摘要：
The porous burner technology is a modern way of energy conversion with a strong potential to achieve high efficiency. marginal pollutant emissions and low fuel Consumption. For it better understanding of the combustion process inside this complex system, accurate measurements of different key parameters are required. In this paper we present to the best Of Our knowledge the first non-intrusive spatially resolved gas-phase temperature and H-2 concentration measurements taken inside such a porous burner. This is achieved by means of dual-pump vibrational coherent anti-Stokes Raman scattering (CARS) at operating conditions of phi = 1 and 1 kW thermal power. Furthermore the combustion of a premixed methane/air mixture (equivalence ratio phi = 0.9) has been studied experimentally at thermal powers of 1, 1.5 and 2.5 kW. Due to the strong heat transfer front the gas-phase to the porous solid structure, the maximum gas temperatures are significantly below calculated adiabatic flame temperatures. The temperature gradient in the medium was found to be small compared to conventional premixed flames. (C) 2009 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
