Inlet Guide Vane System


inlet-guide-vane-turboexpanderThe purpose of the inlet guide vane system is to direct gas-flow toward the expander wheel at the correct angle while also providing control of mass flow through the turbine. This is a key feature of an L.A. Turbine turboexpander and is therefore a focus of engineering attention. Pressure, temperatures, gas composition, material, and clamping forces are all considered to eliminate blow-by and allow the turbine to operate reliably for extended periods. To accommodate varying operating conditions, the inlet guide vane system is designed to open beyond the design point to allow for start-up or emergency situations. L.A. Turbine specifies quiet, highly reliable, and fast-acting actuators for use with inlet guide vane systems.
