Burners and overfire air (OFA) - Babcock & Wilcox

B&W engineers designed the AireJet burner with an innovative burner structure — a burner built around a center jet of air, encircled by the fuel stream, and then wrapped in additional combustion air. Pulverized coal-fired boiler applications; Much cleaner burning so it requires less excess air to minimize carbon monoxide (CO) and unburned carbon

The winter choke: Coal-Fired heating, air pollution, and

·

China’s coal-fired winter heating systems generate large amounts of hazardous emissions that significantly deteriorate air quality. Exploiting regression discontinuity designs based on the exact starting dates of winter heating across different cities, we estimate the contemporaneous impact of winter heating on air pollution and health.

calculation of the excess air of combustion process

Calculation of the Excess Air of Combustion Process

Apr 16, 2018· Determining the amount of excess air in the boiler burning process depends on several main factors such as fuel type, boiler design, burner design, and boiler load. Generally, coal fired boilers use excess air as much as 15% to 30%. For boilers with gas or petroleum as its fuel, requires less excess amount of water.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
