Abstract:
A combustion system (102) having a furnace (104) arranged and disposed to receive solid fuel and oxygen and combust the solid fuel and oxygen to form a flue gas. The system includes a heat exchanger (106) arrangement arranged and disposed to receive heat from the flue gas, where the heat exchanger arrangement has a predetermined heat exchange capacity. A water injection arrangement (108) is arranged and disposed to provide water to the flue gas to controllably adjust the flue gas mass flow rate and temperature to provide the predetermined heat exchange capacity.
Abstract:
A burner apparatus includes a fluid-based flame stabilizer for discharging a stabilized flame therefrom, a burner tile, and fuel lances associated with the burner tile. Each of the fuel lances has a discharge nozzle. A Coanda feature having an internal Coanda surface directs a portion of the stabilized flame from the passage defined by the burner tile at the discharge end of the primary flow passage toward at least one first fuel lance of the plurality of fuel lances to cross light the at least one first fuel lance. In another embodiment, a method of combustion includes supplying a first gaseous fuel to fuel lances of a burner apparatus and igniting and sustaining combustion of a gaseous fuel by cross lighting at the discharge nozzles of the fuel lances by flow from the fluid-based flame stabilizer along a Coanda surface of a Coanda feature toward the discharge nozzles.
Abstract:
A method for combusting oil from an oil-containing layer floating on water as from an oil spill or well leak. In the method, an oxygen-containing gas is passed through a conduit, the oxygen-containing gas from the conduit is introduced proximate the oil-containing layer floating on water, and oil from the oil-containing layer is combusted with the oxygen-containing gas in the presence of a flame. The oxygen-containing gas is introduced with an oxygen molar flow rate sufficient to decrease the opacity of a smoke plume from the combusting oil.
Abstract:
A method for determining temperature information for a plurality of tubes in a furnace where one or more digital images provide temperature information for imaged tubes, and temperature information for non-imaged tubes is determined from the temperature information for the imaged tubes and measured temperatures of combined effluent from the imaged and non-imaged tubes.
Abstract:
System and process for producing a H 2 -containing product gas and purified water from an integrated H 2 -producing reforming and thermal water purification process. Raw water, such as salt water, is heated by indirect heat transfer with reformate from the H 2 -producing reforming process for purifying raw water in a multiple effect distillation process.
Abstract:
Process for producing a hydrogen-containing product and one or more liquid water products using catalytic steam-hydrocarbon reforming. In the process, a portion of the make-up water is heated by the reformate and another portion of the make-up water is heated by the combustion product gas prior to introducing the make-up water to a deaerator. Water in the combustion product gas is condensed to form a liquid water product. The process may be integrated with a thermal water desalination process.
