The purpose of this study is to modify the kerosene furnace, which is forced flue type with 15000kcal capacity, to gas furnace satisfying for CITY gas, LNG gas and LPG gas. The gas furnace, a kind of gas appliance, is mainly used for heating houses by combusion of gas. This paper describes briefly the design technology for gas burner which is most important in replacing kerosene fuel with gas fuel. Especially, the design for gas nozzle is constructed by theoretical and experimental method. It is found that the experimental results of the modified gas burner are good agreement with the theoretical results for calorific value and combustion efficiency. The result of this study will contribute in the design skill and of gas burner and similar gas appliance, and the pursuit for reduction of fuel cost as well as atmospheric pollution.

석유를 이용한 시설원예 난방이 90%를 넘고 있으며, 최근 유가의 불안정으로 시설원예 난방비 비중이 30%를 이상을 차지하고 있어 대체에너지를 이용한 난방비 절감기술이 절실하다. 현재 시설원예 면적은 약 52,189ha(채소, 화훼포함)이며, 이중 난방면적은 13,621ha로 전체 면적의 26%가 난발비의 부담을 안고 시설재배를 하고 있다. 이에 단위 열량당 연료비가 비교적 저렴한 코크스를 이용하는 난방기 중 온풍기를 개발하여 시설원예 난방비를 절감코자 본 연구를 수행하였다. (중략)

Electric or hydrogen energy source is expected to solve a various issues including energy security and exhaust pollution. However, it is required a lot of time and a variety of development to apply for commercialization. Therefore, it is needed to translation fuels between the future and the present. DME (Dimethyl Ether) can play a reduce exhaust emission from medium- to heavy-duty engines that are mostly used in commercial sector. It have applied to the DME fuel as a various alternative fuel including power generation in many countries. Especially, it is necessary to secure the energy of energy-poor areas that are widely distributed around the world. And Korea also has the energy-poor areas due to geographical characteristics. These areas has been covered by their own energy through some small diesel generators, diesel boiler etc. If DME fuels are supplied in new demand such as rural sector with energy poor area, DME fuel will be available in the wider sector. In this study, it investigated performance and emission characteristics of agricultural generator and air heater using DME fuel. So the existing equipment of generator and air heater was modified to apply DME fuel. And combustion characteristics and properties of exhaust gas according to the contents of the DME fuel were evaluated. DME fuel showed a potential application in agricultural generator and air heater.
