relationship between pressure and stack temperature for a test on a 65,000 lb/hr watertube boiler operating at a constant output of 38,500 lb/hr. As tested, the boiler stack temperature varies linearly with steam pressure. A savings of 0.4% to 0.8% of the fuel input can be expected from lower stack temperature.
