Heatec steam generators eliminate the need for a boiler. They produce steam by heating water with hot thermal fluid from a thermal fluid heater. The hot thermal fluid circulates through tubes of the steam generator, heating water surrounding the tubes and converting it into steam.
Unlike a boiler, tubes in the steam generator never get hotter than the thermal fluid flowing through them. This minimizes explosion hazards associated with boilers. It also eliminates the need for a boiler tender, who must be present when a boiler is in operation.
Steam is used for temporary heating hookups where use of hot oil is not practical. For example, steam is used at asphalt terminals to heat tank cars filled with asphalt so they can be unloaded.
