### Boiler Efficiency | How to balance steam loads efficiently

Aug 26, 2011 · Steam generator performance. The first step is to understand the load-versus-efficiency characteristics of a typical package boiler. Table 1 shows performance variation as a function of load. The boiler with an economizer generates 100,000 lb/h of saturated steam at 400 psig using natural gas. At 100% load, the exit gas temperature is 320 °F.
