Topping Turbines: Adding New Life to Older Plants
No full textAn existing power plant can be repowered at a modest investment cost through a topping turbine installation. Essentially, this consists of replacing the existing old, low pressure boilers with new, high pressure boilers and adding a new, high pressure, non-condensing turbine (topping turbine) .
The high pressure steam generated in the new boilers is supplied to the throttle of the high pressure turbine and exhausted at the pressure required by the existing, old, low pressure, condensing turbines. The exhaust from the topping turbine is then supplied to the throttle of the existing turbines.
The additional capacity results from the kilowatts generated in the topping turbine while reducing the steam pressure from the throttle to the exhaust conditions. Also, because this steam is not condensed, there is no loss of the latent heat of condensation of the steam to the condenser circulating water. Consequently, the thermal efficiency of the cycle is considerably enhanced

The political roots of city managers in Kansas
No full textForeword by H. Edward Flentje and Chase M. BillinghamCities across Kansas adopted the manager form of government in the twentieth century. This structure, wherein most administrative responsibilities are delegated to a professional manager appointed by a local elected governing body, was designed as a model of “good government”; it would depoliticize local government, professionalize civil service, and root out corruption, graft, and scandal. Despite its nonpolitical orientation, implementing the manager plan involved highly politicized and partisan campaigns in the 1910s, especially in the city of Wichita, where the proposal faced substantial resistance. This article by H. Edward Flentje, originally published in Kansas History in 1984, traces the origins of the manager from of government, its major proponents (especially Wichita Beacon publisher and future governor and U.S. senator Henry J. Allen), and the political struggles that ensued, leading ultimately to its spread across Kansas. In the new foreword to the reprinted article, Flentje and urban sociologist Chase M. Billingham provide historical and political context, update some of the original findings, and situate the legacy of this research within the tradition of urban historical scholarship in Kansas
