An Investigation of the Effect of Input Air Upon Combustion Performance and Emissions of Biodiesel and Diesel Fuel in an Experimental Boiler

Abstract

This article addresses effect of input air upon combustion performance and environmental pollution of biodiesel and diesel in a semi industrial boiler. The thermal capacity and exhaust temperature as the combustion performance and emissions like CO₂, SO₂, CO, and NO_x are investigated and plotted over a wide input air to the boiler at a constant fuel pressure of 160 psi and diffuser setting at 3 mm. Indeed, this article demonstrates, in a non-premixed combustion of biodiesel and diesel, how performance of a boiler changes with increasing and decreasing of input air to the boiler. Afterwards, the trend of emissions with change in the input air will be depicted as well.
