This paper presents a static and dynamic simulation models of Heat Recovery Steam Generator (HRSG) with once-through evaporators and its application to investigate the load changes and startup processes for the combined cycles. The outstanding advantages of once-through HRSG (OT HRSG) are the rapid start-up/shutdown and operational flexibility. But it’ control system is more complex than drum type HRSG. Therefore, to design such a system, it is necessary to have computer models in detail. The OT HRSG models were made using commercial simulation software, APROS. The results of simulation for steady state, load changes, startup and shutdown operating processes were compared with the design data and gas turbine operating curves.

The purpose of this study is to confirm the structural reliability of the main component in HRSG by evaluating the structural integrity of HP drum according to EN code. The HP drum is the most thick-walled pressure vessel in HRSG, in which significant thermal stresses occur during the load change and transient operation. In this paper, transient temperatures and pressures determined by the dynamic simulation were taken into consideration, and thermal and structural finite element analyses(FEA) were performed to properly evaluate their effects. Using the results of the FEA, fatigue life of the HP drum was evaluated.

Gender were observed in higher overall satisfaction of a man, granted a high degree of satisfaction lower age, education elementary school, at least university graduates, found that satisfaction is high. In health, become clear that the more satisfied the more you health, spending money a month it became clear that the more satisfied the elderly to be used about 300,000 won to 500,000 won use period found that the elderly were more satisfied if less than one year and more than three years. In the region, Gangseo-gu is found to be slightly higher overall satisfaction with services than the Eunpyong-gu.

These days many p대ple are disterbed from eyestrain and the number is on the increase. So, through the oriental and occidental books I studied pysical and breathing exercises to help overcome eyestrain. The result were as follows; 1. The most common way is to close your eyes and rub them with warm palms. Then press or rub your eyeballs simultaneously. 2. There are two ways to exercise the eyeball by itself. One way is by looking at only one spot and the other way is to look four ways-first up, down, left and right-and then rotate right and left. 3. There are many different opinions that of the degree of strenth to be used in pressing the eyeball. I came to the conclusion that if we want to relex the eyeball, you must press it gently but to strenthen it, you must press it hard. 4. This method is a common way to press orbit or acupuncture points of the peripheral eyeball. For example B-1(晴明), S-2(四白), B-2(찬죽), Tae-Yang(太陽), TE-23(絲竹空), etc. 5. Since eyestrain is related to the whole body, it is known that you can relex your whole body by pressing the acupuncture points located in the head and posteriores cerviicis or by stretching the upper half of the body. 6. The best time to pratice is early in the morning or when you feel eyestrain. But I couldn't find a consistent on breathing method or the amount of time to practice.
