B. 2005-2006 SoCalGas Equipment Tests

SoCalGas continues to fill the data gaps on equipment performance utilizing changing gas quality. The 2005-06 testing included testing equipment not previously tested, the addition of different makes and models of equipment already tested and expanded testing of low NOx boilers with fixed air fuel combustion systems that displayed NOx emission sensitivity to changes in Wobbe Number.
