Two types of vaporizing: 1.Water Bath Vaporizers
As the propane picks up the heat it is transformed from a liquid to a vapor. The rate this occurs is based on the flow rate of the propane entering the bath and the amount of heat being introduced. All of these functions are controlled by a programmable logic control (PLC) located in the control cabinet of the unit. Safety features keep the system functioning properly and both input and output pressures and temperatures are monitored by the PLC.
A water bath vaporizer uses an insulated “Bath” or enclosure that contains several tubes through which propane flow is directed. The bath is filled with a heat transfer solution (HTS) that is heated by a burner assembly at one end of the unit. The HTS is circulated around these tubes by a small circulating pump to keep the heat evenly distributed within the bath. Propane enters the tubes as a liquid and absorbs heat from the “bath” enclosure around the tubes.
