Fly ash - Wikipedia

Fly ash or flue ash, coal ash, and also known as pulverised fuel ash in the United Kingdom, or coal combustion residuals (CCRs), is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases..

1/11/2006 · Based on a 20-year breakeven consideration, assumed capacity factor of 80% and coal cost of $1.42/GJ. ($1.50/M BTU), EPRI has estimated that an USC plant can be cost competitive even if the total plant capital cost is 12%–15% more than a comparable scale facility built using conventional subcritical boiler and cycle designs, due to the fuel cost savings over the 20 year period.

Steam Calculators: Boiler Calculator

17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
