Definitions

  • This invention lies in the field of liquid and gaseous fuels and fuel burners. More particularly, it concerns the method of preparation or modification of liquid fuels so that they can be vaporized and burned in a normal gaseous fuel burner.
  • the liquid fuel can be, for example, something like house heating oil or distillate which can be directly mixed with the water or can be emulsified, so as to maintain a constant ratio mixture.
  • the heating can be accomplished in a fuel-fired furnace, or in a heat transfer apparatus, utilizing waste heat from any available source for the supply of heat for liquid vaporization.
  • FIGURE 1 there is indicated by the numeral 10 one embodiment of the invention.
  • a stream of water indicated by the arrow 16 and a stream of liquid fuel indicated by the arrow 14, flow into a mixer 12, which may be of conventional design.
  • the outlet of the mixer flows into an emulsifier 18 to provide an emulsion of the liquid fuel and water, which flows by pipe 22 into a heater unit indicated generally by the numeral 24.
  • This can be of conventional design.
  • Illustrated in FIGURE 1 is a fuel-fired furnace 26, which is shown schematically, supplied with fuel 30 through a burner opening 28 and supplied combustion air 32, to provide a high temperature environment inside the furnace 26,to heat the internal piping 36, through which the emulsion of liquid fuel and water flows.
  • the hot products of combustion flow in accordance with arrow 34 up the stack 35 in a conventional manner.
  • the outlet pipe 38 now contains a flow of vaporized liquid fuel and steam, which goes through an appropriate valve 40, and to a gas fuel line 42 to the burner. At the junction 41 another pipe joins the line 42 and supplies a gaseous fuel 44 through a valve 46. By controlling valves 40 and 46 either one or the other source of gaseous fuel can be provided to the burners.
  • the partial pressure of fuel vapor to water vapor can be changed and, thus, the temperature and the heat content of the gaseous fuel can be made any desired value.
  • liquid vapor and steam in line 38 is operatively similar to that of the conventional gaseous fuel 44, so that no mechanical changes are required in the burner to substitute one fuel for the other.
  • FIGURE 2 is shown a modification of the system 10 of FIGURE 1, wherein the liquid fuel 14 and water 16 are simply mixed in the mixer 12, to form a mixture of droplets of oil and water to flow by line 50 to the heater 52.
  • the heater is shown as a heat transfer device, rather than a furnace as in FIGURE 1.
  • This heat transfer device can utilize waste heat from hot byproducts of other process operations, that may be available.
  • This is shown schematically as a heat transfer device with hot fluid entering at the top through line 54 and passing down in counterflow through the mixture of liquid fuel and water, which is flowing up through pipes in the interior of the heater. The cooled hot fluid leaves through line 56.
  • the heated gaseous fuel now at a high enough temperature to vaporize both the liquid fuel and the water, leaves by line 38 to go to the burner as in FIGURE 1.
  • liquid fuel and water can be mixed in various ways. They can be simply mixed, or they can be emulsified to form droplets of one liquid in the other.
  • the liquid fuel can be atomized and then mixed, or emulsified with the water, etc.
  • the heating can be carried out in any suitable manner so as to provide the proper temperature and pressure, and so as to most efficiently utilize heat that is available.
  • the vaporization occurs at a selected, and suitable pressure and vaporization temperature, which is suited to the vaporization pressure, in order to maintain both oil and water in vapor-phase at delivery to burners. Partial-pressures of oil vapor and water vapor determine required temperature, as is well-known to those versed in the art.
  • An exemplary condition might be the creation of 910 btu/cu ft substitute gas at 15# gauge pressure (29.7# Absolute Pressure) using a prior mixture of typical #2 oil (house heating oil) and liquid water at a final vaporization/superheat temperature of 400F (204.4C).
  • the calorific value at 910 btu/cu ft is based on the Lower Heating Value of the fuel.
  • the data, per million btu for gas fuel produced per hour are as follows:
  • FIGURE 2 is the preferable form of our invention because no fuel firing is required, and the use of some already heated process fluid as a heat-medium conserves fuel through avoiding direct-firing for vaporization.
  • the heat-medium fluid can be any which is available at suitable temperature level for oil-water vaporization at required pressure, which is typically the case.
  • the configuration of FIGURE 1 is next in the order of decreasing preferability due to required fuel usage.
  • the simple mixer of FIGURE 2 can be applied to either FIGURES 1 or 2, since the function of oil-water emulsification prior to vaporization is not present.
  • All embodiments shown make use of the identical phenomenon,which is pre-mixture of the liquids, oil and water, prior to vaporization and superheat, for use as substitute gaseous fuel.
  • the phase of vaporization is improved.
