摘要:
A filtering method of flue gas of a boiler employing a filter apparatus integrated with ceramic filters and provided with a control mechanism for regenerating the ceramic filter by reverse cleaning and a detecting mechanism for detecting directly or indirectly unburnt component. Valves of a compressed gas are operated by a signal from the control mechanism when flying-over of the unburnt component is detected to thereby start at once frequent reverse cleaning wherein the compressed gas is blown into the cleaned gas spaces and thereafter the frequent reverse cleaning having a period shorter than four minutes continues until the flying-over of the unburnt component decreases to a small quantity.
摘要:
A system for recovering as power the pressure and sensible heat of the gas discharged from the top of a blast furnace by guiding the gas to a dry-type dust collector for the removal of dust while maintaining the gas at the furnace top pressure and introducing the gas into a turbine for expansion. To protect the dry-type dust collector when the gas is run off from the furnace at an abnormally high temperature, a gas channel extending from the furnace to the dust collector is provided with at least one injector, which injects a cooling fluid into the gas in response to a signal from a temperature detecting sensor disposed close to the gas outlet of the dust collector. The sensor which is positioned near the dust collector outlet detects the temperature without the time delay attributable to the deposition of dust. With use of the dry-type dust collector, the gas can be fed to the turbine almost without cooling for the recovery of an increased amount of power.
摘要:
Method in which a metal fuel in the form of molten droplets is brought into contact with water for reaction. The fuel comprises aluminum as a primary fuel component and at least one of lithium, magnesium, sodium, potassium and sodium-potassium alloy as an auxiliary fuel component and is used in the form of an alloy or a mixture of these fuel components. When used in the form of an alloy, the fuel is preheated to a molten state and injected into a reactor under high pressure, whereby the fuel is made into droplets and contacted with water vapor introduced into the reactor from another system. For use as a mixture, the fuel is made into a slurry the liquid phase of which consists singly of the auxiliary fuel component, and the slurry is injected into an atmosphere containing water vapor.

A human powered drive units each including a pair of a rotatable member having a sprocket and a supporting member having a sprocket, which are arranged up and down, and including a chain extended around the rotatable member and the supporting member, are disposed at left and right sides, respectively. The left and right rotatable members 1, 100 are fixed on a driving shaft 15. A chain ring 6 on which the load is applied is mounted on the driving shaft between upper rotatable member 1 and rotatable member 100. In each of the units, constraining means including a free crank (10 for the right-hand unit, and 1000 for the left-hand unit) and arm (11 for the right-hand unit, and 1100 for the left-hand unit), is provided so as to maintain perpendicularity of a shaft of the pedal relative to the plane in which the chain moves. By the rider kicking the pedal along the closed orbit including a linear orbit portion, the force transmitted to the pedal from the foot of the rider is efficiently converted to a rotational force in a longer period of time, thus increasing the power input.
摘要:
A method for operating a filtration apparatus for flue gas, which removes dust from flue gas discharged from a burner using mainly solid fuel, wherein incombustible powder is introduced into the filtration apparatus upon detecting or foreseeing coming of unburnt combustible dust from the burner, or upon detecting or foreseeing a temperature rise of the flue gas, and the incombustible powder is suspended in the dust-containing flue gas to suppress combustion of the combustible dust, or to suppress the temperature rise of the flue gas, in the filtration apparatus.

A supporting structure for ceramic tubes in a gas system in which a plurality of stages of tube support plates are provided in a substantially horizontal manner in a container, and ceramic tubes are supported with their axial lines being substantially vertical between the vertically adjacent tube support plates so that through holes formed in the tube support plates are communicated with the inner passages of the ceramic tubes, and metallic ring holders are respectively fitted to the outer periphery of the lower end portion of the tubes with interposed compacted layers while the metallic ring holders are in contact with the lower end faces of the tubes, and the ring holders are respectively in contact with and are supported by the tube support plates which are placed below the ring holders. Engaging means of the ceramic tubes to the tube support plates is also disclosed.
摘要:
High-pressure gas generating apparatus includes a gas generator body provided with a combustion chamber. The gas generator body has a primary propellant injector including orifices for injecting a primary fuel and orifices for injecting a primary oxidizing agent, both the orifices being open to the combustion chamber, an igniter for igniting the primary fuel forced out from the injector, and valve means having a secondary fuel injecting orifice for injecting a metal fuel into a high-temperature gas atmosphere to be reacted therewith and containing a secondary oxidizing agent produced by the reaction of the primary fuel injected from the primary propellant injector with the primary oxidizing agent similarly injected.

A pressurized fluidized bed combustion boiler system comprising: a boiler; a filtration apparatus with ceramics filters in a flue gas system; and a louver separator as a primary stage dust separator disposed between the boiler and the filtration apparatus.
摘要:
A filter unit comprises a plurality of plates made of an air-permeable, porous material which define particulate-containing gas passages and clean gas passages. The clean gas passages are formed at one side of each of the air-permeable, porous plates and the particulate-containing gas passages are at the other side in the direction intersecting each other. Particulates in an exhaust gas from a diesel engine deposit and accumulate on the air-permeable, porous plate while the exhaust gas is passed from the particulate-containing gas passages through the air-permeable, porous plates to the clean gas passages. A nozzle is placed in an outlet conduit, which is connected to the discharging side of the clean gas passages, to eject gas for back washing to thereby peel off and drop the particulates on the air-permeable, porous plates. A particulate receiving plate is provided to collect the particulates, which are burnt by a heater provided in the particulate receiving plate.
