当社では，天然オリノコと水のエマルジョン燃料であるオリマルジョンの発電用燃 料としての実用化を目指し，１９８６年から種々試験・研究を推進し，１９９１年 から鹿島北共同発電（株）２号ボイラにて国内初のオリマルジョンだき改造を行っ た。ここでは，１９９４年に将来の燃料多様化に備え実機スケールの各種実証試験 を行うため，国内事業用ボイラとして初めてオリマルジョンだきに改造した関西電 力（株）大阪発電所４号ボイラの例に基づいて，オリマルジョンだきの改造概要及 び運転実績を紹介する。 （著者抄録）
Orimulsion, Orinoco-oil emulsified with water, has been the subject of a study for practical application as a fuel for utility boilers, and MHI has conducted various research & development works since 1986. And in 1991 the Unit No.2 boiler of Kashima Kita Joint Electric Power Co. was modified for OrimulsionR firing for the first time in Japan. This paper describes the features of the modification for OrimulsionR firing and field operating data of the boiler based on the experience at the Unit No.4 Boiler of The Kansai Electric Power Co., Inc. which was the first utility boiler to be modified for OrimulsionR firing in Japan in order to demonstrate many kinds of large-scale tests for the variety of fuels in the future.
