Scaled Water Tube Boiler Efficiency
Scaled Water Tube Boiler Efficiency
(OP)
Are there any rules of thumb on how much efficiency drops from scaled tubes? For example, let's say that you have a uniform 1/8" thick scaling on all tubes. What can we say about the efficiency?
Also, just a general question on efficiency of B&W boilers. I have an old unit operating at 90 psig. Burner efficiency has 80% rating, but how can I estimate the overall efficiency (gas to steam)? There is no economizer.
