Are 450-degree heat exchangers made with tube bundles or U-tubes?
Thread Content
Can a tubular heat exchanger be used for heat exchange between medium-bitumen at 450 degrees Celsius, low-temperature bitumen at 330 degrees Celsius, and high-temperature bitumen at 420 degrees Celsius? :Q
It should be possible; pay attention to controlling the flow rate when selecting the model. There are no other types of heat exchangers that are more suitable than tube heat exchangers. Note: It is a floating-head tubular heat exchanger.
U-tubes can be used, as well as floating-head shell-and-tube heat exchangers
Given the high viscosity of asphalt, high-temperature asphalt flows in the tube side; therefore, it is necessary that the core can be removed from the shell side to facilitate cleaning. The tube side is equipped with straight tubes, allowing for easy cleaning.
It’s too difficult to clean clogs in U-tubes; they can’t be cleared. I want to know if shell-and-tube types can withstand 450° temperatures

These days, the term \"tube bundle\" is used less often; shell-and-tube designs are preferred in most cases
