Tubular heat exchanger

liquid/liquidvaporization

It mainly adopted in high temperature, high pressure, and cryogenic, vaporizing, big temperature difference work conditions. Such as flare gas vaporizer, liquid oxygen and liquid Nitrogen vaporization, sulfur tail gas and flue gas treatment etc. Advantage (1) The heat transfer coefficient is increased. According to the previous thermal performance test results of floating coil type positive displacement heat exchanger, the average heat transfer coefficient K of floating coil type heat exchanger is 1.40 and 1.31 times of the new horizontal and vertical positive displacement heat exchanger respectively under the same heat medium flow rate. In addition, the floating coil is usually made of copper tube with small diameter and wall, which makes the heat transfer coefficient in the basic formula lower than that in the conventional formula δ/λ The value decreases, and thus increases the K value to a certain extent (2) The volume utilization ratio is improved. The heat exchange coil of floating coil heat exchanger can be close to 100 mm from the bottom of the container. The special structure of the heat exchanger can eliminate the non cold water area, and the effective heat storage volume can reach 95% ~ 100%, which greatly improves the volume utilization rate of the heat exchanger.
