The circulation ratios of 1. Natural circulation industrial boiler - 10 to 15 2. Natural circulation utility boiler - 7 to 9 3. Assisted circulation boilers - 2 to 4 4. Forced circulation / once through boiler - 1 Q What are the boiler mountings. A.

It is the operating range of boiler from maximum capacity to minimum capacity in which the boiler can run efficiently without any external fuel support . The higher turn down ratio greater the efficiency of boiler. For example if the boiler is designed 80mw and can operate up to 20mw without any external fuel support and any variations of parameter then the turn down ratio is 80/20=4. Q. What is boiler efficiency. A. It is the ratio of heat output to heat input of the boiler. Boiler efficiency= Heat output / hea
