摘要:
An electrical heating device (1) includes a housing (2, 102) having a fluid inlet (3) for the intake of a fluid to be heated into the housing (2, 102) and having a fluid outlet (4) for the discharge of the fluid from the housing (2, 102). A flow channel (5) for the fluid is formed between the fluid inlet (3) and fluid outlet (4), and at least one heating instrument (6, 105, 205) extends into the flow channel (5) in the housing (2, 102). This heating instrument has a sleeve (7, 207) that surrounds an interior of the heating instrument (6, 105, 205) in a fluid-tight way. At least one heating element (8, 208) is arranged in the sleeve (7, 207), and at least one sensor element (9, 109, 209) is arranged in the sleeve (7, 207) for monitoring the temperature of the at least one heating element (8, 208).

A design and manufacturing technique for a “Long Heat Exchanger”, a counter-flow heat exchanger transfer up to 100% of heat and temperature between two fluids (gas or liquid). Inner “Core” of heat conductive material capable of manufacture in continuous lengths, may be coiled, cut and formed to shape. 100% of conductive material making up core is a heat transfer surface, allowing minimum material design for chosen transfer efficiency. “Core” has integral fins allowing overall device to be bent in a radius without deforming. Outer channel volume and core fins surface area may be sized to match different density fluids.

Mobile water heating systems for producing hot water are disclosed herein. In one embodiment, a mobile water heating system includes a water heater having an oval-cylindrical shape. The water heater includes a shell, a lid and a water reservoir having a screen. A first heating coil and a second heating coil can extend between the screen and a first cone and a second cone, respectively. A first burner and a second burner can be configured to mix and combust fuel and air and direct the resulting flames through the heating coils. Pall rings can at least partially fill an interior volume of the water heater and the combustion of the fuel and air can heat the heating coils and the pall rings. Water can be heated by being directed through the heating coils and through a water manifold positioned to spray water on the pall rings.

The invention relates to an electric heater comprising a fluid-conducting housing, in which at least one, preferably helical, heating unit, preferably a wire resistance heating element, is accommodated. The heating unit can have a tubular outer body, in which a heating element electrically contacted with a control circuit accommodated in an electronics housing is embedded. According to the invention, end sections of the heating unit extend in a sealed manner through the fluid-conducting housing to, and preferably into, an electronics housing. The invention further discloses a method for actuating an electric heater and to a heater that can be operated according to such a method, wherein said heater is designed with at least one resistance heating element, which acts as a temperature sensor, so that the temperature thereof can be used for actuating the heater.
摘要:
The present invention provides a method for utilizing an oil-fired heat exchange system to fracture a subterranean formation at a remote work site to produce oil and gas. The method of the present invention includes using a single-pass tubular coil heat exchanger contained within a closed-bottom firebox having a forced-air combustion and cooling system to heat the treatment fluid. 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 method of the present invention includes using an oil-fired heat exchanger system to heat water on-the-fly (i.e., directly from the supply source to the well head) to complete hydraulic fracturing operations. The method of the present invention also includes adding chemical additives and proppants to the heated treatment fluid prior to injection into the formation.

The present invention overcomes many of the disadvantages of prior art mobile oil field heat exchange systems by providing a portable heat exchange system. The present invention is a self-contained unit which is easily transported to remote locations. 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. 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 portable heat exchanger 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.
