Economisers - Byworth Boilers

The typical temperature of flue gases flowing from the final pass of tubes from a 3 pass wetback 150 psi steam boiler would be 240 degrees C. This heat is then lost up the chimney to the atmosphere but some of it could be recovered utilising a flue gas economiser and used to pre-heat the boiler feed water.
