This invention discloses a graphene oxide / carbon nanotube-based coal combustion catalyst, its preparation method, and its applications, belonging to the field of catalytic combustion technology for efficient coal utilization. First, graphene oxide is used as a carrier, and then carbon nanotubes and manganese oxide are grown on its surface in a one-step process using condensation and redox reactions, followed by co-firing with coal. The graphene oxide / carbon nanotube-based combustion catalyst prepared by this invention effectively improves combustion efficiency, reduces the ignition temperature of coal, and lowers the reaction activation energy, resulting in significant economic benefits and broad application prospects.

This invention provides an oxygen supply mechanism for a pulverized coal combustion device, comprising an oxygen-enriched channel, a central body, and a control component. One end of the oxygen-enriched channel is a nozzle extending through the pulverized coal channel, while the other end is located outside the pulverized coal channel and connected to an oxygen evaporation device. The nozzle includes a gradually expanding section that points outward along the axial direction of the nozzle, with its inner diameter gradually increasing. The central body is adjustable within the nozzle along its axial direction, forming an annular flow channel between the central body and the inner wall of the nozzle. One end of the control component is connected to the central body, and the other end extends to the outside of the pulverized coal channel. This oxygen supply mechanism allows for adjustment of the annular flow channel area by changing the position of the central body, enabling flexible control of the oxygen flow rate. This ensures optimal mixing of pulverized coal and oxygen under different load conditions and pulverized coal concentrations.
