Real-time Monitoring of Unburned Carbon-in-Ash from

Cited by: 195: Dr V T Sathyanathan2004-8-5 · Coal fired boilers have various sources of thermal energy loss. The main sources are the dry gas loss as well as the loss-on-ignition (LOI) of the ash leaving the boiler. The vast majority of the combustible portion of the ash that accounts for the energy loss is

High Flyash LOI’s - Innovative Combusti

High Flyash LOI’s At the current time, operating coal fired boilers with the lowest possible emissions of Nitrous Oxides are imperative. Proper sizing of coal transported through the burner lines is mandatory to achieve low NOx formation without unacceptable levels of unburned carbon in flyash.

Combustion modifications for NOx control in coal-fired boilers can increase the unburned carbon (UBC) in the ash, as measured by an increase in loss-on-ignition (LOI) in the ash. Increases in LOI reduce combustion efficiency and can have negative impact on electrostatic precipitator (ESP) performance and sale of the fly ash.

Dew point of flue gases as related to corrosion of

Whenever fossil fuels containing sulfur are fired in heater or boilers, sulfur dioxide, and to a small extent sulfur trioxide, are formed in addition to CO/sub 2/ and water vapor. The SO/sub 3/ combines with water vapor in the flue gas to form sulfuric acid and condenses on heat transfer surfaces, which could lead to corrosion and destruction

How to Run a Coal Fired Boiler at the Best Efficienc

Cited by: 122020-5-8 · Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
