Abstract
A flameless heater produces hot dry air utilizing hydraulic heat-transfer fluid as a heat transfer medium. The heater is powered preferably by a natural gas engine. The process begins with the natural gas engine producing rotary power which drives a hydraulic pump which directs the heat-transferring fluid through a dynamic heat generator to heat the fluid via an internal friction process. The heated fluid is subsequently circulated through a heat exchanger where a hydraulically-powered fan blows ambient air through to be heated. The heat exchanger also extracts heat from the exhaust and coolant system portions of the engine to further heat the air. The produced dry hot air may be used for general heating. It is envisioned that engines which utilize other fuel sources such as diesel, gasoline, steam, or the like could be utilized with equal effectiveness.
