Show Combustion of Coal-Water Mixture in Teat Furnace by Isao Koyama * 1 Kunio Okiura *2 Yoshitaka Takahash* *1 Abstract (Preface) In the development of highly loaded coal-water mixture (CWM), the number of study groups and the fields of research items are rapidly increasing in Japan. Under these circumstances, Hitachi initially introduced the Co-AL slurry technique and successfully performed the combustion test in September, 1982. However, the combustion characteristics are largely influenced by the slurry properties so that wider tests and studies including slurry preparation, production, transportation and storage became necessary for the completion of combustion technology. Therefore, further development is continued as an overall system with each facility of slurry handling processes Regarding the combustion test, the multi-burner furnace of c kO x 10° Btu/h heat input was firstly used to confirm the potential of the CWM application in utility boilers. And the single burner test of 2 x 10" Btu/h has also been conducted in order to study the combustion performance and characteristics when the conditions of fuel and operation are changed. This paper describes the main research substances and results performed up to date. *1 Kure Works, Babcock-Hitachi K.K. *2 Kure Research Laboratory, Babcock-Hitachi K.K. |
