Abstract
A combustion system and method for liquid fuels includes atomizing the liquid fuel, withdrawing heated air from an enclosure which is to be heated by the fuel, contacting the atomized liquid fuel with the heated air which is at a temperature sufficient to instantaneously vaporize the fuel and in a quantity sufficient to form a combustible mixture with the vaporized fuel, and burning the combustible mixture to heat the enclosure. In addition, a dual fuel system is disclosed which is capable of using either the aforementioned liquid fuel system and method or a natural gas combustible mixture.
Claims13
A combustion system adapted to heat an enclosure, said system comprising:
- combustion burner means for supplying heat to said enclosure,
- first conduit means connected to said burner means for supplying a combustible mixture of an oxidizing gas and fuel to said burner means,
- injection means for discharging finely atomized liquid fuel to said first conduit means,
- second conduit means between said enclosure and said first conduit means for supplying heated oxidizing gas from said enclosure to said first conduit means adjacent said injection means,
- control means for controlling the temperature and quantity of the oxidizing gas supplied from said second conduit means such that the oxidizing gas vaporizes the liquid fuel atomized by the injection means and forms said combustible mixture, and
- heating means for supplying additional heat to the gas passing from said enclosure to said second conduit means.
A combustion system adapted to heat an enclosure, said system comprising:
- combustion burner means for supplying heat to said enclosure,
- first conduit means connected to said burner means for supplying a combustible mixture of an oxidizing gas and fuel to said burner means,
- injection means for discharging finely atomized liquid fuel to said first conduit means,
- second conduit means between said enclosure and said first conduit means for supplying heated oxidizing gas from said enclosure to said first conduit means adjacent said injection means,
- first control means for controlling the temperature and quantity of the oxidizing gas supplied from said second conduit means such that the oxidizing gas vaporizes the liquid fuel atomized by the injection means and forms said combustible mixture,
- second injection means for injecting a combustible mixture of a second fuel and an oxidizing gas into said first conduit means, and
- second control means for selectively supplying either the combustible mixture of the first mentioned fuel or the second mentioned fuel to the burner means.
A method of heating an enclosure comprising the steps of:
- elevating the temperature of the enclosure,
- forming an atomized liquid fuel,
- removing a portion of an oxidizing gas from said heated enclosure,
- contacting said atomized liquid fuel with said heated oxidizing gas,
- said oxidizing gas being further heated before contact with said atomized liquid fuel,
- controlling the quantity and temperature of the gas removed from said enclosure so as to form a combustible mixture with said fuel and vaporize said atomized liquid fuel, and
- burning said combustible mixture to heat said enclosure.
