Nitrogen-based alternative fuel: an environmentally friendly combustion approach
Abstract
We report here on a continuous combustion of a low carbon nitrogen-based alternative fuel. The investigated fuel, an aqueous solution of urea and ammonium nitrate, consists of common fertilizer commodities. This nonflammable, nontoxic and nonexplosive fuel underwent combustion at a pressure range of 1 to 25 MPa. The pressure was found to greatly affect pollutant levels in the effluent gas. Molecular nitrogen yield was 99.89% at 25 MPa, and the lowest NOx level was 128 mg MJā1, below the regulation standard for power generation. The alternative fuel described herein is an excellent gas generator, producing an environmentally friendly working fluid consisting of 73.0% H2O, 21.6% N2, and 5.4% CO2. This fuel has the potential to be a sustainable future renewable energy storage medium as well as an energy carrier.
