The “Kinjosan Maru” is the first ship equipped with Howden Johnson improved Scotch boiler and Gotaverken turbo-compressor. The propelling machineries consist of two sets of boilers designed for working pressure 16 kg/cm2and steam temperature 315°C, and one set of triple expansion surface condensing reciprocating steam engine specially designed to suit Gotaverken turbo-compressor and superheated steam. The engine develops a normal output of 1950 I.H.P. at 82 r.p.m.The trials were carried out at a light loaded condition and the results were quite satisfactory. The maximum speed of 14-5075 Knots was recorded at 89·75 r.p.m. and 2, 324 I.H.P. and the coal consumption trial shows reasonable results and the mean consumption was 0.445 kg/I.H.P.-Hr.
