Canadian Patent Application S.N. 270,421 Columbia Chase Corporation Abstract of the Invention An improved process for utilizing water to obtain an efficient combustion of hydrocarbon. The process composing steps of premixing some water and oil in the presence of a gas, such as steam, and thereupon sending, under pressure to the burner head, the resultant emulsion of water, oil and gas.
Description
`-` 10~2586 BACKGROUND OF THE INVENTION:
The use of water, in various quantities and forms, as an additive to provide improved combustion of hydrocarbon fuels and waste gases is old.
Such processes have been proposed for various purposes: e.g.
avoiding unsightly smoke from refinery waste-gas flares and improving the economics of home-type oil burner systems. These processes have included adding the water to the combustible as liquid, or as vapor, and in a very broad range of percentages.
Among the U.S. patents illustrative of such processes are those `-which utili~e very high levels of water (U.S.Patent 3,104,311) and very low levels of water ~U.S. Patent 3,862,819). Some patents disclose mixing of the water with the oil (Patent 3,706,942) and some use the water in the form of a vapor catalyst - often injecting the water as vapor. While some of the processes suggested in the art are probably of little value because they use too little or too much water, it may be safely assumed that, when operating at equilibrium, a substantial advantage in some combustion charac-teristics is achieved with many of the processes described in the art.

. . :,. .. , ~ : . `. ' r -` 101~2586 . .
1 Nevertheless, substantial problems remain in implementing such processes commercially. The high combustion eff~iciencies to be realized are accompanied by the use of less secondary air, This means that more water of combustion is in a given volume of stack gas and undesirably high dew points are experienced.
Simultaneously, the efficient higll-temperature process in the furnace results in a highly efficient heat transfer in a properly designed furnace. I'his Eurther decreases the amount of waste heat and also tends ~o increase the probability that a stack gas temperature will fall below its dew point.
Even when the dew point is generally maintained at a minimum practical level, any temporary f uctucation in draft conditions can cause serious condensation prob]ems in the heat transfer and stack-gas handling portions of a heating system.
What is required is a dependable, stable means to operate a water-catalyzed combustion process at something approaching a steady state. Problems relating to flame stability, to re-ignition, and even to the usual changes in draft air or in heating loads within a furnace, must be minimized. ~11 this is ideally achieved Witllout sacriEicing any oE the substantial combustion efficiency, which is attainable with H20-promoted combustion.
-lOl~ZS86 SUM~RY OF THE INVENTION:
According to the present invention there is provided a process forburning liquid hydrocarbons at high temperatures within the confines of a combustion chamber, said process comprising the steps of: (i) emulsifying said hydrocarbon with a dispersing fluid; (ii) passing said emulsified fluid under a higher pressure to a burner head and into a furnace at a lower pressure, causing said fluid to expand and disperse said hydrocarbon and (iii) simultaneously providing a water-vapor-bearing atmosphere within which said fluid is expanded, dispersed and burned.
According to the process of the present invention the dispersing fluid may be air or steam. The water-vapor-bearing atmosphere may comprise 3 to 13 % of water-vapor or steam. The water-vapor-bearing atmosphere may comprise a quantity of hydrocarbon fuel which is insufficient to support combustion.
According to the process of the present invention the emulsifying may include the step of intimately contacting some steam, water and a small portion of said fuel in a conditioning zone, effluent from said conditioning zone is then mi~ed with fuel and the resultant mix supplied to the burner head. The quantity of water fed to the conditioning zone may be equal to about 5% of hydrocarbon fuel burned in the process.
In the emulsification of the hydrocarbon, a substantial a unt of water, 5~ to 15~ by weight based on fuel, may be vigorously agitated with the expansion fluid and the fuel to be burned. This is believed to aid the emulsification of the fuel with the expansion fluid. A substantial amount, typically 5% to 20% by weight, of H20 may be contained in the vapor atmosphere into which the emulsified hydrocarbon is expanded and burned. This vapor-bearing atmosphere may be provided around the burner head OT, provided through the burner head, or provided by mixing air from a source proximate to the burner head with H20 which is contained in the dispensing fluid injected through the burner head. The H20 can include both ,` ~ -3-j_ :
.
~o8z586 ~:
steam and water used in the emulsification step.
The combination of extraordinary dispersal of atomization of the hydrocarbon vapor at the burner head and vaporized water provides an extremely efficient, stable flame.
-3a--` iO82586 .
1 Of particular importance, llowever, is the ability to achieve this flame with little, if any, excess oxygen. Consequently, it is believed that any excessive formation of SO3 can be substantially avoided. Also, as those skilled in the art will realize from reading this disclosure, such a highly efficient combustion will minimize the amount of nitrogen which must be heated, will allow highly efficien~ heat exchal-tJe, primarily thL-ough radiation, and allow greatly reduced stack temperatures and, most importantly, provide a process which allows more stability and consequently a more dependable ratio of the selected stack yas temperature.
It is not known precisely why the process exhibits such extraordinary efficiency and stability. It is thought that the gasesous material, e.g. air or steam, is more efficiently,~emulsified when using the vigorous gas/water/llydrocarbon contact step and that this results in an intimately mixed feed which, upon exiting the burner head, disperses with such rapidity to such small droplets that the rate of combustion of the fuel mass being fed to the furnace is achieved with an unusual combination of rapidity and efficiency. The presence of water vapor in the zone into which this rapid combustion takes place is beleived to provide a stabilizing "brake" on the combustion rate, thereby providing a highly efficient and practical process.
.
- ~082S86 It is usually convenient to utilize excess gas from the con-ditioning tank as an atomizing fluid at the burner head.
Normal:Ly such excess gas, be it air or steam or the like, will have p:icked up some fuel in the conditioning tank.
It has been observed that the flame produced by the most efficient use of the process is a vivid greenish color; this color seems to characterize the quality of the more efficient processes operated according to the invention. However, it should be realized advantage is also achieved at temperatures below those at which the green flame is noticed.
It is desirable to preheat the heavier liquid hydro-carbon fuels. In general, it is not necessary to preheat No. 2 oil, and other such less viscous oils, under most temperature conditions. The preheating can be achieved by mix-ing with a heated fluid, such as steam used as a dispersing fluid, or by any other heating means known to the art.
It is also advantageous, in some situations, to utilize the process of the invention in a mode wherein some hydro-carbon fuel is carried into the zone around the burner head in the .p.~, i~

A pair of electrodes in a circuit including the coil of valve 69 and a source of llO-volt current. A photo cell or any other suitable means may be used to maintain a predetermined level of water in tank 45 to form a layer of water of predetermined thick-ness, or height therein, all in a known manner.
The liquid fuel supply means 75 of the invention included the oil tank 31, fuel lines 35 and 56, valves 46 and 47, liquid inlet port 55, : :
tank 45, liquid outlet port 57, fuel line 58, liquid fuel pump 37 and the burner tip 39.
