in the conventional well known manner referring now to fig2 3 and 3 a details of an embodiment of a combustor or combustor basket 26 of the present invention are shown the basket includes a wall 27 having a plurality of openings 29 formed there through for defining an inlet 19 and a peripheral wall 17 defining a combustion region 15 the inlet wall 27 and optionally a portion 28 of the peripheral wall 17 of the combustor basket include a multiplicity of small openings 29 also referred to herein as nozzles or injectors a dimension of these openings is determined by the quenching diameter of the fuel air mixture at gas turbine operating conditions for a modern gas turbine engine burning a relatively lean mixture of hydrogen fuel equivalence ratio of less than 1 at high pressure ratios 2 3 mpa and high combustor inlet temperatures 325 525 u00b0 c and high velocity on the order of 100 m sec the quenching diameter is on the order of 3 mm u00b1 2 0 mm the required fuel air flow area for a hydrogen burning combustor of such a typical land based gas turbine engine used for a power generation application typically about 20 mw per basket for example is about 0 03 m 2 to meet these conditions requires about 36 mm 2 of total area for each nozzle to allow for spacing between nozzles this is about half the cross.
