Q1: What are the primary factors Zexuan considers when custom-designing a waste heat recovery system for a plant?

A: Our engineering team performs precise thermodynamic calculations based on four critical data vectors: the exhaust gas flow rate, the inlet/target outlet temperature profile, the chemical composition of the flue gas (to prevent acid dew-point corrosion), and your facility's specific utility demands (e.g., whether you need to generate steam, hot water, or pre-heat process air).

Q2: How does your equipment prevent corrosion and ash clogging when handling dirty, heavy-particulate flue gas?

A: To eliminate clogging, Zexuan utilizes optimized tube-pitch geometries and integrates automated mechanical or sonic soot-blowing manifolds. To fight corrosion, we upgrade critical contact zones to heavy-gauge SS316L or high-nickel alloys and implement smart PLC-controlled bypass valves that maintain flue gas temperatures safely above the acid dew point during low-load operation.

Q3: Can this waste heat recovery system be retrofitted into our existing third-party boilers or RTO units?

A: Yes, absolutely. Zexuan specializes in customized industrial retrofits. We utilize advanced 3D laser structural modeling and computational fluid dynamics (CFD) to design seamless duct tie-ins and customized flange configurations that perfectly match your existing layout, ensuring optimized pressure drops and minimal plant turnaround downtime.

Q4: What is the typical Return on Investment (ROI) period for a Zexuan waste heat recovery installation?

A: While the exact timeline depends on your local fuel costs and operational hours, most industrial facilities achieve full capital payback within 12 to 24 months. By dramatically reducing your daily auxiliary fuel consumption (natural gas, oil, or coal), the system provides immediate, measurable cost savings from day one of commissioning.
