The purpose of this study is to demonstrate the feasibility of hydrogen combustion with water spray using two-fluid nozzle. In the nozzle, water is atomized by the fuel, hydrogen. Therefore, the fuel and water are dispersed from the nozzle simultaneously. As a result, water is sprayed in hydrogen diffusion flame and evaporated. In addition, hydrogen is diluted by its vapor and thus, the reduction of NOx emission is expected due to temperature fall and slow combustion. This paper reports the demonstration of stoichiometry hydrogen combustion of 6.0kW heat release rate with water evaporation using two-fluid nozzle.
