Boiler Efficiency Testing Objectives - IIT Bombay

The efficiency of the boiler depends on the ability of the burner to provide the proper air-to-fuel mixture throughout the firing range, day in and day out, without the need for complex set-up or adjustments. When it comes to choosing the burner insist on linkage-less technology or, alternatively, a simple linkage assembly with minimal hysteresis, as well as accessible burner design for true efficiency and real savings. The burner should also be able to provide suitable turndown and low excess air. Low excess air capability is one factor that will improve the boiler efficiency.
