File talk:Water tube boiler schematic.png

According to the scheme, the hot gas, produced by burning, first is used to boil the water, and only then - to superheat the steam. This does not seem to provide the best efficiency, because the temperature of exhaust gasses cannot be below the temperature of superhot steam. The efficient scheme should imply that the gas first is used to overheat the steam, and only then, to boil, and, perhaps, to warm the water. In such a way, the temperature of the exhaust gas could be lower (say, 400 kelvin instead of 600 kelvin), with corresponding increase of the efficiency. Could anybogy upload the scheme of the efficient boiler? Domitori (talk) 04:51, 26 September 2008 (UTC)
