Abstract
A mobile fracking system and methods may include a gas turbine housed at least partially inside a trailer and an exhaust attenuation system configured to receive exhaust gas from the gas turbine. The exhaust attenuation system may include a lower elongated plenum configured to receive exhaust gas from the gas turbine and an upper noise attenuation system that is movably connected relative to a distal end of the lower elongated plenum.
Claims26
A mobile fracking system comprising:
- a trailer;
- a gas turbine engine connected to the trailer;
- and
- an exhaust attenuation assembly configured to receive exhaust gas from the gas turbine engine, the exhaust attenuation assembly connected to a portion of the trailer, the exhaust attenuation assembly comprising:
- a first elongated plenum having a proximal end and a distal end, the first elongated plenum extending a first distance between the proximal end and the distal end and defining an inlet adjacent the proximal end positioned to receive exhaust gas from the gas turbine engine;
- and
- a noise attenuation system movably connected relative to the distal end of first the elongated plenum, the noise attenuation system comprising:
- a first silencer hood hingedly connected to a first side of the distal end of the first elongated plenum to pivot relative to the first elongated plenum;
- and
- a second silencer hood hingedly connected to a second side of the distal end of the first elongated plenum to pivot relative to the first elongated plenum, the first silencer hood and the second silencer hood being positioned and movable such that:
- in a first position, the first silencer hood and the second silencer hood form a second elongated plenum positioned to receive the exhaust gas from the first elongated plenum, and
- in a second position, the first silencer hood and the second silencer hood are in a stowed position for transport.
