Sep 06, 2001 · At this turndown ratio and efficiency, the input will be 1,338,000 Btu/hr. For a gas fired boiler, the energy input is 1,000,000 Btu per mcf of gas. The boiler in Table 1 will use 1.338 mcf/hr to generate 30 bhp, the minimum operating level. Since only 10 bhp is needed, 20 bhp of steam goes up the stack as wasted energy.

Efficiency factors in natural gas fired steam boilers

The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas …
