Sintering Waste Heat Boiler on Main Flue Gas Duct

Structural Composition
Evaporator: Core heat exchange element (finned tube/heat pipe), absorbs heat from flue gas.
Steam Drum: Separates and stores steam and water, controls water level and pressure.
Pipeline System: Connects the steam drum and evaporator, including steam and water pipes, valves, etc.
Accessories: Safety valves, water level gauges, thermometers, pressure gauges, etc.
Application Advantages
1、Energy Recovery: Converts waste heat into usable energy, reducing energy consumption in the sintering process (approximately 10% of total energy consumption in a steel plant).
2、Economic Benefits:The generated steam can be used to drive the main sintering exhaust fan (saving electricity).Excess steam can be used for power generation or other production processes.
3、Environmental Benefits: Reduces flue gas temperature, lessens the load on subsequent environmental protection equipment, and reduces carbon emissions.

The core application of sintering waste heat boilers in the main flue of sintering machines is the recovery of high-temperature flue gas waste heat. It is mainly used in the following areas:
Energy Recovery: Converting the 300-500°C waste heat from the flue gas in the main flue of the sintering machine into steam for power generation or process steam use, directly reducing energy consumption in the sintering process.
Iron and Steel Industry: This is a typical application in the sintering process of integrated iron and steel enterprises. It effectively supplements traditional waste heat recovery from annular coolers, improving the overall thermal efficiency of the entire sintering process.
Technical Approaches: There are two main options:
Built-in type: The equipment is installed inside the flue, requiring less investment and space, but maintenance is inconvenient.
External type: The system is independent and reliable, easy to maintain, but requires more investment and space.
