페로니켈 제조 공정에 있어서 석탄의 비중은 총 에너지원 중 70%에 상당하며, 온실가스 배출 또한 65%에 달한다. 이에 석탄을 대체할 물질로서 RPF, RDF, Biomass, TDF 등을 고려하였으며, 자체 개발한 열정산 프로그램을 활용하였다. 해석결과 석탄 대체물질의 사용할 경우 페로니켈 제조공정의 에너지 비용을 상당량 저감할 수 있을 것으로 기대된다.

In this study, the validity study has been carried out to apply the combustion burner in an electric arc furnace. The validity of applying the combustion burner has been studied in the aspect of the operation through the calculation of heat balance. The average decrease rate of power on time is 11.2%. When the maintainability is compared to the door lance manipulator type, the multi-functional combustion burner is simple to replace and repair. The location of burner can be adopted according to the drawings which are recommended in this study. As a result, the validity of applying the combustion burner to improve an efficiency of electric arc furnace has been confirmed.

The energy recovery rate estimation method proposed through the Waste Control Act does not take into account the energy used in practice. In addition, the method for measuring a lower heating value, which is the main factor of the energy recovery rate, was carried out through a small sampling amount, and thus the representative value of the waste was not reflected. With the revised estimation method (Notification No. 2015-215 of the Ministry of Environment), the energy recovery rate should be estimated based on the actual amount of energy used, and a heat balance method was proposed as a way to estimate the lower heating value. In this study, the lower heating value was estimated for seven industrial waste incineration facilities according to the revised estimation method. All data used in the estimations were achieved from measurement instruments applied to each of the incinerators and through direct measurements taken by the operators for the purposes of calculation. As a result, the lower heating value was estimated to be about 3,404.7 kcal/kg for the seven industrial waste incineration facilities.

A thermal analysis method taking into account energy balance in each elements of heat exchanger was introduced. This method has a merit in predicting the temperature field over the heat exchanger in detail. To verify this method, the results were compared with the published ones. The thermal analysis of the radiator in vehicles was also conducted and the results were compared with experimental ones. It is concluded that this method can be used in thermal analysis with relatively small error. When the velocity profile of inlet air is not uniform, the outlet temperature of cooling water is higher than that of uniform velocity profile.

In this paper, the cupola heat balance has been carried out by using programmable calculator with BASIC language. Computers tend to be used in almost every fields but for many people, computers are not handy yet because of its high equipment cost and its difficult language system. In view of this fact, a desk-top or a hand-held programmable calculator is the pertinent device in its calculation speed, accuracy, and easy programming language (BASIC), let alone its low cost. There have been some attempts to apply them to the foundry,${^{1),2)}}$ but they are little in number. This paper is the first attempt to apply the programmable calculator to the calculation of the cupola heat balance. After several applications in some practicalcases, the program has resulted in very satisfactory results such as saving of time and accuracy.
