The described system utilizes a heat engine which provides shaft power and heat such as a conventional diesel engine 14 in which part of the shaft power drives a pump 11 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 10. The heat available from the engine for transfer to the liquid to be vaporized is proportional to the power level of the engine. By providing a loading on the engine which is proportional to the flow rate of the cryogenic liquid, a sufficient amount of heat is provided to effect complete vaporization of the liquid, the amount of heat being directly proportional to the flow rate of the liquid. The loading of the engine can be accomplished by a power absorbing hydraulic drive 22 connected to the engine shaft with the hydraulic medium used to drive the cryogenic liquid pump. A pilot valve operates a reversing valve connected to a ram cylinder for providing a reciprocating output to drive the actuating member of the fluid pump. A surge suppression plate interconnecting the valves, ram cylinder, and loading means into a unitary structure. <IMAGE> |
