A high-temperature steam-water heat exchanger is composed of heat-transfer corrugated plates and a frame. The plates are clamped between a fixed pressure plate and a movable pressure plate using bolts, forming numerous flow channels inside the heat exchanger. Rubber gaskets are used for sealing between adjacent plates.
A spiral plate heat exchanger is a type of heat exchange equipment suitable for heat transfer between steam-steam, steam-liquid, and liquid-liquid media. It is widely used in industries such as chemical engineering, petroleum processing, solvent processing, pharmaceuticals, food production, light industry, textiles, metallurgy, steel rolling, and coking.
A shell-and-tube heat exchanger is a general-purpose process equipment for heat exchange operations. It is extensively applied in industrial sectors including chemical engineering, petroleum, petrochemicals, electric power, light industry, metallurgy, nuclear energy, shipbuilding, aerospace, and heating supply.
The pressure plates are equipped with nozzles for connecting the equipment to external pipelines. The heat-transfer plates are pressed from thin corrosion-resistant metal sheets, with corner holes punched at the four corners for medium inlet and outlet, and hanging holes at the top and bottom.
In a floating-head heat exchanger, one end of the tube sheet is fixed to the shell, while the tube sheet at the other end can float freely inside the shell. Both the shell and the tube bundle are free to expand thermally; therefore, when there is a large temperature difference between the two media, no temperature difference stress will be generated between the tube bundle and the shell.
A volumetric heat exchanger is a widely used type of heat exchanger, mainly consisting of a shell, a steam coil assembly, steam inlets and outlets, and cold/hot water inlets and outlets.
Selection Method for Volumetric Heat Exchangers
Calculation-Based Selection: The selection is completed by calculating the required heat transfer area.
Experience-Based Selection: For simple applications in production, the model and specification can also be selected based on experience. However, in most cases, detailed calculations are required to complete the selection.
When selecting a volumetric heat exchanger, the hourly water consumption should be considered first. Secondly, a buffer volume should be taken into account to prevent the hot water temperature from fluctuating (becoming alternately hot and cold). Generally, the buffer volume is 1/4 of the hourly water consumption, or it can be determined based on a 10–15 minute buffer water volume.
