  • Patent number: 9034147
    Abstract: A method for reducing the coking time in the oven area near the door or end wall and for improving coke quality and situation of emissions by compensating for radiation losses through coke oven chamber doors and end walls is described. This compensation is accomplished by varying the height of the coal cake in the environment of the frontal coke oven chamber doors. The variation is achieved both by increasing or decreasing the coal cake over part of the length or over the entire length of the coke oven chamber door. The reduction in the height of the coal cake can be generated by omission of coal or coal compacts, the increase in height can be accomplished by stacking of coal and pressing or adding of coal compacts, with it also being envisaged to omit the pressing cycle so as to obtain a recess with a lower coal cake density which also has less heat radiation.

  • Patent number: 8951391
    Abstract: A solar distillation apparatus utilizing a substantially vertical reactor assembly is disclosed. The reactor includes a tubular outer shell, a base, a cap, and a central tension member. The annular space between the outer tube and the central tension member forms the reactor chamber. Seawater or other feed liquid enters the reactor chamber through the base plate. Reflected or direct solar energy heats the feed liquid, generating low pressure vapor. The vapor exits the reactor through the cap structure or the base. The concentrate left behind settles by gravity to the bottom region of the reactor's liquid column. Extension tubes on the feed openings allow feed liquid to enter the liquid column above the concentrate layer and avoid excessive mixing of the feed liquid and the concentrate. The concentrate exits the reactor through one or more openings in the base.

  • Patent number: 8821693
    Abstract: A heat-resistant door device for closing a horizontal coke oven chamber is made of a refractory material, using a material containing silica or a material containing silica and aluminum oxides, in particular. The material has a low temperature expansion coefficient and it is thermally well insulating so that the door is not deformed and/or distorted during the coal carbonization process. The door device is built of a coke oven wall mainly located above the door and embracing the door as well as of a mobile door located underneath. Thereby less cold ambient air enters into the coke oven chamber and radiation losses are minimized. The door may be comprised of an ellipsoidal bulge by which the coke can be better pushed into the coking chamber. The oven wall embracing the oven door can also be made of a refractory material containing silica or of a material containing silica and aluminum oxides.

  • Patent number: 7067043
    Abstract: A coke oven has a coke-oven chamber adapted to hold a mass of coke, defining above the mass of coke a gas-collecting chamber, and having a door opening. A door closes the door opening. A peripheral gas channel extends around the opening between the door and coke-oven chamber and has at least one outer and at least one inner door seal defining an annular space. The inner door seal is formed in both the coke-oven chamber and the gas-collecting chamber with a plurality of throughgoing holes forming fluid-communicating connections between the coke-oven chamber, the gas-collecting chamber, and the annular space at different heights of the coke-oven chamber and of the gas-collecting chamber. Thus regions of the coke-oven chamber with different gas pressures communicate with each other and with the annular space via the connections on the inner door seal to equalize pressure between the regions and the gas-collecting chamber.

  • Patent number: 7037408
    Abstract: A safe, efficient and repetitively operable coke vessel decoking system is disclosed. In a preferred embodiment the closed system comprises a coker vessel pressure-tightly sealed to a top head system, which includes a closure housing with a laterally moveable horizontal closure member therein and a cutting head enclosure, which further comprises a drill stem guide, an access door, and a cutting assembly mounted therein. A novel feature of the invention is a steam purge/blocking system whereby steam pressure is maintained in the closure housing during the coking cycle to maintain seal integrity. Personnel safety during decoking operations is greatly enhanced by eliminating dangerous manual tasks associated with the prior art such as unbolting and removing top head devices. The system can be remotely and repetitively operated through numerous coking/decoking cycles without removal of any system element.

  • Patent number: 6989081
    Abstract: The present invention features systems and methods for de-heading a coke drum without having to physically remove the head units. This is accomplished using a de-header valves that may be removably coupled to a coke drum. The de-header valve is equipped with, a valve closure and a seat support system capable of forming a continuous contact seal during the coke manufacturing process. Actuation of the valve closure functions to open and close the de-header valve. Once the drum is full, the de-header valve may be actuated (opened), wherein the coke that has accumulated on the blind is sheared by the seat support system, thus effectively de-heading the coke drum and facilitating the decoking process.
