Medium high pressure marine boilers, constructed for steamof 60 to 150 lbs. per square inch, are circular or oval iix crossflection, and are fitted with round interior furnaces and flues likeland boilers. There are many vanations of marine boilers,adapted to suit special circumstances. Fig. 23 shows a frontelevation and partial sections of a pair of such boilers and shows one of them in longitudinal vertical sectioii. Maxims and Instructions, 62 THE MAEINE STEAM Fig 22.
