The heat that passes from the furnace into the? inter plate is carried away, in part, by conduction in this plate (towards theright in the illustration), and in part it is transmitted directly through the twoplates (upward in the illustration) towards the water in the boiler, althoughthere is considerable resistance opposed to its passage in this last-mentioneddirection. The general effect is, that there is a sort of accumulation of heat inthe outer plate, as is suggested in the diagram. It is to be noted, too
The Locomotive . darkest regions corresponding to theregions of highest temperature. The heat that passes from the furnace into the? inter plate is carried away, in part, by conduction in this plate (towards theright in the illustration), and in part it is transmitted directly through the twoplates (upward in the illustration) towards the water in the boiler, althoughthere is considerable resistance opposed to its passage in this last-mentioneddirection. The general effect is, that there is a sort of accumulation of heat inthe outer plate, as is suggested in the diagram. It is to be noted, too, that thetemperature of the inner lap of the joint is lower than that of the outer one,not only because the inner lap is nearer to the water, but also because a certainproportion of the heat that enters the outer one does not enter the inner oneat all, passing away to the right by conduction through the outer sheet, asalready explained. To understand the effect of temperature-differences of this sort upon the. M»^tress, let us see wha
