Solution Overview
Problem
The setup time for mobile power generation systems, particularly gas turbine-based systems used in fracturing operations, is lengthy due to the complexity and time required to transport and set up the necessary components, which hampers efficiency at fracturing sites.
Innovation Solution
A mobile power generation system is designed with a trailer housing a gas turbine and electrical generator, equipped with an exhaust silencer system and noise attenuation assembly, featuring a diffuser system, baffles, and acoustical insulation to reduce noise and enhance efficiency, allowing for quicker deployment and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a gas turbine-based mobile power generation system is used to provide electrical power for fracturing operations, then power generation capability is improved, but setup time increases
Solution Approach 1:
The patent combines the gas turbine, electrical generator, exhaust silencer system, and noise attenuation assembly into a single integrated mobile power generation system housed on a trailer. This merging of multiple components into one unified system allows for quicker deployment as a complete package rather than assembling separate components at the site, thereby reducing setup time while maintaining full power generation capability.
Solution Approach 2:
The system is pre-assembled and pre-configured on a trailer before deployment to the fracturing operation site. All major components including the gas turbine, generator, and noise attenuation systems are installed and prepared in advance, eliminating the need for time-consuming on-site assembly and reducing setup time while preserving full operational capability.
2Object-affected harmful factors
If an exhaust silencer system with noise attenuation assembly is added to reduce noise, then noise levels decrease, but device complexity increases
Solution Approach 1:
The noise attenuation assembly is nested within or integrated with the exhaust silencer system structure. The assembly includes multiple components (baffles, acoustical insulation materials, housing) that are arranged in a nested configuration where inner components are contained within outer structures, achieving effective noise reduction while maintaining a compact and relatively simple overall system design.
Solution Approach 2:
The noise attenuation assembly utilizes composite construction combining different materials such as acoustical insulation materials, baffles, and housing structures work together to reduce noise. This composite approach achieves effective noise attenuation through material properties rather than requiring complex mechanical arrangements, thereby reducing system complexity while maintaining noise control effectiveness.
