes 2 and 3 where flows are sprinkled beforehand. Water supplied through sprinkling device 11 gets in contact with flows of heating heat agent and moves over complex spiral-shaped trajectory. Shells 5 and 6 first of which is connected to branch pipe 2 are located coaxially along axis of housing 1 and have effect on forming the trajectory of motion of heating agent flows. Located on housing in zone of shells is circular chute 10 accumulating water which is then flows to branch pipe 2. EFFECT: enhanced efficiency. 1 dwg
