AbstractAbstract
[en] The reader will achieve a benchmark understanding of the essence of cleaning for the removal of contaminants from machine elements by means of cryo jet/ water-ice jet with particles prepared beforehand. This paper represents the classification of the most common contaminants appearing on the surfaces of machine elements after a long-term service. The conceptual contribution of the paper is to represent a thermo-physical model of contaminant removal by means of a water ice jet. In conclusion, it is evident that this study has shown the dependencies between the friction force of an ice particle with an obstacle (contamination), a dimensional change of an ice particle in the cleaning process and the quantity of heat transmitted to an ice particle.

AbstractAbstract
[en] Korean public housing ventilation systems mainly use natural ventilation and local exhausts. When a local exhaust is operated in a narrow space such as a kitchen, the air pressure loss can lack balance. A decrease in hood capture efficiency and ventilation effectiveness causes the problem that people in the living room can be exposed to PM2.5 generated by cooking. Therefore, it is necessary to develop an effective ventilation strategy for the local exhaust, considering the make-up air supply. In this study, a ventilation system that integrates the range hood and ventilation systems (e.g., heat recovery equipment and auxiliary air supply) was developed to resolve this issue. Multi point measurement was conducted using five low-cost sensors to determine the location of the sensors in the kitchen and living room. TSI-DustTrak 8532 and OPS3330 were performed with different ventilation system operating types. When the range hood was operated for one hour, the concentrations in the kitchen and living room were significantly high; 676 μg/m3 and 373 μg/m3, respectively. After the integrated operating algorithm was installed, the kitchen concentration was 185 μg/m3, and the living room concentration was 68 μg/m3. With an additional flow rate of 50 CMH through Heat recovery ventilator (HRV) the reduction in the concentration of PM2.5 was more effective. As a result, this advanced system was able to remove up to 60% of PM2.5 generated by cooking. The integrated system of the auxiliary air supply and range hood was evaluated to be effective in preventing the distribution of kitchen pollutants. (paper)

AbstractAbstract
[en] The present invention provides a hybrid power facility having a high power efficiency without introducing a fluid containing radioactivity directly to an exhausted heat recovering boiler and not releasing it to atmosphere. Namely, a gas turbine power plant is built together with a BWR power plant, and the exhausted heat recovering boiler is connected to the gas turbine. An intermediate loop for connecting a main steam heater and a lower pressure feedwater heater is disposed to a heat transfer tube in the boiler. The heat of the exhausted heat recovering boiler is taken out by using purified water, nitrous acid type molten salt or a liquid metal as an operation fluid of the intermediate loop, and steams at the exit of the reactor are further heated to a high temperature by the heat. Then, since temperature difference as a highly overheated source is increased by thus using the exhausted heat of the gas turbine power plant, the power generation efficiency is improved remarkably.

AbstractAbstract
[en] As a part of the project 'development of hydrogen production technologies by high temperature electrolysis using very high temperature reactor', we have developed an electrolyzer model for high temperature steam electrolysis (HTSE) system and carried out some preliminary estimations on the effects of heat recovery on the HTSE hydrogen production system. To produce massive hydrogen by using nuclear energy, the HTSE process is one of the promising technologies with sulfur-iodine and hybrid sulfur process. The HTSE produces hydrogen through electrochemical reaction within the solid oxide electrolysis cell (SOEC), which is a reverse reaction of solid oxide fuel cell (SOFC). The HTSE system generally operates in the temperature range of 700∼900 .deg. C. Advantages of HTSE hydrogen production are (a) clean hydrogen production from water without carbon oxide emission, (b) synergy effect due to using the current SOFC technology and (c) higher thermal efficiency of system when it is coupled nuclear reactor. Since the HTSE system operates over 700 .deg. C, the use of heat recovery is an important consideration for higher efficiency. In this paper, four different heat recovery configurations for the HTSE system have been investigated and estimated

Both for co-gen and combined cycle systems, supplementary firing of GT exhaust gas is normally required. Hence, duct burners have significant role for effective contribution towards of efficacy of heat recovery system for gas turbine exhaust gas. This article details on various aspects of duct burners in heat recovery systems. (author)

AbstractAbstract
[en] Absorption of low temperature steam in the acid concentrate raises the temperature of diluted acid stream. Heat pump based on this principle, called as acid absorption chemical heat pump (AACHP) is coupled with high energy demanding separation unit like distillation column to reduce the heat requirements. This article highlights the advantages of employing AACHPs. AACHP eliminates the need for sophisticated compressors. AACHP based on acid-water system is described. About 95% of supplied heat to the distillation unit is wasted through the cooling water to the environment, but net saving in heat is found to be approximately 40% if a distillation column is coupled with AACHP.(M.G.B.)
