In order to address climate change, reducing emissions of greenhouse gases mainly require carbon dioxide from burning fossil fuels for the effective capture and storage. Oxygen-enriched combustion flue gas because it can provide high concentrations of carbon dioxide, it is a very promising carbon capture technology, while its carbon dioxide emissions can also be a major source of thermal power plants applications.So for the oxygen-enriched combustion in thermal power plant flue gas application of one of the difficulties in the oxygen-rich coal combustion flue gas in the air with different characteristics and different research topic selected for the oxygen-rich coal combustion in the flue gas fire research. In this study, the combination of experimental and calculation methods for coal fire in the oxygen gas properties in the study. Through the test-bed coal combustion for domestic and international research to determine the experimental use of dropper furnace as the main experimental apparatus, and the detailed design of the experimental units.FLUENT simulation using pulverized coal furnace in the experimental stage on fire dropper process, by analyzing the simulation data of the temperature and the amount of carbon dioxide generated to determine the coal fire in the way of oxygen in flue gas obtained in the drops of coal Tube Furnace in the ignition time and location. Analysis of the temperature and carbon dioxide at different times of the curve, combined with theoretical knowledge of fire, suggesting that coal burning furnace in the process of dropper and some features, such as:the impact of carbon monoxide in oxygen concentration and so on. To guide the implementation of the experiment to guide experimental measurements such as temperature and the amount of coal, making the test more accurate for further experimental studies provide a basis for oxygen gas.
