基于能量守叵、质量平衡原理和热力学特性，提出了熔融碳酸盐燃料电池的数学模型，该模型考虑了电解质基块内的质量传递，以及质量传递对燃料电池内部热力学特性的影响，采用加权残差（MWR）数值方法和Matlab环境的系统函数化解偏微分方程组并建立动态仿真模型。仿真表明燃料电池内部各点的温度有较大的差异，随着燃料和氧化剂量的变动（增加），电极电解质的温度增加，而氧化剂流的温度有所下降。模型的物理参数是从某燃料电池研究所1.5kw熔融碳酸盐燃料电池获得。

针对汽轮机组各种运行方式的特点（包括优点和缺点），从能量供需协调的角度出发，提出了机组柔性控制，该控制方法结构简单，调整方便，不带非线性环节，具有明显的减弱锅炉汽压广义对象非线性的作用。对于不同的机组都可以通过调整个参数能量供需协调度α，得到满足主汽压波动小、机组负荷适应性强的控制系统，该控制系统适用于机组在大范围的不同工况下运行。仿真表明了这结果。

在指出了在单元火电机组中锅炉汽压广义对象非线性动态特性产生的原因的基础上，比较了功频调节和纯速度调节对锅炉汽压广义对象动态特性的影响，分析了功频调节对锅炉汽压广义对象非线性动态特性的线性化作用。进一步的研究表明，在负荷扰动（外扰）的情况下，功频调节对锅炉汽压广义对象非线性动态特性具有很强的线性作用；在大范围变工况情况下，采用功频调节时锅炉气压广义特性具有良好的全局性能一致性。这对用一性系统理论分析火电机组机炉特性和设计单元火电机组控制系统具有重要的指导意义。

CSIRO is developing a ventilation air methane catalytic combustion gas turbine technoIogy which is not only thermodynamically viable but also promises to use a much greater proportion of ventilation air compared with other technologies. This catalytic turbine can be used not only to mitigate methane in the ventilation air, but also to recover the energy released by methane oxidation to generate electricity. This paper briefly summarises the development of 1% CH4 catalytic turbine system based on the methane catalytic combustion experimental results and the design criteria determined for mine site application, and mainly presents the results of technical and economic analysis of the 1% CH4 turbine implementation into two Australian gassy mines, compared with the 16% CH4 turbine, based on real methane emission data over one year period. The characteristics of methane emissions are also presented. The 1% CH4 catalytic turbine significantly reduces the quantity of drainage gas required as a supplementary fuel to even out ventilation air fluctuations and to sustain the turbine system operation, and 1% CH4 seems to be a good combination of CH4 in ventilation air and drainage gas for a gassy mine. This turbine should be easier to manufacture than normal industrial gas turbines as it operates at low temperature and low pressure without cooling and dilution air. This technology, in its full scale implementation, promises to use between 80 and 100 percentage of fugitive methane emissions from gassy coalmines
