Carbon negative emission methods, a nitrogen oxide ultra-low emission system, an air supply device and a flow control module. The system for use in carbon negative emission methods enables biomass to produce inorganic carbon and pyrolysis gas/gasification gas to realize negative emission of carbon. The nitrogen oxide ultra-low emission system enables fuel to be in mixed combustion with the pyrolysis gas/gasification gas to remove nitrogen oxides, which realizes ultra-low emission of the nitrogen oxides. The air supply device is in communication with a biomass pyrolysis coupling partial gasification and is in communication with the system for use in carbon negative emission methods and the nitrogen oxide ultra-low emission system. The pyrolysis gas/gasification gas enters the nitrogen oxide ultra-low emission system. The flow control module controls a flow ratio of a pyrolysis agent/gasification agent entering the system for use in carbon negative emission methods and flow of the pyrolysis gas/gasification gas and air entering the nitrogen oxide ultra-low emission system.

Control method for a system having reduced nitrogen oxide emissions and for use in a carbon negative emission method

In the technical field of power generation, a method and system for directly and rapidly detectingC of carbon dioxide, which can quickly complete aC activity measurement of carbon dioxide, while further improving uniformity and accuracy for directly and rapidly detectingC of carbon dioxide. The method includes: pressurizing and liquefying gaseous carbon dioxide to obtain liquid carbon dioxide; mixing the liquid carbon dioxide with a cosolvent and a scintillator in a pressure vessel to obtain a mixed solution; and placing the pressure vessel in a liquid scintillation counter for carrying out radiocarbon activity detection.
