Abstract:
The present invention relates to a coal characteristic measuring apparatus with a pressurized reactor capable of rapid heating and, more specifically, to a coal characteristic measuring apparatus which can measure components by pyrolysis gasification of coal in a condition of various temperatures and pressures including a high temperature and high pressure condition, to identify the characteristics of the coal with various compositions and identify a proper gasification reactor and the operation condition of the gasification reactor for the corresponding coal, and especially, can be operated in a high pressure condition without extremely increasing the thickness of the reactor, and reduce the preheating time and the energy consumed for heating by rapid heating.
Abstract:
The present invention relates to an apparatus and a method for manufacturing combustible syngas from carbon dioxide, which is greenhouse gas, using a high-temperature microwave plasma-catalyst hybrid process. More particularly, the present invention generates a high-temperature plasma flame, of which the temperature is thousands of degrees, by supplying a plasma-generating device with carbon dioxide and a small amount of methane to be used as plasma-generating gas and fuel, and forms combustible syngas including hydrogen and carbon monoxide by forming a large amount of activated radicals that are in reaction-accelerating state owing to the generated plasma, and conducting reforming reaction at high temperature. In addition, radicals and ions generated from non-reacted carbon dioxide and methane by plasma accelerates conversion into combustible syngas using a catalyst in a catalytic reaction chamber installed at the end of a plasma reaction chamber, which is the end of the plasma flame, to intercommunicate, and reaction and combustible gas yield rate are improved by supplying the used catalyst to a catalyst regenerating chamber, regenerating the catalyst via combustion and re-supplying the catalyst to the catalytic reaction chamber to conduct catalytic reaction.
Abstract:
PURPOSE: A gasifier and an operation method is provided to produce a synthetic gas with fair quality generated for a relevant purpose by the selective work of a bottom up or top-down gasification using one gasifier. CONSTITUTION: A variable gasifier(10) is varied to work in the bottom-up or top-down gasification according to the purpose of use being supplied a fuel of coal, bio mass, RDF(refuse derived fuel), and RPF(Refuse Plastic Fuel). A purifier(20) refines the synthetic gas produced in a variable form gasifier. A cyclone(21) separates the solid particle from the synthetic gas ejected from gasifier. A scrubber(22) removes the foreign substance by spraying the washing water on the synthetic gas ejected in the cyclone. A filter(23) separates and removes the minute particle included in the synthetic gas passed through the scrubber. A bypass tube(24) directly transfers the synthetic gas passed through cyclone to a supply controller if there is an gasification reaction with upper flow. A supply controller(30) controls the supply direction of the synthetic gas refined in the purifier. A combustion boiler(40) and a gas engineer is operated being selectively supplying the synthetic gas by the supplying controller. An FD fan(70; Forced Draft FAN) is set up in the front end line of the second gasification material inlet. An ID fan(60: Induced Draft FAN) is set up in the rear end line connected with the synthetic gas vent. The synthetic gas supplied to a gas engine by a supplying controller is temporary storage in a reservoir(51). A fuel supply portion is formed and the fuel is inpoured from the fuel supply portion in an introduction chamber.
