Few parameters critical to health of the Boiler are:
(1)Heat rate of the Boiler. This is a composite index of many performance indicators. Most of them will appear below.
(2)Unburnt fuel in flue gas and at boiler bottom .
(3)Flue gas furnace exit temperature.
(4)Boiler tube metal temperatures.
(5)Oxygen in flue gas.
(6)Imbalances in flue gas temperature over a cross section.
(7)Spray water consumption in Super heater and Reheater.
(8)Heat radiation from insulation.
The above all affects the performance of the boiler.
