20090050076 - Boiler producing steam from flue gases with high electrical efficiency and improved slag quality: This invention relates to a boiler (1) drying, igniting and combusting refuse and producing steam (2, 2a) by heat exchange with flue gases (3). Said boiler (1) comprises a reactor (16) with firing a secondary fuel (18) for generating a less-corrosive gas flow (6) and an end superheater (8) located... Agent: Stites & Harbison PLLC

20090050079 - Economizer for a steam generator: An economizer for a heat recovery steam generator utilized to improve the efficiency of the Rankine cycle by preheating the water that flows to the evaporator section. The economizer multi-pass sections include up-flow tubes only. This arrangement greatly reduces thermal stresses on the tubes by ensuring that each individual tube... Agent: Litman Law Offices, Ltd.

20090050077 - Mutually convertible boiler between normal type and condensing type: Disclosed is a boiler which is easily convertible from a normal type oil boiler to a condensing type oil boiler or vice versa thereby reducing manufacturing costs for the boiler. A size and a weight of the boiler are reduced by vertically installing a latent heat exchanger in an outer... Agent: Greer, Burns & Crain

20090050078 - Flanged boiler tube: A boiler apparatus comprises a supply manifold which includes a first flange having a first aperture defined therein. A boiler tube, including a second flange having an aperture defined therein, is secured to the manifold. A releasable fastener maintains sealed engagement of the first flange with the second flange.... Agent: Pitts And Brittian P C

20090044766 - Method for disassembling a boiler: A method for disassembling a boiler supported on a supporting structure is disclosed. The method includes a holder installation step for providing a vertically extendable ascent-descent holder below the boiler; a holder lifting step for increasing a height of the ascent-descent holder to a position close to or in contact... Agent: Birch Stewart Kolasch & Birch

20090044767 - Boiler arrangement: In a boiler, a space is reserved to expand the boiler by increasing the front and rear walls. To expand the boiler, wall additions are added to increase the width of the front and rear walls. After the expansion, the distance between the front and rear walls is substantially the... Agent: Nixon & Vanderhye, PC

20090044765 - Device with fluid distributor and measured value recording and method for operation of a boiler with a throughflow of flue gas: Certain techniques involve the use of a device including a fluid distributor which has at least one flow duct with an inlet opening and an outlet opening. The inlet opening can be connected to a supply line for a fluid. Means for moving the fluid distributor are provided. Additionally, means... Agent: Bainwood Huang & Associates LLC

20090031967 - Integral waterwall external heat exchangers: A combustion system having a combustor that includes tubing for carrying boiler water, a cyclone to recover solids from exhaust of the combustor and an external heat exchanger to recover heat from the solids, includes: a bypass for providing boiler water from the combustor to tube bundles of the external...
