Boiler Efficiency | How to balance steam loads efficiently

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 load, the exit gas temperature is 320 °F. Excess air is 15%.

This envelope is-based on the criterion that average diametral sheath strains, measured at the pellet mid-plane positions, should not exceed 0.4 %. The algorithm for calculating strains is based on normalisation of measured strains, to allow for the effects of fuel density, power and bumup.
