Hurst steam boilers+pneumatics
I have one question: It's normal for a commercial steam boiler to have a pneumatic relay on the side to fire the burner (When a pneumatic control system is used) But every time the unit fires, there is a deafening release of air from the relay. We think the backlash involved is destroying the delicate the electrical contacts inside. This has happened at least 10 times this season so far, and is getting costly. (The relay has been replaced once, and it's insides replaced at least 5 times) It's an odd problem, any ideas?
Thanks in advance, the other pneumatic control air threads were of no help.
