Emissions from steam generator

[sfcnsb]

I'm planning on running a 32MMBTU/hr steam generator and fire it with diesel. I'm looking for some help on determining the emissions (ie. Nox, Sox). We can assume 85% combustion effeciency and 3% excess O2. Can anyone help me on this question.

Best Regards

Sox is a function of the sulfur content of your fuel oil, so only you can answer that, and Nox is to a large extent a function of your firing temperatures (among other things) so, again, we can't offer any suggestions without lots more information from you.

I don't know which country you are in, but here in Canada you can refer to CCME (Canadian Council of Ministers of the Environment)Guidelines. These guidelines provide max allowables based on the duty of your boiler. I also believe they provide examples of how to calculate your emissions as well.

The U.S. EPA (Environmental Protection Agency) publication "AP-42, Compilation of Emission Factors" has the information you want. The publication is available online.

Go to Volume I, "Stationary Point and Area Sources" which is available at www.epa.gov/ttn/chief/ap42/index.html and then to Chapter 1: "External Combustion Sources", and then to Section 1.3: "Fuel Oil Combustion", and then to Final Section: "Supplement E".

In Supplement E, start reading and scrolling ... and you will eventually find tables listing the many various emission factors for burning diesel oil. If your boiler is in the U.S., your local air pollution regulatory agency will most probably be be using the EPA's AP-42 emission factors.
