    How to Run a Coal Fired Boiler at the Best Efficiency

    Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

    Pulverized Coal Boiler - an overview | ScienceDirect Topics

    A typical pulverized coal boiler consists of (1) the furnace, which is the lower boiler part, where the burners and the firing system are installed and where the combustion takes place and (2) the convective section, where the convective heat exchanger surfaces are installed. The boiler membrane walls have usually the function of the boiler evaporator.

    Increased carbon burnout is important for both increased boiler efficiency and enhancing the value of the fly ash (Yu et al., 2005). The amount of coarse (>100 mesh, 150 μm) material in a pulverized coal has negative impacts on both the carbon burnout (efficiency of carbon combustion) and on the efficiency of NO x reduction (Maier et al., 1994).

    Pulverized Coal Fired Steam Boilers | Coal Fired Boilers

    Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels.

    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
