Patent number: 5299534Abstract: A single-drum recovery boiler comprising a superheater (2), boiler bank elements (3a) forming a boiler bank, and elements (3b) forming an economizer. In the recovery boiler, a plurality of boiler bank elements (3a) and economizer elements (3b) are disposed alternately so that a boiler bank--economizer unit (3) is achieved where the ratio between the boiler bank elements and the economizer elements is optimized in relation to the operating conditions of the boiler.Type: GrantFiled: January 21, 1993Date of Patent: April 5, 1994Assignee: Tampella Power Oy of LipintieInventor: Pentti Janka

Patent number: 5299535Abstract: A vapor generation apparatus which includes a furnace, having a tube wall and at least one vertical buckstay member disposed proximate to the outer face of the spiral tube wall. The apparatus includes a stirrup for transmitting forces between the spiral tube wall and the vertical buckstay member. The stirrup includes a U-shaped plate and a cylindrical member, apparatus for mounting the cylindrical member on the vertical buckstay member including first and second lugs fixed to the vertical buckstay member in spaced relationship. The cylindrical member is fixed between the first and second lugs in spaced relation to the vertical buckstay member. The apparatus also includes apparatus for mounting the U-shaped plate on the tube wall.Type: GrantFiled: December 29, 1992Date of Patent: April 5, 1994Assignee: Combustion Engineering, Inc.Inventor: Ronald G. Payne

Patent number: 5299536Abstract: Apparatus is disclosed herein for reducing engine nitrogen oxide emissions by mixing hydrogen prepared from a portion of engine fuel within a simple burner. The apparatus includes a burner having an internal combustion chamber for receiving either a portion of gaseous fuel or liquid fuel for mixture with air and subsequent ignition by a spark plug. A mixing chamber is included having a series of baffles against which injected air and fuel vapor impinge causing thorough and complete air/fuel blending into a mixture subsequently ignited and burned, and then discharged into the combustion chamber of the engine itself. A preheating arrangement is provided for raising the temperature of the air/fuel mixture via a heat exchanging process with the combusted gases in the combustion chamber.Type: GrantFiled: December 28, 1992Date of Patent: April 5, 1994Inventors: David Moard, Leonard Greiner

Patent number: 5299537Abstract: A metered induction two cycle engine is presented. In accordance with the metered induction two cycle engine, an aspirating cylinder (or pulsing air-charger) is connected to a combustion cylinder by a voluminous transport duct having a valve disposed therein. The valve permits flow from the aspirating cylinder and duct to the combustion cylinder and prohibits flow in the opposite direction. The duct acts as an extension of the clearance volume of the aspirating cylinder. The valve is actuated when the pressure in the duct exceeds the pressure in the combustion cylinder. Further, the aspirating cylinder leads the combustion cylinder by a fixed amount to provide a disciplined flow of mixture (i.e., air and fuel) into the combustion cylinder.Type: GrantFiled: March 11, 1992Date of Patent: April 5, 1994Inventor: Ransom S. Thompson

Patent number: 5299538Abstract: An internal combustion engine block having a circumferential channel formed between the cylinder block and a cylinder liner, surrounding and adjacent to the high temperature combustion chamber region of the engine, to which coolant flow is diverted from the main coolant stream to uniformly and effectively cool this critical area of the liner. The high velocity flow of the main coolant stream, as it passes the end of the cylinder liner adjacent the combustion chamber, provides a reduced pressure head at the port interconnecting the outlet end of the circumferential channel with the main coolant stream. Channel entrance holes, located upstream at relatively stagnant regions in the main coolant flow, are at a higher pressure head than the channel exit port, thus inducing flow through the channel at a high velocity flow.Type: GrantFiled: May 5, 1993Date of Patent: April 5, 1994Assignee: Detroit Diesel CorporationInventor: Lawrence C. Kennedy

Patent number: 5299539Abstract: In an engine speed controlling method in a PI isochronous control mode, the initial value of an integral term for PI control is determined when the difference between a given target engine speed and an actual engine speed becomes more than a prescribed level, and the value of the integral term is change to the value of a no-load rack position at which the target engine speed is maintained in no engine load condition, when the actual engine speed becomes equal to the target engine speed, whereby large overshoot and undershoot can be effectively suppressed.Type: GrantFiled: March 18, 1993Date of Patent: April 5, 1994Assignee: Zexel CorporationInventor: Kazumasa Kurihara

Patent number: 5299540Abstract: A respective fuel injector is provided for each cylinder in a multiple cylinder internal combustion engine. Each fuel injector is located in a respective cylinder head. There are a plurality of fuel passages for each cylinder head. Each fuel passage into the cylinder head is in two sections. One section extends from the space for receiving the fuel injector diagonally with respect to the longitudinal direction of the engine and opens on the transverse surface of the cylinder head and is sealed there. Another passage section extends at an angle to the first passage section and then intersects the lateral side surface of the cylinder head. The two passage sections each comprise a bore in the cylinder head. A wall inside the cylinder head extends between and separates two spaces for receiving inlet valves to the injector and two spaces for receiving exhaust valves from the injector. That wall extends on one side along an air intake port into the cylinder head.Type: GrantFiled: February 22, 1993Date of Patent: April 5, 1994Assignee: Saab Scania AktiebolagInventors: Hakan Fransson, Peter Sperle

Patent number: 5299541Abstract: A high-pressure fuel injection tube for a diesel engine, comprising: a tube body having connecting heads at its two end portions; fastening nuts assembled at the backs of the connecting heads; a pair of separate outer tubes so fitted on the outer circumference of the tube body as to be spaced from each other at a gap between the opposed end faces thereof and to move in the axial direction; seal ring members so fitted on the outer circumferences of the outer tubes in the vicinity of the outer end portions of the outer tubes as to engage with the fastening nuts respectively; and a relatively short joint cylinder fitted on the outer circumferences of the outer tubes across the inner end portions of the outer tubes. Further comprised is a seal ring member which is fitted between at least one fitted end portion of the joint cylinder and the outer circumference of the faced one of the outer tubes.Type: GrantFiled: April 16, 1993Date of Patent: April 5, 1994Assignee: Usui Kokusai Sangyo Kaisha Ltd.Inventors: Isao Yamaguchi, Yasushi Sakamoto
