U-tube heat exchanger compact structure, small size, saving the station house land area and building height (for the general area of shell and tube heat exchanger 1 / 2 Left

Right, highly reduced 30 ~ 40%). Save construction investment, ease of design layout, while running and easy operation.

Heat transfer performance, heat medium outlet temperature is low, heat utilization of high energy-saving effect is good. The high heat transfer coefficient, saving heat transfer area (TQN, TQK) soda

Heat exchanger heat transfer coefficient (K value) than the soda plate heat exchanger heat transfer coefficient of the actual use of twice as large as about 40-60% heat transfer area can be reduced.

Hydraulic characteristics of a good, hot coal, and heated the water flow resistance is small, energy-saving effect is good. U-tube heat exchanger soft condensed water discharged from low temperature (TQK) Department of

Out at 65 ¡æ below, (TQN) series at 80 ¡æ below, both seamless vapor loss, do not need to install steam trap, piping system is simple, heat loss.

U-tube heat exchanger tube soft drink than the average spacing between the shell and tube heat exchanger tube spacing between the large, each heat transfer unit size and weight of small, easy-dimensional
