SYSTEMS FOR HEATING WATER USED IN HYDRAULIC FRACTURING

摘要

A system for flameless heating of a fluid includes a hydraulic pump having an input shaft and a rotational power source coupled in torque-transmitting relationship with the input shaft of the hydraulic pump. A hydraulic fluid circuit is in fluid connection with an inlet port and an outlet port of the hydraulic pump. A water heat exchanger having a tank provided with water from a water source and a conduit provided with heated fluid from at least one of the hydraulic pump and the power source is arranged such that heat is transferred from the heated fluid in the conduit to the water in the tank. In one example, at least one valve in the hydraulic fluid circuit selectively limits output flow from the outlet port of the hydraulic pump, thereby providing resistance to pumping motion and heating the hydraulic fluid in the hydraulic pump.
