| 181 | FRAC WATER HEATING SYSTEM AND METHOD FOR HYDRAULICALLY FRACTURING A WELL | US14169690 | 2014-01-31 | US20140144393A1 | 2014-05-29 | Ronald L. Chandler |
| The present invention overcomes many of the disadvantages of prior art mobile oil field heat exchange systems by providing an improved frac water heating system. The present invention is a self-contained unit which is easily transported to remote locations. In one embodiment, the present invention includes a single-pass tubular coil heat exchanger contained within a closed-bottom firebox having a forced-air combustion and cooling system. In another embodiment, the present invention includes multiple, single-pass heat exchanger units arranged in a vertically stacked configuration. The rig also includes integral fuel tanks, hydraulic and pneumatic systems for operating the rig at remote operations in all weather environments. In a preferred embodiment, the improved frac water heating system is used to heat water on-the-fly (i.e., directly from the supply source to the well head) to complete hydraulic fracturing operations. The present invention also includes systems for regulating and adjusting the fuel/air mixture within the firebox to maximize the combustion efficiency. The system includes a novel hood opening mechanism attached to the exhaust stack of the firebox. | ||||||

| 183 | FRAC WATER HEATER AND FUEL OIL HEATING SYSTEM | US13797694 | 2013-03-12 | US20130189629A1 | 2013-07-25 | Ronald L. Chandler |
| An accessory heat exchanger unit for heating the fuel oil used by the frac oil heater system of the invention prior to combustion. The accessory heat exchanger unit receives and distributes the fuel oil through a plurality of heat exchanger tubes prior to directing the oil to the combustion chamber. The unit also includes an inlet for receiving heated treatment fluid from the frac water heater system of the present invention. The heated treatment fluid passes over the plurality of heat exchanger tubes of the accessory heat exchanger unit prior to being directed to the outlet of the accessory heat exchanger unit. By heating the fuel oil prior to combustion, the accessory heat exchanger unit greatly improves the viscosity and flow rate of the fuel oil, thereby allowing cheaper, less cold-tolerant grades of fuel oil to be used in extreme cold climates with no degradation in the operation of the frac water heater system of the present invention. | ||||||
