摘要： An apparatus for heating a fluid in a process having a process heat requirement includes a shell, at least one tube having a design temperature inside the shell, a plurality of burners adjacent the inner wall of the shell, and transfer means whereby flue gas flows from a first interior region to a second interior region of the shell. A first portion of the tube is in the first interior region and a second portion of the tube is in the second interior region. The first and second portions of the tube are adapted to contain a flow of the fluid. The burners produce the flue gas in the first interior region and a variable heat flux approximating the process heat requirement and simultaneously maximizing the heat flux to the first portion of the tube while maintaining substantially all of the first portion of the tube at the design temperature.

摘要： A method and apparatus for introducing an oxidant mixed with a carrier gas into pre-heating zone of a continuous furnace for effectively removing lubricant from powder metal compacts prior to sintering at high temperatures. Mixing a controlled amount of a gaseous oxidizing agent such as moisture, carbon dioxide, air or mixtures thereof with a carrier gas and introducing the mixture into the preheating zone of a continuous furnace under controlled conditions accelerates removal of lubricant from powder metal compacts prior to sintering at high temperature by decomposing lubricant vapors into smaller and more volatile hydrocarbons, produces sintered components with close to soot- and residue-free surfaces and with the desired physical properties, prolongs the life of furnace components including muffles and belts, and reduces downtime, maintenance and operating costs.

摘要： A method for controlling NOx in a multi-zone re-heating furnace used for meeting process heating (or re-heating) requirements in the metals industry. Oxidant-fuel stoichiometry is altered in different zones of a multi-zone re-heating furnace to reduce the overall NOx emission without replacing existing burners or intrusively modifying the furnace (or drilling holes in the furnace) for fuel and/or an oxidant injection. The oxidant-fuel stoichiometry in at least one zone of a multi-zone re-heating furnace is made either oxidant neutral or oxidant deficient (or fuel rich) to reduce the formation of NOx and the oxidant-fuel stoichiometry of at least one other zone that is located downstream of the oxidant neutral or oxidant deficient zone is made oxidant rich (or fuel lean) to further reduce the formation of NOx in the furnace.

摘要： A furnace combustion system includes a plurality of burners adapted to generate a plurality of flames and an oxidant port disposed between and surrounded by at least two of the burners. Each burner is spaced apart from another burner and adapted to combust a stream of a first fuel or an other fuel with a stream of a first oxidant or an other oxidant and to generate a flame. The oxidant port is adapted to transmit at least one jet of the first oxidant or the other oxidant axially between at least two of the flames. The at least one jet is transmitted from the oxidant port at a controlled flow rate. At least a portion of the first oxidant or the other oxidant in the jet is required to complete combustion of at least a portion of at least one stream of the first fuel or the other fuel.
