Sometimes referred to as a weir bath heater, this is a slight variation of a traditional water bath heater that does not utilize a process coil. This type of heater is most commonly used as a direct fired reboiler for amine and glycol solutions. The bath vessel contains a fire-tube and a weir at the end of the fire-tube. The process fluid is circulated through the bath vessel in direct contact with the fire-tube. After the process fluid is heated, it falls over the weir where the return line sends it back to the process user.
