Abstract: Introduced the theory of the Energy loss analysis and lots of Energy loss analysis methods and utilized the basic formula method to analysis the influence of some operation parameters of a foreign designed 300MW coal-fired power plant to coal consumption in the variety loads. Applied matlab to make a figure, which contained the influence of some operation parameters of a foreign designed 300MW coal-fired power plant to coal consumption in the variety loads. Compared analysis the results, and gained the energy saving direction, so it conducted the operation of these units and optimized it.

Abstract: The finite element model of supercritical boiler water-wall has been established and the ANSYS10.0 was used to simulate cross-section temperature distribution. The simulation result shows that fin-point is the highest temperature on the whole water-wall cross-section. As the fins thickness changed, fin-point temperature has a optimal value；Basing on some 600MW supercritical boiler, it has an optimal value when the fins thickness ranged from 7mm to 9mm.

Abstract: In the view of heat pipe position optimization of transformers cooled by heat pipes, using the thermal equilibrium equation and the empirical formula of heat transfer coefficient of the evaporation and condensation section, applying Newton Iteration, computing the optimal condensation section area, the optimal computation of heat pipes’ position is implemented and the model of heat pipe position optimization of transformers cooled by heat pipes is set up.
