Patent ES-370150-A1 (ES)
Title: Apparatus for condensing sealing fluid from gland structures
IPC: F01D5/32
Filed: 1969-08-01
Abstract: In a vapour, e.g. steam, turbine plant having sealing glands 34 to 39 where the rotor shaft 4 passes through the end walls of the respective turbine cylinders 1, 2, 3, the glands are supplied with sealing vapour, e.g. steam, which after leaving the glands through lines 54 to 59 is condensed in direct contact condensers 51, 52, 53. Condensation in the latter is effected by water sprayed through nozzles 61, 62, 63, the water being condensate pumped to the nozzles from the main condensers 24, 25 by pumps 28, 29. Vacuum in the condensers 51, 52, 53 is produced by electrically driven air pumps 75, 76, 77 which are interconnected by lines 78, 79 so that vacuum can be maintained in the event of a pump failure. Condensate from the condensers 51, 52, 53 is led back to the wells 26, 27 of the main condensers 24, 25 through lines 71 to 74.

IPC: F23C7/00
Filed: 1969-11-20
Abstract: A swirl-type muffle burner comprises a burner lance 4 for supplying liquid or gaseous fuel surrounded by at least two concentric annular supply ducts 40, 50 each including swirl means 11, 12 and an adjacent refractory muffle 18, the construction being such that the velocity of the air leaving the innermost duct is greater than the velocity leaving the outermost duct. The two annular ducts 40, 50 may be separated by tabular member 9 which is biased at its inlet end. The rate of flow through the outermost duct 40 may be varied by changing its inlet cross-section by adjusting a sleeve 15. The crosssectional areas of the duct exits are preferably equal, the outer diameter of the outermost duct is between 0À3 and 0À6 times the internal diameter of the muffle and the length of the muffle between 0À5 and 2À0 times the internal diameter of the muffle. The swirl means 11, 12 are arranged to give the same direction of twist to the air emerging from each duct.

Title: Coke oven battery having twin heating flues
IPC: C10B21/02
Filed: 1975-06-03
Abstract: Regenerative heating of a coke oven battery includes the combustion of lean gas and air in heating chambers disposed between the coking chambers or, alternatively, if desired, the combustion of rich gas and air in the heating chambers. Each heating chamber includes a plurality of header walls forming upgoing and downgoing heating flues. Each header wall includes at least one internal duct in open communication with a plurality of vertically-spaced exit ports at the common side of a header wall. The internal ducts receive either preheated air or preheated lean gas for combustion in a heating flue. The cross-sectional size of the exit ports to discharge air in a given heating flue increases upwardly from port to port along the header wall whereby the amount of air supplied at the sole and lower part of the heating flue is insufficient for complete combustion of the amount of lean gas supplied thereto. The cross-sectional sizes of the plurality of exit ports for lean gas in the same heating flue decrease upwardly from port-to-port along the header wall such that the amounts of air and lean gas supplied to the heating flue are sufficient for complete combustion of the smoke gas discharged from the heating flue. In one embodiment, each header wall includes two internal ducts with the discharge ports thereof in open communication with different heating flues. In a further embodiment, each header wall includes a single internal duct having exit ports at opposite sides. Combustion takes place in all the heating flues which are upgoing and located at one side of the oven chamber. A top duct interconnects all the upgoing flues with downgoing heating flues located at the other side of the oven chamber during a regenerative half-cycle.

Patent ES-470276-A1 (ES)
Title: Wood preservation
IPC: B27K3/52
Filed: 1978-05-29
Abstract: In this method, treating substances are conveyed in water, for example CCA salts or a sodium chlorophenate, and are forcibly introduced into the wood by pressurised impregnation methods. The treating solution is kept inside the wood until the treating substances have been fixed in the wood by precipitation or chemical deposit. A significant rejection of worn-out treating liquid is obtained at the end of the method by reducing the pressure inside the pressurised treatment container to a value equal to, and preferably less than the pressure which prevailed in the wood immediately before impregnation. The speed and efficiency of the method are materially increased at a high temperature and it is often advantageous to heat the wood, for example by heating the treating liquid or else by evacuating the treating liquid from the container and by using steam or a second treating liquid for heating the wood. In any case, care must be taken to maintain sufficient pressure inside the treating container to prevent a premature rejection of the treating liquid before the substances have been deposited in the wood.
