Patent number: 8764869Abstract: The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. A centrifugal separator is provided as comprising a housing defining an inner space, and a rotor assembly for imparting a rotary motion onto a mixture of substances to be separated. The rotor assembly is located in said inner space and is rotatable about an axis relative to the housing. The rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet.Type: GrantFiled: January 10, 2012Date of Patent: July 1, 2014Assignee: Alfa Laval Corporate ABInventor: Thomas Eliasson

Patent number: 7272934Abstract: A novel process and apparatus for power generation from biomass and other carbonaceous feedstocks are provided. The process integrates a pulse combustor steam reformer with a gas turbine to generate electricity such that (i) efficiency is higher than those of conventional and current advanced power systems, (ii) emissions are lower than those proposed in the new environmental regulations, and (iii) performance is comparable to that of combined cycle, even though a bottoming cycle is not included here. The pulse combustor steam reformer generates a hydrogen-rich, medium-Btu fuel gas that is fired in a gas turbine to generate electricity. The apparatus may be configured to produce only power or combined heat and power.Type: GrantFiled: July 26, 2005Date of Patent: September 25, 2007Assignee: Manufacturing and Technology Conversion International, Inc.Inventors: Ravi Chandran, Momtaz N.
