Calculating Boiler Efficiency

This method calculates boiler efficiency by using the basic efficiency formula- η=(Energy output)/(Energy input) X 100 In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred.

Boiler thickness and pressure | Model Engineer

I have some tube, 0.043" wall thickness, nominally 2.625 diameter I bought as 'boiler tube', without a specific project in mind. Tubal Cain's formula gives a working pressure of well over 100psi (it gives 124psi if you use 3800 as the 'working stress' at 100psi)/350fahrenheit), which seemed very high to me.
