摘要:
对稠油多元热流体发生器典型燃烧组分进行分析是注入能力评价、采收率预测、多次吞吐优化的关键。研究利用Fluent软件对多元热流体发生器进行三维仿真建模,模拟发生器不同工况下温度场和流场的分布。结果表明,不同的多元热流体发生器需要根据不同的燃料设计相应的燃料喷嘴,以促进燃料充分燃烧,提高热效率。当柴油作为燃料时,燃油喷嘴需要与空气喷嘴相匹配,以加强其雾化效果。天然气是多元热流体发生器的首选燃料,但在燃料供应条件有限的情况下,液态柴油和气相天然气可以相互替代,作为燃料在同一发生器中使用。当煤粉作为燃料时,即使有过量氧气,也难以充分燃烧。但是,在综合考虑成本或缺乏其他燃料时,可通过优化燃料喷嘴设计,最终实现煤粉在多元热流体发生器中的高效燃烧。
Abstract:
The measurement and analysis of typical combustion components of multi-component thermal fluid generator in heavy oil injection is the key to the evaluation of injection capacity, recovery efficiency prediction, multi-cycle injection optimization. In this study, three-dimensional simulation modeling of multi-component thermal fluid generator was carried out by Fluent to simulate the distribution of temperature field and flow field under different working conditions of fuel combustion chambers. The results show that corresponding fuel nozzles for different multicomponent thermal fluid generator need to be designed according to different fuel flow patterns to facilitate full combustion of fuel and improve thermal efficiency. When diesel is used as fuel, the fuel nozzle needs to be matched with the air nozzle to strengthen its atomization effect. Natural gas is preferred as fuel for multicomponent thermal fluid generators. And if fuel supply conditions are limited, the diesel in liquid phase and natural gas in gas phase could substitute each other as fuel in the same multicomponent thermal fluid generator. When pulverized coal is used as fuel, it is difficult to fully burn even if there is excessive O2. However, when considering cost or lack of other fuels, the fuel nozzle design can be optimized to finally realize the efficient combustion of pulverized coal in the multi-component thermal fluid generator.
