combustion chambers and reactors

Combustion chambers and reactors

For   research   purposes,   I-TPT   supplies   tailor-made   combustion   chambers   and   reactors including    the    associated    control    technology.    One    focus    here    is    on    combustion    test benches   that   can   be   operated   at   temperatures   of   up   to   2200   °C   and   high   pressure.   The systems    allow,    for    example,    the    laser-optical    investigation    of    combustion    processes, material    tests    under    extreme    conditions    or    the    provision    of    hot    gas    with    defined properties.

Burner test rig

The   joint   burner   test   bench   of   the   Institute   for   Turbomachinery   and   Fluid   Dynamics   and the   Institute   for   Technical   Combustion   of   the   Leibniz   University   Hannover   has   been equipped    with    a    new    test    combustion    chamber    in    order    to    be    able    to    carry    out combustion   tests   and   also   to   enable   the   application   of   new   measurement   techniques. The   burner   test   bench   is   used   to   carry   out   extensive   tests   on   flames   and   exhaust   gas jets.  In   order   to   allow   a   high   variability   of   the   burner   test   bench,   the   combustion   chamber   has a   modular   design.   It   is   composed   of   individual   main   segments,   which   can   be   exchanged with   each   other,   so   that   the   measuring   technique   can   be   applied   at   different   places.   The burner   test   bench   is   used   within   the   framework   of   the   Collaborative   Research   Centre 871: Regeneration of Complex Capital Goods.

High pressure porous burner

In   a   collaboration   between   the   Chair   of   Fluid   Mechanics   at   the   University   of   Erlangen Nuremberg   and   Evonik   Industries AG,   a   high-pressure   burner   was   developed   that   is   used for   gas-dynamically   initiated   particle   production   (GIP).      The   highlight   of   the   high-pressure burner   is   the   stabilization   of   the   combustion   reactions   in   a   ceramic   foam.   This   enables stable   combustion   over   a   wide   power   modulation   range   at   pressures   between   1   bar   and 10   bar.   The   test   bench   also   allows   an   exact   adjustment   of   the   gas   temperature   and   the oxygen concentration, which is decisive for the downstream GIP reactor. 

Combustion chamber for laser-optical investigation of the

mixing behaviour of hot gasesT

The   combustion   chamber   is   heated   by   a   modulating   burner   (diesel)   and   can   be   operated at   pressures   of   up   to   10   bar   and   gas   temperatures   of   up   to   500   °C.   The   combustion chamber   is   surrounded   by   cooling   air.   The   combustion   chamber   is   surrounded   by   cooling air,   which   is   mixed   with   hot   exhaust   gas   downstream   of   the   combustion   chamber.   This prevents    the    resulting    hot    exhaust    gas    from    coming    into    direct    contact    with    the combustion   chamber   wall.   12   integrated   sight   glasses   with   a   clear   width   of   150   mm   each allow   good   optical   access.   The   individual   modules   can   be   exchanged   at   will   so   that measurements can be taken at almost any point along the combustion chamber axis.
