A novel, patented topping power cycle is described that takes its energy from a very high-temperature heat source and in which the temperature of the heat sink is still high enough to operate another, conventional power cycle. The top temperature heat source is used to evaporate a low saturation pressure liquid, which serves as the driving fluid for compressing the secondary fluid in an ejector. Due to the inherently simple construction of ejectors, they are well suited for operation at temperatures higher than those that can be used with gas turbines. The gases exiting from the ejector transfer heat to the lower temperature cycle, and are separated by condensing the primary fluid. The secondary gas is then used to drive a turbine. For a system using sodium as the primary fluid and helium as the secondary fluid, and using a bottoming Rankine steam cycle, the overall thermal efficiency can be at least 11 percent better than that of conventional steam Rankine cycles.

Ignition Delay Period

In this paper, the thermal ignition delay period of the gasoline-air mixture under the condition of high temperature heat source and temperature-rising heat source in cave depots has been studied using experiment methods. The rules, scopes, and mechanism of thermal ignition delay period are got. It is found that: there is different delay period scope in different ignition model. The delay period for thermal explosion is the shortest, for thermal deflagration, the delay period is longer than that for explosion, usually seconds to a few hundred of seconds.The mechanism of delay period is unification of chemical kinetics and thermodynamics before ignition.

Sludge is the solid waste that generated during the sewage treatment process, because of high moisture content limits the final disposal and utilization. In this paper that solar and reclaimed water as heating heat source, It's not easy to design a new drying procedure that solar energy and reclaimed water heat pump with double high-temperature heat source, the system could make full use of respective advantages which of the solar energy, the hot of reclaimed water and heat pump. It would enhance the dehydration ratio, and high efficiency, lower energy consumption, sludge of moisture content (MC) decreased greatly; have created favorable conditions for the reuse. Technology what solar energy, air and reclaimed water heat pump with double high-temperature heat source were used to deal with sludge, the solar energy and air source heat pump were the main heating source. When the heat was insufficient, reclaimed water heat pump was turned on as energy supplementary. The dry air (70°C) was pumped into drying room continually; the moisture content (MC) of sewage was shrunk from 75% to 40% after drying.
