Efficiency factors in natural gas fired steam boilers

In Figure 4, Boiler 2 has the lowest stack gas temperature and Boiler 7 has the highest value. When they are compared, a temperature difference of approximately 70°C is observed. By assuming a 1% decrease in efficiency for every 20°C increase in stack gas temperature, in Boiler 7 an efficiency decrease of nearly 3.5% is calculated.
