ABSTRACT OF THE DISCLOSURE The system utilizes a heat engine which provides shaft power and heat such as a conventional diesel engine in which part of the shaft power drive a pump for fluid to be heated; for example, a cryogenic liquid. The engine heat is used to heat and/or vaporize the cryogenic liquid in a heat exchanger. The heat available from the engine for transfer to the liquid to be vaporized is proportional to the power level of the engine. The heat required to heat the fluid to a desired temperature is proportional to the flow rate of the cryogenic liquid. By providing a loading on the engine which is proportional to the fluid flow rate, a sufficient amount of heat is provided to effect complete vaporization of the liquid, the amount of heat being directly propor- tional to the flow rate of the liquid. The loading of the engine can be accomplished by a power absorbing hydraulic drive connected to the engine shaft with the hydraulic medium used to drive the cryogenic liquid pump. A rotary hydraulic drive and multi-section rotary driven fluid pump is provided to achieve vibration free, smooth operation in simplified, closed loop hydraulic drive circuit. A dual rotary system is also disclosed.
