If the size of the crack in the pressure boundary of the pressurized light water reactor coolant system is very small, the coolant is vaporized and spreads into the containment vessel at the beginning of the leakage, and ...

Batch type reduction-oxidation tests were performed to compare combustion characteristic of mass produced particle (N016-R4) for syngas from glycerin with natural gas in a 0.5 MWth chemical looping combustion system. ...

Continuous solid circulation test at high temperature and high pressure conditions and batch type reduction-oxidation tests were performed to check feasibility of a 0.5 MWth chemical looping combustion system. Pressure ...

To check applicability of recently developed new oxygen carrier for 0.5 MWth chemical looping combustion system, reactivity tests were carried out at high temperature and high pressure conditions. Pressure, temperature, ...

Thermal analysis was performed for a cold box of a hydrogen liquefaction pilot plant with 0.5 ton/day capacity. The pilot plant has adopted a hydrogen liquefaction process using two-stage helium Brayton cycle with precooling ...

Reflow process conditions were investigated for 0402 electric parts with Sn-3.0Ag-0.5Cu solders. Circle hole shape metal mask with 100 m thickness showed excellent printability. Self alignment abilities were 71% for 1005 ...

A 1 GPa class weld metal was prepared by multi-pass welding using a prototype flux-cored wire, and the correla�tion between microstructure and low-temperature impact toughness of the weld metal was investigated. The ...

This paper presents the performance characteristics of a 1 kW solid oxide fuel cell (SOFC) stack under various internal reforming and fuel utilization conditions. The Research Institute of Industrial Science & Technology ...

The availability of the thermal energy has been deeply recognized recently to encourage the cascade usage of thermal energy from combustion. Within the framework, a 1 kW class Stirling engine based cogeneration system has ...

최근, 고효율 1,000 MW 급 대용량 화력발전소가 증가하고 있다. 이러한 대용량 화력발전소의 안전운전을 위한 핵심설비로서 3,600 rpm으로 고속 회전하는 초대형 증기터빈 속도 제어시스템의 건전성 확보가 매우 중요하다. 본 논문에서는 건설발전소에서 최초 증기터빈 기동 전 속도 제어 알고리즘의 건전성을 검증하고자 한다. 이에 따라 동일 조건으로 운영 중인 국내 화력발전소 운전 데이터 및 ...
