A Comprehensive mathematical model for ignition of coal-fired AFBC by the intake hot gas is reported in this paper.Of the submodels constituting the comprehensive mathematical model,four key ones,i.e.that of single coal particle combustion,mass balance of oxygen,solid matter balance and Energy balance are described.The calculation results have been shown in good agreement with the experimental data.The model can reasonably pridict the effects various operation combustions on ignition process.

本文介绍了我们所建立的流化床锅炉床下热烟气点火启动综合数学模型。模型由描述点火启动过程所涉及的流动、传热和燃烧等物理和化学过程的诸多子模型所构成。本文着重讨论了数学模型中的四个子模型:单颗煤粒多相反应和均相反应模型,氧量平衡计算模型,固相物质平衡计算模型和能量平衡计算模型。计算结果和试验结果进行了对比,两者较为吻合。利用本文模型可对不同容量的流化床锅炉点火启动进行模拟计算,为点火装置设计和运行操作提供合理参数。

Using method of statistical mechanics and maximum entrophy principle, we obtain that distributions of precipitation, mean depth and coefficient of runoff in a water shed can be described by a negative exponential function. In ahighmountainous basin, the maximum distributive area of precipitation, depth and coefficient of runoff is glacierized area. In this case, a calculation method of average mass balance for glaciers in a water shed has been suggested in this paper. We use the model to simulate the mass balance...

Using method of statistical mechanics and maximum entrophy principle, we obtain that distributions of precipitation, mean depth and coefficient of runoff in a water shed can be described by a negative exponential function. In ahighmountainous basin, the maximum distributive area of precipitation, depth and coefficient of runoff is glacierized area. In this case, a calculation method of average mass balance for glaciers in a water shed has been suggested in this paper. We use the model to simulate the mass balance of Glacier No. 1 at the Headwaters of the Urumqi River. The result is reasonable and well precise. For recovery of mass balance, the method is employed to the Kangxiwa River Basin of Muztagh Ata-Kongur Ata, East Pamir, and -123.5 mm/a of mean mass balance during 1960~1990 is worked out. Finally, the long-term trend of mass balance, together with hydrological response to mass balance and precipitation changing in Chinese Pamir, are discussed.

应用统计力学方法和最大熵原理,论证了高山流域内降水、径流和径流系数与其所占面积之间呈负指数关系,流域内的冰川分布区是各参数的最大分布区,从而给出了高山流域冰川平均物质平衡的计算公式。在乌鲁木齐河源1号冰川流域对公式进行了验证,结果说明此方法是可靠的,且精度较高。运用此公式对东帕米尔康西瓦河流域的冰川物质平衡进行恢复,1960~1990年平均值为-123.5mm/a。

For economic considerations, it is not necessary or worthy to conduct numerical simulation for prediction of depleted production performance for small condensate gas reservoirs. But the conventional material balance equation (Black Oil), only applying to black oil and dry gas reservoir, will produce a considerable error when used for condensate gas reservoirs. However, the generalized material balance calculation presented by Walsh may apply to all types of reservoir, including black oil, dry gas, volatile and...

For economic considerations, it is not necessary or worthy to conduct numerical simulation for prediction of depleted production performance for small condensate gas reservoirs. But the conventional material balance equation (Black Oil), only applying to black oil and dry gas reservoir, will produce a considerable error when used for condensate gas reservoirs. However, the generalized material balance calculation presented by Walsh may apply to all types of reservoir, including black oil, dry gas, volatile and condensate gas reservoirs. For a small condensate gas reservoir, the results of numerical simulation of depleted production performance are compared with the results of these generalized material balance calculation, which suggests that the method presented by Walsh can be more easily and widely used, and especially suitable to optimizing development of smaller condensate gas reservoirs unworthy of numerical simulation.

从经济的角度考虑 ,对小型凝析气藏衰竭式开采动态的预测往往不必或不值得进行数值模拟研究。常规物质平衡 (黑油 )计算方法只局限于黑油和干气藏 ,应用于凝析气藏则存在很大的误差。Walsh提出的广义物质平衡计算方法 ,可用于包括黑油、干气藏、挥发油气藏和凝析气藏在内的所有油气藏。文中将一个小型凝析气藏衰竭式开采动态的数值模拟结果与广义物质平衡计算结果进行了对比 ,结果表明 ,Walsh方法简便、应用更广泛 ,可用于规模较小、不适合进行数值模拟研究的凝析气藏的现场开发优化。
