Patent number: 10119771Abstract: A Non-Isotropic Structure for a Heat Exchanger (NISHEX) that forms fins from nested woven wire meshes. The wire meshes are shaped into channels that are stacked on top of each other to produce a non-isotropic fin structure having multiple fin layers. The fin structure exhibits a high heat coefficient while maintaining relatively high fin efficiency through the selection of fin lengths in proportion to the wire diameter in the mesh fins.Type: GrantFiled: January 4, 2012Date of Patent: November 6, 2018Assignee: Altex Technologies CorporationInventor: John T.

Patent number: 9797289Abstract: The invention provides systems and methods for electric power production and integrated combustion and emissions control. The invention may include an engine capable of receiving air and fuel, and producing power and an engine exhaust gas. The invention may also include a first reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of more than one, thereby generating a first product. The combustion may reduce nitrogen containing species. The invention may also include a second reaction zone receiving the engine exhaust gas from the engine configured to combust fuel and air having an equivalence ratio of less than one, thereby generating a second product. The combustion may reduce or minimize NOx. The invention may also include a mixing zone configured to receive the first product and second product, and mix and react the first and second products, thereby generating an exhaust with reduced NOx levels.Type: GrantFiled: May 15, 2015Date of Patent: October 24, 2017Assignee: ALTEX TECHNOLOGIES CORPORATIONInventors: John T. Kelly, Carlo Castaldini, Mehdi Namazian

Publication number: 20130319261Abstract: A process and apparatus for densification of material compresses the material, then heats and cools the compressed material to provide structural integrity and durability to the resultant densified product. For a lignocellulosic biomass material an inherent binder is used. The binder is activated substantially only along the periphery of the compressed material to increase throughput and reduce energy used during the densification process.Type: ApplicationFiled: June 1, 2012Publication date: December 5, 2013Applicant: Altex Technologies CorporationInventors: John T.

Patent number: 6485289Abstract: A NOx reduction burner system and process. Fuel modification and fuel rich reactor zone gases are brought together with products from a fuel lean reactor zone in a low temperature burnout and NOx reduction reactor zone. The fuel modification fuel rich reactor stabilizes combustion through recirculation of hot gases to the reactants. Nitrogenous species decay reactions in the fuel rich zone controls the production of NOx. The nitrogenous species from the fuel rich zone and the NOx from the fuel lean zone then react in the burnout zone at an optimal temperature and nitrogenous species mix where NOx is minimized. Temperature in all zones, and in particular the burnout zone, can be controlled by furnace gas entrainment, induced flue gas recirculation, forced flue gas recirculation and active cooling by radiative and/or convective heat transfer. NOx can be even further reduced by introducing ammonia, or a like amine species, into the low temperature burnout zone.Type: GrantFiled: January 8, 2001Date of Patent: November 26, 2002Assignee: Altex Technologies CorporationInventors: John T.

Patent number: 6000930Abstract: A low NOx combustion process and burner apparatus in which a mixture of a primary fuel and air, with the air in excess of the stoichiometric requirement, is passed to a surface burner element. The mixture is distributed over the downstream side of the element where it is combusted in a primary combustion zone. Secondary fuel is mixed with surface combustion products from the primary zone and then combusted in a secondary combustion zone with a portion of excess oxygen from the surface combustion products. In certain embodiments the temperature of surface combustion products is reduced by heat transfer to the surface burner element, and in another embodiment by heat transfer to a screen or other element placed within the primary combustion zone, from which the heat is then extracted to a load, and in another embodiment by mixing the additional fuel or combustion products with cooled furnace gases. In other embodiments the placement of the secondary fuel jets is varied to achieve different combustion results.Type: GrantFiled: May 12, 1997Date of Patent: December 14, 1999Assignee: Altex Technologies CorporationInventors: John T.
