用于燃气涡轮的自动化燃料混合和控制的系统和方法
摘要：
本发明涉及用于燃气涡轮的自动化燃料混合和控制的系统和方法。具体而言，本发明为干式低NOX燃气涡轮(200)的运行提供了一种将低廉的辅助气体(320)与主要气体燃料(305)混合的灵活且自动的系统和方法。辅助气体(320)可以是气体燃料，例如氢气、乙烷、丁烷、丙烷以及液化天然气或惰性气体。通过将混合燃料(355)控制在修正沃泊指数的可允许的范围内，可避免燃烧动力。还可监测燃烧动力(375)和燃气涡轮排气排放(370)，以保持使用混合燃料(355)的安全燃烧。燃气涡轮控制系统(290)可调整主要气体燃料(305)和辅助气体(320)的混合物(355)和温度(361)，以促进所需的燃烧。
摘要（英）：

The present invention relates to a system and a method for automatic fuel bending and control for combustion gas turbine. Concretely, the present invention provides a flexible and automatic system and method for blending an inexpensive secondary gas (320) with a primary gas fuel (305) for operation of a Dry Low NOx gas turbine (200). The secondary gas (320) may be a gas fuel such as hydrogen, ethane, butane, propane and liquefied natural gas or an inert gas. Combustion dynamics are avoided by controlling the blended fuel (355) within a permissible range for a Modified Wobbe Index. Combustion dynamics (375) and gas turbine exhaust emissions (370) may also be monitored to maintain safe combustion with the blended fuel (355). A gas turbine control system (290) may adjust the blend (355) and temperature (361) of the primary gas fuel (305) and the secondary gas (320) to promote desired combustion.
