Waste Heat Recovery Unit for High-Temperature Flue Gas from Oxygen-Blown Gasifier

Features: 
High-Temperature Resistant Design: The heat exchange elements are made of high-temperature resistant alloy materials (such as 310S stainless steel, Inconel alloy, etc.) or ceramic materials, capable of withstanding the scouring of high-temperature flue gas at 800-1200℃ for extended periods, avoiding deformation, corrosion, or oxidation at high temperatures.
Dust-resistant/Anti-coking Adaptability: Addressing the high dust content and potential coking components in pure oxygen gasification flue gas, the heat exchange channels are designed with large apertures and low resistance, or equipped with online cleaning devices (such as pulse soot blowing and mechanical rapping) to reduce the impact of dust accumulation and coking on heat exchange efficiency.
High-Efficiency Heat Exchange Structure: Optimized heat exchange surface layout (such as staggered tube bundles and finned heat exchange) increases the heat transfer area and improves the heat transfer coefficient, reducing heat loss and ensuring sufficient absorption of heat from the flue gas.
Strong System Adaptability: The structural dimensions and interface design match the flue gas emission volume and pressure parameters of the pure oxygen gasification furnace, allowing seamless integration with the gasification system without affecting the normal operation of the main equipment; some models support modular design for easy installation, maintenance, and expansion.
High Operational Stability: Equipped with temperature and pressure monitoring devices, it can monitor the heat exchange status of flue gas and the medium in real time, avoiding equipment failures caused by over-temperature or over-pressure; the airtight sealing structure prevents flue gas leakage or air infiltration from affecting gasification efficiency.

Core Application Areas:
Coal Chemical Industry: Used to produce methanol, synthetic ammonia, olefins, hydrogen, etc. The recovered steam primarily drives large compressors and meets process requirements, making it a core component for reducing energy consumption.
Combined Generation Systems: Flexible, providing both electricity and steam for power generation and chemical product production simultaneously, achieving cascaded energy utilization.
Emerging Areas:
Biomass/Waste Gasification: Used to produce green fuels or generate electricity.
Hydrogen Production Coupled with Carbon Capture and Storage (CCUS): Provides energy for energy-intensive carbon capture processes, reducing their costs.
