By making use of software CHD FLUENT and chemical reaction dynamics software DETCHEM a numerical simulation was conducted of the catalytic combustion of a mixture of CH_4 and air in a micro-burner featuring counter-flow heat exchange.

In this paper was preformed numerical simulation of catalytic combustion of CH4 for micro-burner with counterflow heat exchanger using both FLUENT and surface chemistry subroutine DETCHEM.

Considering that micro combustors are easy to flameout, low efficiency and problems of coke deposition and micro flow.

In order to improve the combustion property in the micro combustor,the problems in the micro combustor are analyzed and the relevant measures are put forward.

This paper is a continued report of our p re vious publication "design and fabrication of a silicon-based micro combustor f or micro gas turbine engine".

Numerical Simulation on Premixed Catalytic Combustion of Methane in Micro-combustor;

Numerical investigation of premixed catalytic combustion of methane in micro-combustor

Combustion in a micro-combustor is a complex physical and chemical phenomena.

Aiming at the ignition and stabilizing combustion problem of low volatile coal,the constitution of ignition and combustion stability system and structure of burner with tiny-oil in abundant oxygen were introduced,and the principle of ignition and combustion stability was analyzed.
