Our recuperators are usually designed for dirty or difficult applications, often resulting from high temperature flue gas (up to 1600°C) or from flue gas contaminated with high levels of dust (as found in the glass or metals industries). We also provide units with burners, firing natural gas, syngas, biomass and waste fuels (via fluid bed combustors/gasifiers).
Our recuperator range of products includes, radiation cage, radiation shell, convective flue tube as well as convective channel type depending on the gas temperature and fouling propensity.
Recuperators usually heat combustion air to make the process more efficient, however they may also be used for heating gaseous fuels such as natural gas or heating process gas such as nitrogen, oxygen or steam. We have experience of heating these to 900°C.
