In this article, problems concerning the type and capacity of the bypass system to be used on domestic " super-high pressure" units with emphasis on the capacity demands of peak load units. After making an analysis on the merits and defects of the various types of bypass systems, the author is of the opinion that the two-stage series-connected bypass system is the more sutable and that the capacity of the bypass system should be decided according to the type of the turbine-generator. For peak...

In this article, problems concerning the type and capacity of the bypass system to be used on domestic " super-high pressure" units with emphasis on the capacity demands of peak load units. After making an analysis on the merits and defects of the various types of bypass systems, the author is of the opinion that the two-stage series-connected bypass system is the more sutable and that the capacity of the bypass system should be decided according to the type of the turbine-generator. For peak load units, the bypass capacity should not be less than 50% of the boiler rated capacity.

本文讨论了国产超高压机组旁路系统的选型和容量问题,并着重论述调峰机组对旁路系统容量的要求。在分析了各种型式的优缺点后,作者认为采用两级串联布置的旁路系统较为合适。而旁路系统的容量应根据机组的类型而定。对于调峰机组,旁路系统的容量应取锅炉额定负荷的50%。

The temperature and stress fields of both original and modified LP inner casings are determined with measurement and calculation for a large capacity turbine. Fracture mechanics theory is employed in damage tolerance design and life prediction. The shortcoming in material selection and structure is discussed for the Original iron casting casing. The modified casing fabricated with plates and steel castings permits larger initial flaws, exhibits a better crack growth rate characteristic and better accessibility...

The temperature and stress fields of both original and modified LP inner casings are determined with measurement and calculation for a large capacity turbine. Fracture mechanics theory is employed in damage tolerance design and life prediction. The shortcoming in material selection and structure is discussed for the Original iron casting casing. The modified casing fabricated with plates and steel castings permits larger initial flaws, exhibits a better crack growth rate characteristic and better accessibility for inspection on condition that they meet the expectation of life. All these characteristics come to a conclusion the modified LP inner casing can be used not only in base load but alsp in peak load units.

在通过实测及计算分析得到大功率汽轮机原型与改型二种低压内缸温度场、应力场的基础上,应用断裂力学理论,对二种低压内缸进行了损伤容限设计及寿命分析。论述了原型铸铁内缸在选材、结构二方面所存在的问题,论证了改型的钢板——铸钢拼焊结构内缸具有可容限大的初始裂纹等特性。从而得出改型的低压内缸不仅可用于基本负荷机组而且用于调峰机组的结论。

Heat Accumulators in coal-fired power plants are useful for balancing boiler loads, reducing operating cost and initial investment, as well as improving enviromental conditions. Utilization of accumulators render an overall efficiency higher than peak-load unit and can also be used as a transient reservior of thermal energy. Accumulators have already found a wide application in oversea countries.
