  • Patent number: 10830432
    Abstract: To heat a furnace chamber (16) indirectly using radiant tubes (11) to (14), heating energy is transferred through the radiant tube wall into the furnace chamber (16). During steady-state operation, the temperature in the radiant tube (11) to (14) and on its surface is higher than the furnace, depending on the specific heat output of the radiant tube (11) to (14). At a furnace temperature of 770° C. and a heat output of 50 kW/m2, the radiant tube has a temperature of 900° C. The radiant tube (11) to (14) can thus operate continuously with flameless oxidation at this output, even though the temperature in the furnace is only 100° C. However, if the radiant tube (11) to (14) has cooled to the furnace temperature of 770° C. during a break in burning, deflagration is avoided when the associated burner is ignited by initially operating said burner with a flame for a few seconds.

    Abstract: A grid of pipes for conducting steam at a pressure greater than a vessels' operating pressure and delivering the steam throughout the grid forms the internals for a tailings solvent recovery unit. The delivery of steam throughout the grid aids in maintaining a relatively low partial pressure throughout the vessel to act as a driver for mass transfer. Conducting the steam at the higher pressure through the pipes in the grid permits a surface of the pipes to be heated to a temperature higher than possible in a conventional vessel, increasing the heat transfer to the feed stream which flows through the grid.

  • Patent number: 7533633
    Abstract: The invention relates to the establishing of a connection between steam generator heating surfaces made of austenitic materials and a collector and/or distributor made of martensitic or ferritic materials or of a nickel-base alloy. In order to extend the expectation of serviceable life of the connection, the pipe nipple of the reservoir used as a collector or distributor is made of a nickel-base alloy and directly welded to the collector wall in such a manner that an axial gap remains between the connecting branch and the collector wall. In a connection of the aforementioned type between steam generator heating surfaces made of austenitic materials and the pipe nipple or the pipe nipple and the collector made of martensitic materials, the coefficient of expansion of the material of the pipe nipple has a particularly good effect upon the serviceable life of the entire connection.

  • Patent number: 7509927
    Abstract: A hydraulic header for a heating system includes a header housing having a vertical longitudinal axis in an installation position and a water chamber formed in an interior of the housing. A boiler inlet flow connection and a boiler return flow connection are provided at a vertical distance to one another on a first longitudinal side of the housing, and each communicate with the chamber. A consumer inlet flow connection and a consumer return flow connection are provided at a vertical distance to one another on an opposite longitudinal side of the housing, each communicating with the chamber, so that a boiler side and a heating circuit side are created in the housing. A dividing element is located in the chamber between the heating circuit side and the boiler side, and an upper and lower bypass between the heating circuit side and the boiler side are formed near a top end and a bottom end, respectively, of the housing.

  • Patent number: 7487745
    Abstract: The tube assembly device of the present invention maintains spacing for proper heat transfer and avoids tubing wall removal should weld failure occur, thereby decreasing leakage of boiler tubes, shut down time and unscheduled down time for inspections and repairs. Productivity of the boilers is increased and maintenance costs are decreased. In the event of excess stress on the positioning assembly, the retainer assembly of the present invention allows for failure points to occur on the boiler tube position retainer assemblies rather than on the boiler tubes themselves.

  • Publication number: 20090007792
    Abstract: A hot beverage brewing apparatus. A pressurized hot liquid delivery system provides liquid under pressure within a range of acceptable brewing temperatures without any mechanical pump. Water is apportioned into sealable tank volumes, one of which is heated to boil the liquid and produce steam under pressure. The pressurized steam displaces the liquid from the tank volumes in proportion and at a temperature that is within the acceptable brewing range. The hot liquid under pressure is directed to a capsule receiving station to infuse a material in a capsule. The capsule dispenses the brewed beverage without contacting the brewing apparatus.

  • Patent number: 7464671
    Abstract: A structural framework for supporting the heat exchanger of a steam generator, the former being comprised of serpentine tubes having sloped segments to facilitate the drainage of water from the heat exchanger when the steam generator is shutdown. The structural framework includes paired groups of vertically and diagonally extending first support members contiguously straddling the sloped-tube segments. The paired first support members are rigidly connected by second support members which extend between adjacent sloped-tube segments. The structural framework preserves the spacing between the sloped-tube segments and prevents direct contact between adjoining tube surfaces, but is not attached to the straddled tube segments and, thus, provides a tube supporting fit that is loose enough to permit the tubes to move freely due to expansion and contraction at different rates from that of the structural framework.

  • Patent number: 7204061
    Abstract: A fireproof structure protects water pipes with stable durability even in a high temperature gas environment. Even in a case where it falls off, it does not leave the water pipes suddenly exposed. The fireproof structure for protecting water pipes 25B installed on water pipe walls of a combustion gas side is configured by a double-layered structure made up of an outer layer water pipe protective structure facing towards the combustion gas side, which is fireproof tile 13, and an inner layer water pipe protective structure provided between the outer layer water pipe protective structure and the water pipes, which is fireproof castable 12. The thickness ratio between the castable 12 and the tiles 13 lies within the range of about 2:1 to 3:1, and the ratio between the thickness of the fireproof castable and the radius of the water pipe is set to 1+?:1, wherein the value of ? ranges from approximately 0.1 to 0.3. The water pipes are equipped with hanging hooks 15a for tiles 13.
