This paper focuses on the design and operating aspects of a 10-MWe cavity-type, natural-circulation, steam-generating receiver for a central-receiver thermal power plant. The development of the receiver concept and the basic design features are described. The solar energy input analysis, thermal/hydraulic performance, and structural design of the receiver are discussed along with its control concept and transient operation. The design, construction, and testing of a 5-MWt scaled-down version of the 10-MWe receiver are summarized with emphasis on test objectives, scaling criteria, and design similarities to the full-scale receiver.

The dual receiver concept presented in this paper improves the adaptation of the central receiver to the steam cycle in a solar thermal power plant. By combination of an open volumetric air heater and a tubular evaporator the dual receiver concept profits from the advantages of these two concepts while their characteristic problems are avoided. The water is evaporated directly in the tubular steam generator; preheating and superheating are done in heat exchangers by using the hot air from the volumetric receiver. This paper presents a concept study that extends previous work on the 10MWel level (Buck et al., 2004, “Dual Receiver Concept for Solar Towers,” Proc. 12th Solar PACES Int. Symposium, Oct. 6–8, Oaxaca, Mexico) to a level of 100MWel, which is the expected power range of future plants. The results confirm the benefits of the new concept, resulting from higher thermal efficiency of the receiver and lower parasitic power consumption. The annual mean efficiency is increased from 13% to 16%. Advantageous are also the reduced thermal loads in the receiver components.

This paper takes the specific characteristics of pulverized coal room in thermal power plant as the starting point,firstly, this paper analyzes the process layout and structure selection, and then the structural design and vibration design requirements of coal crusher house are introduced in this paper. Finally, based on the engineering example, a new structure form of vibration isolation design is creatively proposed, which provides a new design idea for the practical engineering design

The Dual Receiver Concept presented in this paper improves the adaptation of the central receiver to the steam cycle in a solar thermal power plant. By combination of an open volumetric air heater and a tubular evaporator the Dual-Receiver Concept profits from the advantages of these two concepts while their characteristic problems are avoided. The water is evaporated directly in the tubular steam generator, preheating and superheating is done in heat exchangers by using the hot air from the volumetric receiver (Fig. 1). This paper presents a concept study that extends previous work on the 10 MWel level (Buck et al. 2004) to a level of 100 MWel which is the expected power range of future plants. The results confirm the benefits of the new concept, resulting from higher thermal efficiency of the receiver and lower parasitic power consumption. The annual mean efficiency is increased from 13% to 16%. Advantageous are also the reduced thermal loads in the receiver components.
