Abstract:
A good mixing of fuel/oxygen is important for the non-premixed combustion in micro combustor, and the thermal performance of outer wall is of significant influence to the application of micro thermo photo- voltaic (MTPV) systems. The non-premixed hydrogen/air combustion has been carried out in a novel micro combustor, in addition, the mixing performance of hydrogen/oxygen, the combustion characteris- tics, working performance of micro combustors are also investigated. Results show that the mixing per- formance of hydrogen/oxygen can be improved by the adoption of four pipes in combustor, and the thermal performance of combustor affects flame velocity, reaction rate and combustion efficiency. Moreover, the cavity or backward-facing step contributes to the heat recirculation and the flame stabi- lization, and a high and uniform outer wall temperature distribution is desirable for the application of MTPV system, which can be obtained at the hydrogen volume flow rate 90 mL/min and the equivalence ratio 1.0
