Abstract
A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.
Claims20
A flameless combination heater for heating air and a heater fluid, said flameless combination heater comprising:
- a prime mover, said prime mover comprising circulating engine coolant and engine exhaust;
- a heater fluid system, said heater fluid system comprising heater fluid, a first heat exchanger configured to transfer heat from the engine coolant to the heater fluid and a second heat exchanger configured to heat the heater fluid, said second heat exchanger driven by the prime mover;
- an air moving system for moving heated air, said air moving system comprising a fan and a third heat exchanger;
- and
- a three-way variable valve configured to control distribution of relative amounts of heated heater fluid to at least one of a heating fluid hose and the third heat exchanger, wherein
- the amount of heated heater fluid sent to the fluid hose and the third heat exchanger is determined based on a predetermined position of the three-way variable valve, and
- if the predetermined position is set such that all the heater fluid is sent to the third heat exchanger, then substantially all of the heat generated from the heated fluid is output from said flameless combination heater as heated air.
A flameless combination heater for heating air and a heater fluid, said flameless combination heater comprising:
- a prime mover, said prime mover including circulating engine coolant and engine exhaust;
- a heater fluid system, said heater fluid system comprising heater fluid, a heater fluid pump, a heater fluid reservoir, a first heat exchanger for transferring heat from the engine coolant to the heater fluid and a dynamic heater for heating the heater fluid, said dynamic heater and said heater fluid pump driven by the prime mover;
- an air moving system configured to move heated air, said air moving system comprising a fan and a second to air heat exchanger, said fan driven by the prime mover;
- and
- a three way variable valve configured to control distribution of relative amounts of heated heater fluid and the heated air by controlling distribution of the heated heater fluid,
- wherein the heated heater fluid is directed to at least one of a heating fluid hose and the second heat exchanger,
- the amount of heated heater fluid directed to the heating fluid hose and the second heat exchanger is determined based on a predetermined position of the three-way variable valve, and
- if the predetermined position is set such that all the heater fluid is sent to the second heat exchanger, then substantially all of the heat generated from the heated fluid is output from said flameless combination heater as heated air.
