驱油用燃气锅炉富氧燃烧碳捕集方案研究

Study on Carbon Capture Scheme of Oxygen-rich Combustion in Gas-fired Boiler for Oil Displacement

针对油田驱油用22t/h注汽天然气锅炉进行富氧燃烧碳捕集研究。燃气锅炉的烟气加补充纯氧作为锅炉的助燃气体,通过计算机软件模拟预测锅炉本体的热力学数值,考察这种碳捕集工艺流程对燃气锅炉热效率的影响及排放烟气中的最大CO_(2)体积分数。

Carbon capture in oxygen-rich combustion of 22 t/h steam injection natural gas boiler for oil displacement was studied.The flue gas of a gas boiler is supplemented with pure oxygen as the combustion auxiliary gas,and the thermodynamic value of the boiler is predicted by computer software to investigate the influence of the carbon capture process on the thermal efficiency of the gas boiler and the maximum CO_(2) concentration that can be achieved by the flue gas emitted from the gas.
