Lean Catalytic Combustion for Ultra-low Emissions at High Temperature in Gas-Turbine Burners

Abstract

Catalytic systems for methane combustion, with Rh and Pt in a BaZrO3-based perovskite, were synthesized at the University of L’Aquila and tested at close to industrial conditions at the KTH Energy Centre in Stockholm. Because of the resistance to high temperature of BaZrO3 (up to ∼2600 °C), such systems are suitable for resolving stability problems frequently encountered with high-temperature operations. Furthermore, these perovskites contain the noble metal in a high oxidation state, giving rise to very active compounds. They also result in ultra-low emissions, compatible with legislation in such places as southern California and Japan.

Combustion Analysis of an Aviation Compression Ignition Engine Burning Pentanol–Kerosene Blends under Different Injection Timings

“…In addition, automotive diesel technologies have improved significantly, enabling high power-to-weight ratios for aviation applications. The North Atlantic Treaty Organization (NATO) nations have established a single fuel concept (SFC) policy that unifies all petroleum fuels to a single kerosene (JP-8) for the military, and many researchers have applied JP-8 to conventional compression ignition engines. − Yet the literature on aviation internal combustion engines is significantly less than that on vehicular internal combustion engines in terms of combustion and emissions characteristics. − …”

Synthesis and luminescence study of BaZrO3:Eu3+ phosphor

“…Morphological investigations of BaZrO 3 :Eu 3þ were carried out by SEM. photoluminescence (PL) emission and excitation spectra were recorded at room temperature by use of a Shimadzu RF-5301 PC spectrofluorophotometer [7]. The excitation source was a Xenon lamp.…”
