OBJECTIVES
Qualifying a steam suction tool for the nuclear sector by ensuring compliance with the operating conditions defined by the client. Specifically, in terms of flow rate, pressure, and passage speed, thanks to a controlled and regulated steam solution.
CLIENT REQUEST
As part of a project to qualify a steam suction tool for the nuclear sector, the client was looking for an installation that could faithfully reproduce the conditions defined in its specifications.
The main expectations were:
-
- Steam flow rate of 0.250 t/h
- Operating pressure of 8 bar
- Compliance with passage speeds
- Equipment qualification in complete safety
CHALLENGE
Providing steam production capable of maintaining a low flow rate with very precise regulation, while meeting the technical requirements of the nuclear sector as well as the constraints of a site located in a marine environment.
TIBBLOC SOLUTION
Tibbloc installed an electric steam boiler on its site equipped with a pressure reduction system and instantaneous flow control.
The installation also included:
- an electric steam boiler,
- a generator set,
- a 5,000 L fuel tank,
- a control system to limit steam losses
PROFITS
- Qualification compliant with specifications
- Precise flow and pressure regulation
- Minimization of steam losses
- Complete ready-to-use solution
- Testing performed at the Tibbloc facility
- Technical support dedicated to the nuclear sector
OBJECTIVES
- Guarantee continuous supply of superheated water for workshop evaporators as well as building requirements, despite the shutdown of on-site Fluid Water (EF) production in 2024.
- Network pressure management via a second GMP container (pressure maintenance unit).
CLIENT REQUEST
- Extend evaporator operation beyond 2024.
- Install an intermediate loop to produce superheated water.
- Implement an autonomous system meeting high specifications.
- Conduct factory acceptance tests to ensure compliance before installation.
CHALLENGE
- Technical:
- Supply superheated water at 188°C and 23 bar at a flow rate of 210 m³/h, while integrating steam at 20 bar.
- Manage condensate recovery as well as cooling.
- Maintain stable pressure at 17 bar in the primary loop.
- Logistics: Conduct a full-scale test in a controlled environment.
- Reliability: Ensure redundancy for critical functions (pumps, valves, controls).
TIBBLOC SOLUTION
Modular and turnkey infrastructure:
- Pumps: Two pumps for water circulation, with automatic switchover in case of failure (normal/backup).
- Heating: Steam/superheated water heat exchanger to achieve required thermodynamic parameters.
- Condensate management: Complete collection, cooling (dedicated heat exchanger), and discharge system.
- Advanced control: Pressure maintenance and precise temperature control (188°C setpoint).
Automation and Safety:
- Control system to manage process parameters and signal any faults.
- Functional tests including failure simulations (power loss, sensor failure, etc.).
Flexibility and scalability: An outdoor-mounted substation, ready to use, adapted to site constraints.
PROFITS
- Workshop production continuity
- Redundancy of key equipment for continuous operation.
- Automatic safety shutdown in case of critical threshold exceedance.
- Pre-assembled and factory-tested substation, reducing installation time.
- Tests validating proper system operation before on-site integration.
OBJECTIVES
Ensuring business continuity during maintenance shutdowns.
CLIENT REQUEST
Unit shutdown
Our client was performing a chemical cleaning on their steam generator. This process, specifically cleaning the steam generator bundles, requires a steam supply, while air compressors are essential for bubbling operations. This therefore required an external supply of steam and compressed air to ensure the smooth running of the process.
CHALLENGE
Ensuring a continuous supply of steam and compressed air
The challenge is to provide a temporary solution capable of maintaining steam production (3 tons per hour) and compressed air (up to 1300 Nm³/h) during a shutdown period, specifically 24/7 for 11 days. These units must be reliable and compliant with safety standards.
