Flue Gas Heat Exchanger | High Efficiency Flue Gas Waste Heat Recovery
High Efficiency Flue Gas Waste Heat Recovery
✅ Military-grade thermal design
✅ High heat recovery efficiency
✅ Customizable material & structure
✅ Dual value: energy saving + environmental protection
✅ Compact & reliable construction
Product Overview
Flue Gas Heat Exchanger is a high-performance waste heat recovery solution engineered by G2 Defense Technology. It extracts residual thermal energy from medium & high-temperature industrial flue gas and transfers heat to water, air or other working fluids for reuse.
Our FGHE recovers waste heat discharged from industrial kilns, boilers, coking ovens, blast furnaces and metallurgical furnaces. The recovered heat can produce hot water, hot air or steam for domestic heating, process drying, steam power generation and other industrial demands.
Flue gas waste heat accounts for the largest heat loss of boiler systems in power plants. When matched with dust removal systems, our flue gas heat exchanger improves dust collection performance and cuts pollutant discharge, helping enterprises achieve energy saving, carbon reduction and emission control simultaneously.
