  1. 1. Experimental study of single fuel jet combustion and high-cycle regenerative systems

    Författare :Simon Lille; KTH; []
    Nyckelord :combustion; preheated air; energy savings;

    Sammanfattning : High Temperature Air Combustion (HTAC) is a technique toreduce consumption of fuel and decrease NOxformation in furnaces. The main change that occursin the furnace chamber is that the flow pattern of flue gasesaltered resulting in a more uniform heat transfer andtemperature profile. LÄS MER
