Modular Design Redefines Mine Ventilation Efficiency and Availability

TLT-Turbo have released a modular mining ventilation fan concept that simplifies the planning of ventilation systems for customers while still providing the benefits that are synonymous with TLT-Turbo products including increased efficiency and lower power consumption. The Modular Mining Fan concept offers a range of modular solutions that cater to almost every ventilation requirement and aims to set a new standard for mine ventilation innovation.

The range offers a modular design that results in a well-engineered and efficient ventilation system at lower operational and maintenance costs. Customers have the flexibility to order required units and build on the system as their requirements grow – resulting in lower initial expenditure with more economical options for system expansion.

German engineering and extensive R&D have resulted in the highest product quality. This, paired with TLT-Turbo’s field-proven technology, provides a high-end pre-existing solution which means that mines will not incur the design and engineering costs that are usually associated with bespoke ventilation installations.

The modular concept makes it extremely convenient for customers in the mining industry to plan, design and optimize their ventilation systems to optimally benefit their operations. The modular approach eliminates guess work and ensures that the entire system can be planned to deliver predictable and accurate performance.

The modular design offers seven base fan sizes combined with six different hub sizes to ensure the right fit for all requirements. Numerous customizable and adaptable parts offer flexibility for specific customer needs. Add-ons have been developed for all seven base sizes allowing for modular pre-existing upgrades to meet individual requirements.

The modular components are designed to slot together, and no additional engineering is needed to ensure that different modules fit together to suit a specific operating environment. The advanced design ensures total fan efficiency of up to 90%, lowering the operating costs while maintaining full performanceThis entire offering is available at lower initial costs with short lead times for supply.

All the modular components can be manufactured simultaneously and are commissioned and installed once completed. Expansion of an existing TLT-Turbo Modular Mining Fan system is a simple process as new components are slotted into the existing system with minimal effort. Typically, ventilation systems need to grow or be upgraded as production demands increase. Where a major overhaul would usually be required, TLT-Turbo’s modular installation can be expanded by installing additional components to the existing system to scale up ventilation capacity or replace existing modules with higher specifications to optimise or upgrade the system.

With the modules being manufactured at state-of-the-art TLT-Turbo manufacturing facilities, customers can be assured of the highest quality end product.

Corrosion in Power Plants

 

Energy technology is undergoing global transformation. Rapidly expanding renewable energy and other, more volatile power generation plants require significantly higher flexibility of conventional plants. This has resulted in a number of new challenges for ventilation equipment, including:

  • An increased number of start and stop operations
  • Fewer full-load hours
  • Increased partial load operation
  • Lower exhaust gas temperatures due to residual heat utilization
  • Smaller gap to acid dew point  

These factors cause an increased load on the systems which carries increased risk of corrosion during operation. This favors dew point corrosion, which can lead to total failure of fans and system components.

TLT-Turbo offers you a tailor-made solution for your plant by implementing effective corrosion protection measures to maintain uptime of your fans.

Efficient Protection against Corrosion

TLT-Turbo Corrosion Protection for fans includes two key actions: Preventing corrosion where possible and protecting components where corrosion cannot be prevented.

Avoiding corrosive conditions:
  • Preventing or reducing leakage of sealing air
  • Heating of fan components
  • Optimization of insulation
Use of corrosion resistant materials:
  • Weather resistant steel
  • Polymers and polymeric coatings
  • Stainless steel
  • Ni-based coatings or base materials

In order to select the measures suitable to preventing and addressing corrosion on fans operating at your facility, TLT-Turbo conducts an individual corrosion risk assessment. This assessment is based on your operational and environmental conditions.

TLT-Turbo provides further support by conducting an analysis of your specific operating conditions, e.g. on a dew point measurement based on a plant inspection.

Contact TLT-Turbo to discuss your corrosion protection needs and to find the right service package to suit your on-going requirements.

Optimal Protection against Corrosion for Existing Plants

TLT-Turbo conducts corrosion risk assessments and implements suitable preventative measures when designing and manufacturing new fans. These measures can also be carried out when retrofitting existing plants or as part of preventative maintenance during a scheduled shutdown.

Contact your service representative or the TLT-Turbo Service Department for more information on conducting a tailored risk assessment at your facility.

TLT-Turbo Optimizes Air Flow at European Power Plant Based on CFD

In TLT-Turbo’s 145-year long history of developing centrifugal and axial fans, every fan has always been carefully evaluated through extensive testing before being deemed fit for application. These tests were greatly enhanced when computational testing became available. More recently, Computational Fluid Dynamics (CFD) simulation has greatly enhanced not only TLT-Turbo’s ability to conduct thorough product testing but has also created opportunities for developing new and improved fan types.

