    What is a Boiler Economizer? (with pictures)

    May 17, 2020· A boiler economizer may be used to increase a boiler's operating efficiency. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented. The byproducts of combustion are still hot, often quite …

    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.

    Selective non-catalytic reduction involves the injection of a NOx reducing agent, such as ammonia or urea, into the boiler exhaust gases at a temperature of approximately 1400-1600°F. The ammonia or urea breaks down the NOx in the exhaust gases into water and atmospheric nitrogen. Selective non-catalytic reduction reduces NOx up to 70%.
