Gas accumulation detection and ventilation in a gas turbine enclosure

A gas accumulation detection and ventilation system for a gas turbine enclosure, the gas accumulation detection and ventilation system comprising:

• a pipe array positioned adjacent a floor of the gas turbine enclosure, the pipe array including a plurality of pipes, each of the plurality of pipes having a plurality of inlet openings therein;
• a suction device coupled with the pipe array, the suction device being configured to draw a vacuum on the pipe array and to siphon an environmental sample from the gas turbine enclosure via the pipe array;
• a ventilation assembly including a fan and air flow outlet and an air flow inlet, wherein the fan is configured to direct an air flow sweep through the air flow inlet along the floor of the gas turbine enclosure;
• and
• a hazardous gas sensor panel in communication with the pipe array and the ventilation assembly, the hazardous gas sensor panel being configured to detect an accumulation level of turbine fuel gas in the gas turbine enclosure based on input from the pipe array and to activate the ventilation assembly when the accumulation level exceeds a predetermined threshold.

A method of detecting and ventilating a gas turbine enclosure, the method comprising:

• (a) positioning a pipe array adjacent a floor of the gas turbine enclosure, the pipe array including a plurality of pipes, each of the plurality of pipes having a plurality of inlet openings therein;
• (b) drawing a vacuum on the pipe array and siphoning an environmental sample from the gas turbine enclosure via the pipe array;
• (c) detecting an accumulation level of turbine fuel gas in the gas turbine enclosure based on input from the pipe array in step (b);
• and
• (d) when the accumulation level detected in step (c) exceeds a predetermined threshold, activating a ventilation assembly according to the accumulation level by directing an air flow sweep along the floor of the gas turbine enclosure.
