Advantages of Mixing Chamber Overhaul by Paya Mavad
Increasing Equipment Service Life through Specialized Overhaul
One of the key benefits of Paya Mavad’s mixing chamber overhaul is the significant extension of component life. Instead of completely replacing worn parts, engineering techniques such as reverse engineering, repair, reinforcement, and replacement of damaged sections are applied. This process enables the equipment to operate reliably for many years under harsh power plant conditions, minimizing the need for full replacement.
Improved Aerodynamic Performance and Reduced Pressure Drop
Overhauling the mixing chamber not only restores its mechanical structure but also enhances its aerodynamic performance. By precisely adjusting internal geometry, refining airflow surfaces, and controlling leakage points, pressure drop in the system decreases and overall power plant efficiency improves. This is especially critical in plants with high energy consumption.
Economic Savings Compared to Full Replacement
The cost of completely replacing the mixing chamber can be very high and sometimes economically unjustifiable, especially when importing specialized parts is necessary. In contrast, a proper engineered overhaul can save up to 60% of these costs. This method is very cost-effective and reliable for industrial and power generation units.
Thorough Inspection and Quality Control at All Stages
Throughout the overhaul process, from start to final delivery, Paya Mavad conducts multiple specialized inspections, including Non-Destructive Testing (NDT), dimensional checks, and metallurgical analysis. These ensure the final part meets international power industry standards, with full documentation and evaluation at every step.
Use of Materials Resistant to Corrosion and High Temperatures
One of the main challenges in power plant equipment is resistance to corrosive environments and high temperatures. Paya Mavad employs materials suitable for high-pressure and high-temperature operational environments during the mixing chamber overhaul. This smart material choice significantly increases resistance to thermal and chemical erosion.
Reliance on Local Technical Expertise with International-Level Quality
The mixing chamber overhaul by Paya Mavad’s engineering team is based on indigenous technical knowledge, yet the execution quality competes with reputable international brands. This not only reduces dependency on foreign suppliers but also enhances the competitive capability of domestic industries regionally and globally.
