Catalytic combustion of hydrogen; Vedyn katalyyttinen palaminen

Abstract

Hydrogen catalytic combustors are advantageous because they release heat at lower temperatures than flame combustors. Low operation temperature and flameless burning make the process safe. The combustion temperature can be controlled continuously by changing the hydrogen flow rate. Combustion gas of hydrogen catalytic combustor is water vapour, and if burned with air certain amounts of nitrogen oxides may also occur. Commercial applications are nowadays gas monitors for combustible gases. Applications of hydrogen catalytic combustion are predicted to increase in households heaters, cooking devices and industrial drying and heating processes. Further research of hydrogen catalytic combustors is concentrated on increasing their power and reliability in running. The literature review of this report describes catalytic combustion and especially hydrogen catalytic combustion. The construction of hydrogen catalytic combustor and different catalytic materials are explained. Some examples of commercial or near commercial applications are shown. An experimental construction was built to tentative run an open catalytic combustor, 50 W. The maximum operation temperature 164 deg C was reached with hydrogen flow rate 15 l/h. The temperature was easily controlled by changing hydrogen flow rate. The combustion efficiency reached in these tests was 95 %.
