increasing trend has created a need for utilities to evaluate the effect of changing coal supplies on the performance of the existing boiler and firing system components. In the early 1990’s the fleet of coal-fired boilers underwent the first of many changes to regulate the NOx emissions emitted from the boiler.

Coal Quality Boiler Efficiency - Fossil Fu

Coal Quality Boiler Efficiency. Coal Quality & Boiler Efficiency. Introduction. • Kelvin Power currently consists only of the B-Station plant which is fitted with seven 60MW units. • On the north side of B-Station, four Babcock/Wilcox PF boilers generate steam for four GEC turbine generators. – The Babcock/Wilcox boilers are fitted with four Babcock E56 vertical spindle mils each.


1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.

How to Run a Coal Fired Boiler at the Best Efficien

Keep an optimal excess air level, generally about 20% in a coal fired boiler; Tune combustion of coal to the optimal condition. Understand the coal being fired; Proper distribution of combustion air at primary, secondary, and tertiary levels; Keep the required fineness of coal about 75% through 200 mesh and less than 2% on 50 mesh sieve

Coal-Fired Power Plant Heat Rate Improvement Options, Part

At the same time, in some areas, decreasing coal quality and the use of higher-moisture-containing fuels such as Powder River Basin coal contributed to a reduction in unit performance.


The most accepted method of measuring boiler efficiency is the "heat loss" method. Most Eastern Bituminous coal fired utility boilers are capable of around efficiency. It should be pointed out that 90% boiler efficiency can be maintained — yet unit heat rate penalties experienced at that given time may represent more than — or about 200 BTU/KwHr.
