Abstract: A heat exchanger comprising an outer jacket (9) with an inner set of vertical pipe elements (1) fastened at their opposing ends in upper and lower sieve walls (2, 3), and having a gas combustion chamber (4) located above the upper sieve wall, as well as partitions (5, 6, 7) mounted crosswise of the pipe elements. The partitions have openings for the pipe elements. The heat exchanger is also provided with liquid, gas and exhaust fumes inlet and outlet stub pipes. The outer jacket is conically shape with its diameter increasing upwards. An upper sieve wall (2), is essentially flat as viewed from the side, while an upper partition (5) situated below the wall, is shaped as a cone with its vertex pointing down. The upper partition (5) has a central opening (8) in its central region and an outer diameter corresponding to a diameter of the outer jacket (9).

Abstract: A self-sustaining boiler system for generating usable energy and heat without creating pollution. The self-sustaining boiler system includes a boiler capable of generating efficient usable energy and heat, and also includes an exhaust purifying assembly being in fluid communication to the boiler for removing the pollutants from the exhaust generated by the boiler, and further includes a fuel source assembly being in fluid communication to the boiler for providing fuel to the boiler.

Abstract: A furnace tube arrangement for a steam generator is described. A plurality of furnace tubes disposed longitudinally form a generally planar wall structure into which burner throats are let at least two longitudinally spaced levels in familiar manner. Burner throats at the respective levels are so disposed that a vertical mid-line of each throat at a first level is laterally offset from a vertical mid line of a corresponding throat at a second level.

Abstract: A furnace of a boiler for a power plant includes an outer water tube section adapted to receive water from the outside and heat the water into hot water (including steam); and an inner water tube section adapted to receive water from the outside and heat the water into hot water (including steam) while allowing the water to be moved upwardly. The outer water tube section is formed in a shape gradually increasing or substantially uniform in diameter from the bottom toward the middle portion M, and gradually decreasing, increasing and decreasing again in diameter from the middle portion M toward the top, and the inner water tube section is formed in a shape gradually decreasing and increasing in diameter from the bottom toward the middle portion M, and gradually decreasing, increasing and decreasing again in diameter from the middle portion M toward the top.

Abstract: A method for supplementing fresh water into a boiler, which can effectively exhaust air from a pipeline circuit connected with the boiler, is disclosed. The method includes the steps of: a) determining whether a supply of the supplementary water into the boiler is completed; b) operating a circulation pump with a first operation manner for a first predetermined period when the supplementation of the fresh water is completed; and c) operating the circulation pump with a second operation manner for a second predetermined period after the first predetermined period passes. Therefore, the air, which has flowed into the pipeline circuit when the supplementary water was supplemented into the boiler, is effectively exhausted.

Abstract: A hot water heater including a housing, a plurality of heat exchanging devices connected in series and disposed inside the housing at different elevations, a heat source disposed inside the housing at the bottom and controlled to heat water in the heat exchanging devices, a cold water pipe connected to the heat exchanging device at the topmost elevation to guide cold water through the heat exchanging devices, a hot water pipe connected to the heat exchanging device at the lowest elevation to guide hot water out of the heat exchanging devices, the heat exchanging devices having vertical air ducts for guiding hot air through the heat exchanging devices, the air ducts of one heat exchanging device at a higher elevation being not vertically in alignment with that of a next heat exchanging device at a lower elevation.

Abstract: A combustion device for producing predetermined radiation spectral output and heat for a variety of applications including lighting, cooking, heating water, electric power generation, and providing inexpensive photons to enhance chemical and physical reactions.A process for the preparation of a porous ceramic burner is described which comprises drawing a solution which contains metal oxide fibers onto a burner skeleton by use of a vacuum to form a base fiber layer. The base fiber layer is dried, after which an additional metal oxide fiber layer, the outer fiber layer, is added over the base fiber layer. In another embodiment of the invention, an intermediate fiber layer is placed over the base layer, prior to the addition of the outer fiber layer.

Abstract: A heat exchanger adapted to handle dusty hot waste gases including a vertically oriented shell through which the waste gases flow longitudinally downward. The shell contains a tube assembly of vertical tubes having external, longitudinal heat transfer fins with the tubes being connected for fluid flow and support of their upper and lower ends to a central vertical support/header assembly. This support/header assembly is a tube divided into an upper header, a lower header and a center support tube section.
