This study tried to apply biomass fuel to burner combustion at high load. Water was used independent of emulsification to reduce toxic emission. A new injector was first developed. The injector mixes fuel rapidly with water inside of the injector with support of atomizing air. The mixture composed of three-fluid is injected as spray into a flame stabilizer of burner. Gas oil, soybean oil and water-emulsified soybean oil were used as fuel. The controllable parameters in the experiment were fuel type, flow rate of fuel, atomizing air, secondary air and water. The concentrations of NOx, CO, CO_2 and PM were measured. Investigation of emission performance of this injector shows that the internally rapid mixing type of injector is useful technique to introduce water into burner combustion. The injector emits exceedingly less particulate matters at high load. NOx is reduced with the use of water. NOx emission is strongly dependent on water flow rate.
