Heat Recovery Steam Generators (HRSGs), Part 3: Predicting

Heat Recovery Steam Generators (HRSGs), Part 3: Predicting Off-Design Performance. This is due to the fact that the economizer acts as a bigger heat sink at higher steam loads. Note that the gas flow through the HRSG is nearly the same at 60,000 lb/h as it is at 22,780 lb/h. Hence with the same gas flow, but with higher water low, the economizer is able to pull the gas temperature lower.

The tubes are arranged so that hot combustion gases flow through the tubes. As the hot gases flow through the tubes, they heat the water surrounding the tubes. The water is confined by the outer shell of boiler. To avoid the need for a thick outer shell fired tube boilers are used for lower pressure applications.

Why do waste heat boilers fail? - Porter McGuffie, Inc

Typically waste heat boilers (WHBs) fail due to three factors: excessive tempera- ture, excessive mass flux rate and exces- sive water-side fouling 1. Similar to the racing industry, the sulphur industry has increased temperatures and mass flux (process flow) rates to obtain greater unit capacity.