According to Sabine Groh, Product Manager for industry fans at TLT-Turbo in Bad Hersfeld, Germany, every TLT-Turbo fan type once was carefully evaluated and aerodynamically measured in aerodynamic test stands before being released for application in the customer’s operating environment. “The arrival of stronger computer performance has allowed us to utilize CFD simulation which has had a massive effect on our ability to develop new products and to improve existing fan types.”

Groh explains that CFD has numerous advantages, all of which have become integral to TLT-Turbo’s product development. One of the greatest advantages is that CFD has enhanced the understanding of flow phenomena more efficiently than empirical testing. By using CFD it is possible to zoom in and out of any area within the simulated geometry to determine most advantageous or disadvantageous parts or geometries. With examination options such as vectorplot, a detailed analysis of the direction within the flow is possible. Similarly, using streamlineplot or velocityplot provides a detailed view of irregularities or aerodynamic phenomena.

“This analysis helps us understand the parts or geometries that cause flow separations and turbulence which allows us to address these in our product design. We can use the CFD simulations for the development or improvement of different fan types, blade geometries or spiral casing for centrifugal fans,” says Groh.

Additionally, TLT-Turbo uses CFD to understand problems in the flow of a given customer application that might result in a loss of pressure, efficiency or untypical wear of parts exposed to the flow. This equips TLT-Turbo with the knowledge needed to carry out retrofitting and product enhancements to ensure improved future performance (see flow optimization use case below).

Flow Optimization Case Study

At a European power plant, a centrifugal fan was controlled by an inlet vane control. During operation, the blades of the vane were rattling after a while and needed repair. After replacement, the same blades were showing the same failure after some operation time. Figure 1 below shows the blade of the inlet vane control dismounted of the socket.

Figure 1: blade shaft of inlet vane control with too much clearance in the socket

It was assumed that the flow was not homogeneous before it reached the inlet vane control blade, and the use of air guiding plates was considered to correct the flow. Through the use of CFD, this pattern could be more deeply investigated resulting in a superior solution.   

Groh unpacks the process and explains how a better solution was found using CFD: “Each CFD requires four process steps. The first step is the creation of the 3D model of the geometry to be analyzed. The second step is discretization. This involves creating a three dimensional computational mesh in the model for the volume in which the medium flows. The third step is defining the boundary conditions for the simulation and as the fourth step, the simulation of the flow can be performed.”

In this specific instance, the ductwork ahead of the malfunctioning inlet vane control, the blades of the closure unit itself and the suction box behind the closure unit were all rendered in 3D models. Figure 2 below shows the geometry that was analyzed in detail in the computer model. The ductwork upstream and downstream was included to ensure the stability of the calculation in the simulation.

Figure 2: Scope of detailed simulation in the plant

After meshing of the 3D model, a simulation was performed to determine the direction of the stream in the ducting ahead the inlet vane control in more detail. Figure 3 below shows the result of the simulation.

Figure 3: direction of the stream in the ductwork ahead of the inlet vane control

The simulation showed that a separation of the stream led to turbulence in the flow ahead of the closure unit. With the validated conclusions of the simulation, TLT-Turbo was able to investigate different proposed solutions to remedy the problem. Figure 4 below shows the streamline plots of these different solutions.

Figure 4: Comparison of different countermeasures against the turbulence

The conclusion was that a combination of two countermeasures in the ducting would be the most advantageous solution. So ahead of the closure unit, TLT-Turbo installed a suction nozzle that helped guide the incoming flow into the duct (see blue colored suction nozzle in Figure 5 below).

Behind the closure unit, TLT-Turbo also welded a split plate (blue colored plate in Figure 5) into the suction box to help guide the stream further into the inlet vane control ahead of the centrifugal fan.

Figure 5: implemented solution to solve the problem with the inlet vane control

In Conclusion

The use of CFD has become an essential tool to TLT-Turbo for the development of new and more efficient fan types and blades. Instead of building numerous test models for each proposed blade or impeller type with subsequent aerodynamic model testing, different geometries can be compared in the CFD simulation directly. However, the value of CFD doesn´t end there. Increasingly, TLT-Turbo is also using CFD for aerodynamic optimization of flow in customer operating environments.  That includes solving aerodynamic problems such as the example above, and for reducing wear, pressure loss or in general creating a more homogenous flow of the gas or air in the plant to maximize efficiency. Finally, the success of performance improvements as a result of replacing a fan in an existing casing, can be verified.
