By B. Domvin, Jii. There is littk doubt that the forms of single, compound,or triple engines have a good deal to do with steam condensa-tion, particularly as these forms generally mean considerablecold areas of condensation in contact with the hot steam temperature range in each cylimler has, accordingto results, much less influence than the temper-ature of the metal. When cylinder walls are heated till theirtemperature equals that of the steam, there is less condensa-tion per .square foot of internal surface than with non-heatedwalls. The indicator diagrams .show that the pressure andtemperature ranges are increased ; so that as compared withcooler surfaces, there is lens condensation and greaicr range,and experiments confirm this. Take the case of two modern triple engines by two differentmakers. Even when made for about the same po
