How Stealth Combustion Losses Lower Plant Efficiency. Part 2: The Solutions
Important process variables that affect unit efficiency were reviewed in Part 1 of this two-part report. Many of those process parameters were also identified as related to boiler air in-leakage. These stealthy combustion losses are difficult to identify or locate yet have a significant effect on boiler combustion efficiency. Keeping your plant operating at or near […]
