Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turbine engine components, such as compressor and turbine blades, suffer from performance degradation due to impurities like salt, oil, and combustion residues, and are vulnerable to fire hazards during fracturing operations, requiring effective cleaning and protection systems.
Innovation Solution
A turbine engine cleaning system comprising a temperature sensor, cleaning agent storage, and a delivery device with a pipe and driver mechanism, along with a fire-control subsystem for hazard protection, which includes sensors, storage units, and flow-control units to manage cleaning agents and fire-control substances based on temperature, pressure, and hazard detection.

Engineering Contradiction Analysis
1Productivity
If cleaning agent is delivered into the combustion chamber, then cleaning effect is improved, but temperature-related damage may occur
Solution Approach 1:
The temperature sensor detects the temperature within the combustion chamber before cleaning agent delivery is initiated. The system waits for the temperature to drop below the predetermined threshold, then activates the driver mechanism to deliver the cleaning agent. This preliminary temperature check ensures the combustion chamber is cool enough to prevent thermal damage to cleaning agents and engine components.
Solution Approach 2:
The control unit continuously receives temperature information from the temperature sensor and adjusts the cleaning operation accordingly. When the temperature exceeds the predetermined value, the control unit prevents cleaning agent delivery. When the temperature drops below the threshold, the control unit enables the driver mechanism to deliver the cleaning agent. This feedback loop ensures cleaning only occurs under safe temperature conditions.
2Reliability
If fire-control substance is delivered to protect from hazards, then protection effectiveness is improved, but false activation may occur
Solution Approach 1:
The flame detector detects the presence of flame through optical detection, likely utilizing changes in light emission characteristics. When flame is detected, the control unit activates the fire-control substance delivery system. This optical detection method provides reliable distinction between actual fire hazards and normal operating conditions, reducing false activation while ensuring effective protection when needed.

AI summary
A fracturing system is disclosed. The fracturing may include a turbine engine; a fracturing fluid pump powered by the turbine engine via at least one reduction gearbox; an auxiliary mover for powering a hydraulic system for lubricating the turbine engine or the fracturing fluid pump or for powering a cooling system for cooling the turbine engine or the fracturing fluid pump; a first fire-control subsystem associated with the turbine engine; and a second fire-control subsystem associated with the auxiliary mover. The fracturing system is thus configured to provide fire-control and fire-fighting capabilities to minimize inadvertent consequences to the turbine engine as well as the auxiliary mover.
