  • Patent number: 8997666
    Abstract: A combustion device in the form of an elevated fixed-grate that includes arcuately shaped solid refractory brick with ribs placed thereunder so as to allow horizontal air flow for fuel combustion. The brick are arranged atop one another in a stacked concentric configuration that forms a central fuel passageway and allows cascading of a fuel pile throughout the combustion stages. The device provides the benefit of proper de-ashing online while distributing the underfire air radially around the fuel pile. The elevated design of the bricks allows the air to be evenly distributed throughout the fuel pile and further allows the isolation of overfire and underfire air. Segregating overfire and underfire air in an evenly distributed manner allows the burner to combust a wide range of fuel moisture contents without modifying the mechanical components of the burner.

  • Publication number: 20140208997
    Abstract: The invention relates to designs for the linings and roofs of heat-engineering units for mechanical engineering and can be used in the construction of industrial furnaces in the metallurgical, heat-engineering, petroleum-processing and petrochemical industries, in the production of construction materials and in other branches of industry. The aim of the invention is to produce a strong refractory lining for resistance furnaces with a low consumption of electrical energy and a reduction in the weight and overall dimensions of the furnace. All parts of the furnace lining are formed using monolithic blocks made of high-strength refractory, electrically nonconductive phosphate concretes and are used as load-bearing construction elements. Said elements are used in resistance furnaces with an operating temperature of up to 1000° C.

  • Patent number: 8679447
    Abstract: SO3 is formed from a replenished circulating inventory of fresh and recycled SO2. Also, a feed stream of replenished SO2 is heated by indirect heat exchange with a hot stream of SO2 and SO3 whereby the hot stream is cooled for separating the two gases. The heated feed stream of replenished SO2 serves as a hot gaseous feed to a sulfur burner. This SO2 feed is divided into two feed streams, one being oxygenated with pure oxygen and the other remains as an SO2 feed. These feeds plus a feed of molten sulfur are concurrently and separately introduced into the sulfur burner where additional SO2 is formed via continuous exothermic reaction. Although heated, the oxygenated feed(s) of SO2 bring in the needed oxygen for the reaction and the feeds of the oxygenated and non-oxygenated SO2 serve as a heat sink in the sulfur burner to reduce the temperature therein.

  • Patent number: 8446929
    Abstract: A brick hearth system includes a rigid containment shell in which a concave bottom is lined with a hearth refractory sub-layer and hearth brick working layer. The outer perimeter of the hearth refractory is ringed with thrust blocks to compress the whole toward the center and to thereby deny gaps from forming between the separate bricks. Many individual thrust rods penetrate the outer bottom of the containment shell, and such are used to transmit compression forces generated outside the shell to be applied against the thrust blocks in unison. Each thrust rod receives an adjustable amount of inward force from a spring, acting either directly or through a beam or rocker arm. These are anchored to and use the hoop strength of the containment shell as leverage. As the hearth brick working layer grows during its service life, the ring of thrust blocks grows in diameter as well inside the margins provided within the containment shell.

  • Patent number: 6393789
    Abstract: A refractory anchor and method of use. The anchor is made by combining two similar sections that are clinched together to form an elongated X-shape. The bilateral symmetrical shape affords maximum anchorage of the refractory, and through-flow of the refractory is afforded by voids through the anchor. The anchor has feet that attach to the surface to be protected, thus allowing refractory to migrate under the anchor. The similar sections can also be used alone as anchors where placement area is limited or irregular. In an alternative embodiment, the anchors have only center feet, to allow them to be stud welded. The anchors are useful in both repair work as well as new refractory applications.

  • Patent number: 6244197
    Abstract: Chimney-like cooling passages that have opposite outlet and inlet end regions open to ambient air also have central regions that extend through heated components of industrial furnaces. The passages preferably are defined by conduits that are oriented and configured in a manner that enables thermally induced flows of ambient air to self establish through the conduits to cool the furnace components once the furnace components become heated. The passages function like chimneys, with each having its outlet located higher than its inlet so that ambient air will effectively rise as it flows from the inlet to the outlet. The passages may provide increases in cross-sectional area somewhere along their lengths so that heated ambient air expanding in the passages is encouraged to discharge from the less restrictive, larger area outlets rather than from the smaller area inlets.

  • Patent number: 6145452
    Abstract: An arrangement for insulating a wall of a metallic combustion chamber is disclosed. A layer of insulating material is applied to the metallic wall and a plurality of ceramic wall panels are applied over the ceramic insulation material. The wall panels are retained by fastening elements that pass through an opening in the wall panels. The opening in the wall panels has a frusto-conical surface and the engagement surface of the fastening element is at least partially spherical to avoid mechanical and thermal stresses.

  • Patent number: 6126438
    Abstract: A burner apparatus comprises a conduit adapted to convey preheated oxidant and having outlet and inlet ends, and a conduit adapted to convey preheated fuel and having outlet and inlet ends. The conduit adapted to convey preheated fuel is substantially parallel to the conduit adapted to convey preheated oxidant. The conduit adapted to convey preheated oxidant is positioned substantially vertically above the conduit adapted to convey preheated fuel. The conduit adapted to convey preheated oxidant and the conduit adapted to convey preheated fuel each are positioned within its own respective elongate cavity in a refractory burner block. Each of the conduits are positioned in their respective cavity such that a substantially annular region is present between an outer surface of each conduit and its respective cavity. Each conduit inlet end extends through a respective plenum for receiving an ambient temperature fluid, the plenums adapted to pass the ambient temperature fluid into the respective annular regions.

  • Patent number: 6024085
    Abstract: The present invention encompasses a modular fireplace having a first side wall, a second side wall, and a back wall that is contiguous with the first side wall and the second side wall and defines an interior open-faced firebox region having a substantially "U" shape in top plan view. The first side wall is constructed from a plurality of sequentially stacked modular first side blocks and the second side wall is formed from a plurality of sequentially stacked modular second side blocks. The back wall has a first modular corner block, a second modular corner block, and at least one substantially vertical spacer block that are joined so that the first corner block and the second corner block are contiguous with the spacer block. To aid in the efficient drafting of the fireplace, each of the spacer blocks may have a spacer block air chamber extending therein from an open upper end on the spacer block top end to a closed lower end proximate the spacer block bottom end.

  • Patent number: 5785517
    Abstract: A wall lining for a furnace (10) includes a refractory layer (14) having a hot face (16) exposed to the interior of the furnace. A plurality of elements of a high thermal conductivity material (18), such as copper wires or rods, extend from the outer shell (12) of the furnace into the refractory lining (14). The elements (18) provide a continuous heat conduction path to the outer shell (12) of the furnace. A cooling jacket (22) removes heat from the outer shell. The elements (18) are dispersed in the refractory lining (14) to provide a substantially uniform temperature across the hot face of the furnace in the vicinity of the elements. The wall lining may be formed by fixing an array of the elements to the inside wall of the outer shell of the furnace and applying a refractory material to the inside wall.
