The total heat transfer coefficient is a parameter used to measure the heat transfer resistance of heat exchanger. Increasing the flow rate between plates can improve the heat transfer coefficient, but increasing the flow rate will increase the resistance of the heat exchanger, so the power consumption of the circulating pump will be increased, which is not economical. In order to better control the resistance requirements, some measures are needed to assist. Today we will introduce the method o
When there are fibrous and large particles in the heat exchanger, the effect of backwashing is quite obvious. The purpose of backwashing can be achieved by one of the following two ways:
Loss of flow of plate heat exchanger: the pressure in the steam space of plate heat exchanger is less than or equal to the total back pressure behind the steam trap, which leads to the phenomenon that the condensate cannot be discharged in time.
