The changes of flow rate and heating value of blast furnace gas (BFG) make the boiler operation more like art than science. In this paper the importance of operation and maintenance and the effect on the efficiency of boiler is discussed. For this we are considering a case study of a 16 TPH boiler capable of generating steam of 42Kg/Cm 2 and temperature 420±5 o C. A system for automatic closed-loop control of drum boiler heat load for combined joint and separate combustion of blast-furnace gas
