| 101 | Work recovery from process involving steam generation | US09846361 | 2001-05-02 | US06523348B1 | 2003-02-25 | Arun Acharya; Christian Friedrich Gottzmann; Bayram Arman; Dante Patrick Bonaquist; John Henri Royal |
| A method of conducting a process involving the generation of steam in which a hot process stream is generated. The hot process stream can be generated in any manner and can include a burner section of a steam methane reformer, a gas turbine of an integrated combined cycle, a combustion chamber used to pre-heat incoming air and oxygen for a blast furnace, an oxygen transport membrane system, and a gas turbine or natural gas engine that provided to compress air in a cryogenic air separation unit. Heat from the hot process stream is transferred to a thermoacoustic engine to recover work at high temperatures and to generate an intermediate temperature process stream therefrom. The intermediate temperature process stream is introduced to a steam generator to generate the steam. | ||||||

| A control spear serves to close and to controllably open a valve passage in a passage for conducting a dust-containing gas at temperatures of about 400.degree. to 1200.degree. C. The control spear comprises a shaft and a frustoconical head which cooperates with the valve passage. The shaft is movably mounted on the head and is preferably resiliently biased against the shaft. | ||||||
| 103 | Process and installation for the treatment of a stream of gas containing pyrophoric dust | US313512 | 1989-02-22 | US4959085A | 1990-09-25 | Maurits C. Van Camp; Philippe M. Wattel; Andre L. Delvaux |
| A stream of gas containing pyrophoric dust and oxyen is passed through a chamber that is equipped at the inlet with burners and sprinklers the operation of which is controlled in such a way that the stream of gas has for at least 1 second a temperature of at least 270.degree. and that the temperature of the stream of gas does not exceed 500.degree. C. Thereby the pyrophoric dust, that is present in the stream of gas is oxidized whereby is looses its pyrophoric character. The stream of gas is thus optimally conditioned to be filtered in a bag filter installation. | ||||||
| 104 | Shaft furnace bypass system | US112166 | 1987-10-26 | US4788917A | 1988-12-06 | David J. Hogue |
| A method and apparatus for removing undesired compounds such as alkali compounds from a shaft furnace such as a blast furnace. The process and apparatus includes providing a plurality of intermediate exhaust conduits or manifolds within the shaft furnace for withdrawing some of the furnace gases which may be rich in alkali or other undesirable compounds from the furnace while allowing the balance of the gases of combustion to rise through the furnace. These conduits are positioned so that the temperature below the conduits is higher than the temperature at which the alkali compounds will volatilize and the temperature above the conduits is lower than the temperature at which the alkali compounds will condense so that the undesirable alkali compounds are in a vapor state when they are withdrawn from the furnace through the intermediate exhaust conduits. These alkali rich gases are then exposed to a cool surface such as an abrasive material being pneumatically conveyed through the intermediate conduits so that the alkali compounds condense on the cool surface. An apparatus and method including a fluidized bed system is also disclosed for cleaning the abrasive material so that it can be recycled to the conduits within the furnace. | ||||||
| 105 | Device for shutting off a pipe | US756444 | 1985-07-18 | US4660805A | 1987-04-28 | Franz D. Hahn; Otto Heinemann; Heinz-Herbert Schmits |
| The invention relates to a device for shutting off a pipe using generally U-shaped spring steel strips as sealing elements, each such element comprising a pair of arms which converge toward one another form an arcuate web at an acute angle. The deformation of the two flat arms of these sealing elements is limited by two flat, rigid rolling surfaces which are tangential to the web. Such a construction is distinguished by satisfactory functioning and a long working life. | ||||||
| 106 | Process of afterburning and purifying process exhaust gases | US584913 | 1984-02-29 | US4539188A | 1985-09-03 | Martin Hirsch; Wolfram Schnabel; Harald Sauer; Hans-Werner Schmidt |
| A process for afterburning and purifying process exhaust gases, which contain combustible constituents, wherein the process exhaust gases and the oxygen-containing gases required for a combustion are separately supplied to a fluidized bed reactor of a circulating fluidized bed. In the fluidized bed reactor, the gas velocity is adjusted to 2 to 10 m/s (empty pipe velocity), the mean suspension density is adjusted to 0.1 to 10 kg/m.sup.3, the temperature is adjusted to 700.degree. to 1100.degree. C., and the stoichiometric ratio of gas-purifying agent having a particle size d.sub.p 50 of 30 to 200 .mu.m to pollutant contained in the process exhaust gas or formed by the combustion is adjusted to 1.2 to 3.0, calculated as Ca:S. The entrained solids in the gases from the fluidized-bed reactor are recycled to the reactor at a rate of at least 5 times the weight of solids contained in the fluidized bed reactor per hour. | ||||||
| 107 | Control system for an installation utilizing pressure energy of outgoing blast-furnace gas | US818167 | 1977-07-22 | US4192489A | 1980-03-11 | Vladimir A. Babich; Abram M. Vitlin; Arnold P. Kolchanov; Elena I. Sheveleva |
