Introduction

This manual describes the Woodward Swift™ Gas Metering System for

micro/mini-turbines, small industrial turbines, and high-pressure fuel cell

applications. This manual provides installation instructions, product description,

troubleshooting, and specifications. This manual does not contain instructions for

the operation of the complete prime mover system. For prime mover or plant

Applications

The Woodward Swift gas metering system operates on micro/mini-turbines, and

small industrial turbines ranging from 30 to 2000 kW, as well as high-pressure

fuel cells (> 97 kPa/14 psig) up to 3000 kW. The Swift system has four valve

sizes with maximum fuel flows of 6 to 88 g/s (50 to 695 lb/hr) of standard natural

gas, depending on the system pressures (see Table 1-1). The system is

designed for installation in the prime mover enclosure and can accommodate gas

temperatures up to 121 °C (250 °F).
