| Research Abstract |
By using continuously varying multi-step combustion and self recirculation of burned gas, an attempt has been made to realize a ultra, low NOx burner. To achieve this goal, a burner, which adopts a new element, tubular flame, is used, and a spatially distributed fuel concentration field is made by varying the fuel to air injection velocity ratio, and in addition, a recirculating flow of hot burned gas is induced by using an ejector effect of a gas mixture which is tangentially injected into the tube with a high velocity.As a result, the NOx emission is reduced to 10 ppm at the air/fuel ratio 1.4 for methanewith this simple structure burner.
