Abstract: 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.
