5569312 Method for reducing NOx emissions from a regenerative glass
PatentsALERT
Vlll
flat surface arranged near the intersection of the orthogonal members. The flat section is in registry with a heat source. Movement of the flat section relative to the heat source effectuates abutment and thermal contact therebetween. The present thermal energy transfer system is designed for enhanced heat transfer within a portable computer system without undergoing the disadvantages of bulky finned heatsinks and/or fans.
5568834 HIGH T E M P E R A T U R E HEAT EXCHANGER Korenberg Jacob York, PA, UNITED STATES assigned to Donlee Technologies Inc The heat exchanger includes a hot fluid passage for guiding hot fluid through the heat exchanger, a compartment for containing a fluidized bed, a series of nozzles for forcing particulates from the fluidized bed into the hot fluid, a heat transfer device in contact with the fluidized bed, means for separating particulates from the fluid that has passed through the hot fluid passage, and a return passage for returning separated particulates to the fluidized bed in the compartment. The fluid is guided over the upper surface of the fluidized bed. Air is blown through the series of nozzles to force particulates from the fluidized bed into the fluid in the hot fluid passage where they pick up heat from the fluid, and the particulates then fall back into the bed and Wansfer heat to the fluidized bed. The heat transfer device removes heat from the fluidized bed and transfers it to a working fluid without being in contact with the hot fluid passage.
5569312 METHOD FOR REDUCING NOX EMISSIONS F R O M A R E G E N E R A T I V E GLASS FURNACE Quirk Richard; Bird David A; Shulver Ian N; Mclntosh Robin Aughton, UNITED KINGDOM assigned to Pilkington Glass Limited A method of operating a crnss-fired regenerative glass furnace for melting flat glass so as to minimize emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting the combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and permissible levels of NOx. Alternatively, the furnace may be operated at substantially stoichiometric conditions and fuel is supplied to the waste gases as they leave the melting chamber. The invention also relates to a cross-fh'ed regenerator glass furnace for use in the method. The invention further provides a method of reducing the emissions of CO in waste gases leaving a cross-fa'ed regenerative glass furnace for melting flat glass, the furnace having sealed regenerators which act as heat exchangers, the method comprising removing CO from the waste gases in the regenerator by combusting CO in around 8% excess air, based on the combustion air for the supplied fuel, at a temperature greater than 650 degrees C.
