摘要： A method and apparatus for combustion of a fuel in which a first-stage fuel and a first-stage oxidant are introduced into a combustion chamber and ignited, forming a primary combustion zone. At least about 5% of the total heat output produced by combustion of the first-stage fuel and the first-stage oxidant is removed from the primary combustion zone, forming cooled first-stage combustion products. A portion of the cooled first-stage combustion products from a downstream region of the primary combustion zone is recirculated to an upstream region of primary combustion zone. A second-stage fuel is introduced into the combustion chamber downstream of the primary combustion zone and ignited, forming a secondary combustion zone. At least about 5% of the heat from the secondary combustion zone is removed. In accordance with one embodiment, a third-stage oxidant is introduced into the combustion chamber downstream of the secondary combustion zone, forming a tertiary combustion zone.

摘要： A multi-stage heating apparatus having a first stage combustion chamber, a second stage combustion chamber, a primary porous matrix chamber disposed between the first and second stage combustion chambers, a secondary porous matrix chamber, heat exchanger tubes for transfer of heat from the combustion products to a working fluid, a recirculation device for recirculating combustion products in the first and second stage combustion chambers to the root of flames therein. A mixture of fuel and primary oxidant is introduced into the first stage combustion chamber, and the products of combustion therein are conveyed to the porous matrix chamber disposed between the first and second stage combustion chambers. After undergoing intensive heat transfer in the porous matrix chamber, the cooler products of combustion flow into the second stage combustion chamber forming additional products of combustion. The products of combustion then flow to a second porous matrix chamber in which they undergo further intensive heat transfer. From there, the products of combustion pass through an economizer for preheating a working fluid and through a condenser for removing moisture in the combustion products prior to being exhausted.

摘要： A heating system having a steam generator or water heater, at least one economizer, at least one condenser and at least one oxidant heater arranged in a manner so as to reduce the temperature and humidity of the exhaust gas (flue gas) stream and recover a major portion of the associated sensible and latent heat. The recovered heat is returned to the steam generator or water heater so as to increase the quantity of steam generated or water heated per quantity of fuel consumed. In addition, a portion of the water vapor produced by combustion of fuel is reclaimed for use as feed water, thereby reducing the make-up water requirement for the system.

摘要： A method for removing a condensable component from a process stream in which a first side of a permselective membrane is contacted with the process stream in which is disposed the condensable component. The condensable component is passed through the permselective membrane to a second side of the permselective membrane, forming a condensable permeate. The condensable permeate is then contacted with a liquid stream having a liquid form of the condensable permeate, forming a condensed permeate. The condensed permeate may then be returned to the process which generated the process stream.

摘要： A combustion system having at least one wall enclosing a combustion chamber and forming a plurality of burner or burner nozzle openings. Disposed within each of the openings is a premix burner or burner nozzle, each of which has a premixed fuel/oxidant outlet proximate the combustion chamber and a fuel/oxidant inlet distal from the combustion chamber. At least a portion of the premix burners or burner nozzles are sized to produce different fuel/oxidant delivery disturbance response times in response to a pressure disturbance within the combustion system. Differences in fuel/oxidant delivery response times are achieved by using burners or burner nozzles having different internal dimensions, different volume flow rates, and, optionally, by varying the fuel/oxidant ratios of the mixtures flowing through the burners or burner nozzles.
