172,712. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 8, 1920. Vapour engines. - In a boiler particularly intended for vaporizing mercury or other liquid having a high boiling point, of the kind described in Specification 152,785, the sections 15 consist of plates so corrugated and placed together as to form a number of tortuous passages of uniform width for the liquid and vapour. The sections are arranged with the tops of their corrugations in contact, thus forming a number of separate flues between the sections. The hot gases enter through a bottom opening 31, and pass upward through the centre flues 35, laterally through the upper flues 36, and then downwards through the side flues 37. The fluid enters at the bottom of each section on both sides, and is directed beneath partitions 19 towards the centre, and then, after passing upwards, is directed downwards around partitions 20. The fluid is preheated in side passages 21.
