A system and method for providing continuous measurement and control of a combustion device by altering the fuel composition delivered thereto. The system includes devices for sensing related information, such as fuel characteristics, combustion characteristics, or other device characteristics, and controlling the performance of the combustion device based on the sensed information. Performance control occurs via addition of one or more additives to the fuel to adjust combustion characteristics. Via such sensing and performance control, consistent combustion device performance may be maintained, despite varying fuel characteristics. In one variation, sensing occurs for the fuel delivered to the combustion device, and one or more additives are added to the fuel, based on the composition and flow rate for the fuel. In another variation, characteristics of the combustion device in operation, such as flame characteristics, are sensed and used to adjust fuel characteristics via iterative addition of one or more additives.

A method and apparatus to simulate a flow of products from a real fire without reproducing a thermal environment associated with the real fire includes the release of a gas or a mixture of gases with an appropriate density less than air to simulate smoke movement from real fire sources. The buoyant inert gas may be helium. In some embodiments, the buoyant gas is combined with artificial smoke, such as a tracer gas or an inert dye (e. g. , a particulate) to provide a visual representation of the location and flow characteristics of the surrogate smoke that is released from a release apparatus. In another embodiment, optical techniques that show differences in gas density are used to visualize the movement of the buoyant gas. The release apparatus includes a control system that follows a prescribed time-dependent flow rate to simulate different fire source configurations and growth rates.

A gas stream with a reduced oxygen concentration relative to ambient air is used to vaporize a liquid fuel or liquefied higher hydrocarbon gas, or is mixed with a vaporized gas, and the reduced oxygen vaporized fuel gas is fed to a combustion device such as a premixed or diffusion combustor. Preferably, the oxygen content of the gas stream is less than the limiting oxygen index. By mixing the fuel with a gas stream that has an appropriately reduced oxygen content, auto-ignition prior to the desired flame location in the combustor can be avoided. In some embodiments, the reduced oxygen stream is generated from an air separator or taken from the exhaust of the combustion device.

A process is provided, which comprises transforming a synthesis gas into a liquid fuel, producing a fuel gas using the liquid fuel and a first gas, the first gas having an oxygen content less than that of ambient air, and contacting the fuel gas with a second gas, the second gas comprising at least one oxidizing agent, to form a combustion gas. Systems for carrying out the process are also provided.

In one embodiment of a method for vaporizing liquids such as fuels, the liquid is sprayed into a chamber such that the spray does not impinge on any surface. The energy for vaporization is supplied through the injection of a hot diluent such as nitrogen or oxygen depleted air. Additional heat is added through the surface. In another embodiment, the liquid is sprayed onto a hot surface using a geometry such that the entire spray is intercepted by the surface. Heat is added through the surface to maintain an internal surface temperature above the boiling point of the least volatile component of the liquid. The liquid droplets impinging on the surface are thus flash vaporized. A carrier gas may also be flowed through the vaporizer to control the dew point of the resultant vapor phase mixture.
