6/6/2009 · The major portion of carbon loss in a boiler is from unburned carbon in fly ash. A method was developed by me after a large volume of data was subjected to analysis and validation. It is seen from the analysis and literatures that the fuel ratio i.e. the ratio of fixed carbon and volatile matter in coal has a very significant effect.

Unburned carbon from coal combustion ash: An overview - …

1/6/2015 · Vast quantities of ash are produced in coal combustion power stations annually. Including aluminosilicate matrix, all ashes also contain unburned carbon (UC) of varying amounts; in some ashes it can exceed 10% (or even 45% in stoker boilers). High UC levels in ash does not only constitute an energy loss during combustion, it can also hinder

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

Unburned carbon from coal combustion ash: An overview - …

Abstract: The unburned carbon loss in fly ash of circulating fluidized bed (CFB) boilers, most of which are burning active fuels such as lignite or peat, is norrrally very low. However, most CFB boilers in China usually burn hard coals such as anthracite and bituml nous coal and coal wastes, so the carbon content in the fly ash from these boilers is higher than expected.

6/6/2009 · Carbon loss in boiler reduces the boiler efficiency, and if the coal is high ash as well as low reactive this can be a substantial portion. The existence of unburned carbon in ash decreases not only the combustion efficiency but also the grade of fly ash for commercial sale. Predicting percentage combustibles in fly ash in a tangential fired boiler using proximate analysis of coal gives boiler
