Up to the present, 17.5 kg/cm2 G. and 365°C were the highest pressure and temperature in steam plants of merchant vessels, in this country.The steam condition of 27 kg/cm2 G. and 390°C was adopted in these new ships, where coal was the fuel, in order to improve the whole plant efficiency, also save weights and spaces of boilers.The three main boilers are the Mitubisi three drum type marine water tube boilers, having the heating surface of 385 square meters each, equipped with the Taylor multiple-retort underfeed stokers for burning the Fushun coal, the horizontal type convection superheaters and the tubular air preheaters.On the official sea trials of the S.
