Abstract
A helical coil of tubing is disposed in a furnace for heat transfer fluid to circulate therethrough and absorb heat. The upper side of each coil loop is connected to a vent system which transports a portion of the circulated fluid. The vent system is continuously flushed of vapors and air which might otherwise be trapped in the tubing. The lower sides of the coil loops are connected to a drain system through which fluid flows continuously during heater operation to keep the drain clean of settlings.