| The control system according to the invention has a number of control units, namely: a control unit for checking the installation for start-up readiness, a control unit for starting the installation, a control unit for synchronizing the electric-generator frequency and the power-line frequency, a control unit for increasing the load of the gas turbine, a control unit for monitoring the heating of the blast-furnace gas, a control unit for shutting down the installation, and a control unit for filling and emptying the installation, these units being appropriately interconnected. The proposed control system makes it possible to achieve fully automatic control of the installation for utilizing the energy of the outgoing blast-furnace gas pressure to improve the reliability thereof and to prevent damage to the equipment and hazards to the supervisory personnel. | ||||||
| 108 | Gas-cleaning apparatus and method for high-pressure blast furnace | US882421 | 1978-02-28 | US4152123A | 1979-05-01 | Karl-Rudolf Hegemann; Helmut Weissert; Theodor Niess |
| The gases emerging from a high-pressure gas furnace are subject to coarse particle separation and then to washing and scrubbing with water before driving an expansion turbine which has a gas bypass so that the turbine can be cut off. The scrubbing water recycled to the scrubber when the turbine is cut off, is permitted to traverse a cooler of the washing-water recovery unit but, when the turbine is operative, the scrubbing water bypasses the cooler. The water introduced into the scrubber can thus have a temperature of about 25.degree. C. when the turbine is bypassed and about 50.degree. C. when it is effective. | ||||||
| 109 | Apparatus for cleaning stack gas and using same for generation of electric power | US818675 | 1977-07-25 | US4145193A | 1979-03-20 | Karl R. Hegemann |
| Stack gas is first passed through a coarse-particle separator and then a prescrubbing tower. Then this gas, which is under pressure, is passed through a pair of differential-pressure (annular-gap) washers. The output side of one of the washers is connected directly to a droplet separator at the output of the system. The outlet of the other washer is connected through a turbine driving an electric generator and having its output side in turn connected to the droplet separator. The control body of at least the washer which is connected directly to the droplet separator is adjustable so as to maintain a constant backpressure in the system at the blast furnace from which the stack gas comes. The washer connected to the turbine is set up to pass at least four times as much of the gas as the other washers so that most of the gas passes through the turbine, undergoing a pressure drop that is transformed into the work of driving the turbine and generates electricity. | ||||||
| 110 | System for changing over of blast furnace top pressure control | US702128 | 1976-07-02 | US4067557A | 1978-01-10 | Masanobu Inubushi; Hajime Yamamoto; Toshiharu Ozaki |
| A control changeover system in a blast furnace system including a septum valve having a capability of controlling the furnace top pressure in the blast furnace system and a blast furnace gas energy recovery turbine also having a capability of controlling the top pressure by front pressure control is operated with a slight difference between preset values of the top pressure set by a top pressure setter respectively for control by the septum valve and control by the turbine, whereby the predominance in controlling the top pressure between the two control capabilities is automatically changed over from one capability to the other in accordance with an operation of varying the turbine load by means of a load setter provided for the turbine while the two control capabilities are maintained in operative state. | ||||||
| 111 | System for discharging flue gases | US23520872 | 1972-03-16 | US3844744A | 1974-10-29 | HAUSBERG G; HEGEMANN K |
| Flue gases from a high-pressure blast furnace are led from above into a vertical duct terminating in a tubular nozzle with a downwardly converging section and an adjoining cylindrical (or prismatic) section respectively coacting with a tapering portion and a cylindrical (or prismatic) portion of an insert defining therewith a pressure-regulating gap of adjustable width and a substantially invariable throttling passage. A spray head in the duct above the insert irrigates the gases descending through the nozzle into a separating compartment in which they undergo a sharp change of direction whereby they are freed from accompanying solids wetted by the spray. The width of the regulating gap may be controlled by a pressure sensor actuating a solenoid to displace the insert.

| 112 | Blast furnance top cone and steam control nozzle assembly | US3653647D | 1970-08-05 | US3653647A | 1972-04-04 | CARR HUGH B; BRADEL NORMAN F |
| A blast furnace top cone and steam control nozzle assembly including a housing mounted on the cone and having an end opened to the confines of the top cone. A nozzle member is supported by the housing at the open end thereof. A stop member is disposed in the housing and is engageable with the nozzle member for selectively opening and closing the nozzle. The steam is shut off at its point of injection into the blast furnace thereby preventing the hot blast furnace gases from entering the housing to cause damage therein. Also, shutting off the steam at the nozzle eliminates a need for a separate steam shutoff valve upstream of the nozzle.
