Abstract: This disclosure relates to systems and methods of predicting physical parameters for a combustion fuel system. In one embodiment of the disclosure, a method of predicting physical parameters of a combustion fuel system includes causing water injection in at least one combustor. The water injection is associated with at least one time and performed during gaseous fuel operations or after liquid fuel operations. The method includes measuring exhaust spread data associated with the water injection and allows correlating the exhaust spread data to at least one physical parameter associated with a nozzle or a valve of the fuel system. The method further includes storing the exhaust spread data, the at least one physical parameter, and the at least one time to a database. The method further provides stored historical data from the database to an analytical model. The analytical model is operable to predict, based at least partially on the stored historical data, at least one future physical parameter associated with a future time.

Abstract: A silencer apparatus for a gas turbine inlet system ducting is disclosed. The inlet ducting contains a main silencer and a pre-silencer, and Inlet Bleed Heat (“IBH”) located between the silencers. The pre-silencer decreases the noise level from the turbine compressor and makes the air flow/temperature profiles more uniform. The main silencer reduces noise from the IBH and the remaining noise from the compressor to an appropriate level. The main silencer is comprised of a first plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting. The pre-silencer is comprised of a second plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting, but staggered with respect to the first plurality of splitters to thereby block a direct line of travel for noise acoustical waves from the compressor travelling opposite the gas flow direction in the inlet ducting.
Abstract translation: 公开了一种用于燃气轮机入口系统管道的消声器装置。 入口管道包含一个主消音器和一个预消声器，以及位于消音器之间的入口泄放热（“IBH”）。 预消声器降低了来自涡轮压缩机的噪音水平，使气流/温度曲线更加均匀。 主消声器将IBH的噪音和压缩机的噪音降低到适当的水平。 主消声器包括沿燃气轮机入口管道中的气流方向设置的第一组多个吸声分离器。 预消音器由在气体涡轮机入口管道中沿着气体流动方向设置的第二多个吸声分离器组成，但是相对于第一多个分离器交错，从而阻挡用于噪声声波的直线行进 从压缩机在入口管道中与气体流动方向相反地行进。
