Prediction of SOx–NOx emission from a coal-fired CFB power

The circulating fluidized bed boiler is an advanced clean energy technology that has received much attention in the power industry due to its fuel flexibility. In this study, a deep neural network with a modified early stopping algorithm and least square support vector machine were developed to predict SOx and NOx emissions associated with coal

What happens when limestone is fed in a coal-fired boiler

It depends on the type of coal-fired boiler. If it’s a Bubbling Fluidised Bed (BFB) or Circulating Fluidised Bed (CFB) boiler then limestone could be added to the bed material to give a de-sulphurising effect.

However, our CFB boiler is single-drum, high-temperature cyclone separator structure. The furnace, separator, and tail shaft are independent, ensuring high combustion efficiency and solving the sealing problem. The membrane wall is designed to ensure that the coal and limestone can be uniformly combined in the furnace.

David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.

Jun 02, 2014· In CFB boiler limestone addition in the furnace reduces the Sulphur Dioxide during combustion itself. This requires only a simple limestone storage and handling unit. In PC boilers around 15 % of ash collects at the bottom of the furnace and the balance in the electrostatic precipitators.
