NO and N2O formation during the combustion of wood, straw, malt waste and peat
Abstract The NO and N 2 O formation behavior of six biofuels (spruce wood, beech wood, alder wood, straw, malt waste, peat) was studied in a formation-rate unit under conditions relevant to aExpand

The NO and N2O formation mechanism during devolatilization and char combustion under fluidized-bed conditions
In an exclusively electrically heated, laboratory-scale, fluidized-bed compustor (MM-FBC) made of quartz glass, the formation rates of NO, N 2 O, and HCN are studied by using a high performance FT-IRExpand

Demonstration of methane spectroscopy using a vertical-cavity surface-emitting laser at 1.68 µm with up to 5 MHz repetition rate
An electrically pumped InP-based vertical-cavity surface-emitting laser (VCSEL) emitting at 1.685 µm (5935 cm−1) was used to probe rovibrational transitions of methane in the 2ν3 band at pressuresExpand

Reducing Ability of CO and H2 of Gases Formed in the Lower Part of the Blast Furnace by Gas and Oil Injection
Gases formed in the raceway by injection of reducing agents into the tuyere affect the blast furnace process in several ways. Energy set free by conversion in the raceway helps the melting of theExpand
