Hot Swappable Expansion Interface Waste Heat Boiler 78000Nm3/H ‌Flue Gas Parameters

Hot-Swappable Expansion Interface Waste Heat Boiler for Production Line Transformation

This waste heat boiler features a 3D foldable modular architecture that enables embedded installation in non-standard spaces, making it ideal for waste gas recovery from discrete heat sources such as food factory ovens and paper mill cooking tanks. Utilizing welding-free fast alignment technology, it reduces floor space by 38% compared to traditional solutions. The hot-swappable expansion interface (ISO14461 compliant) supports 1:1 synchronous capacity expansion of waste gas recovery units and production equipment during production line transformation. An intelligent waste gas flow control algorithm ensures system pressure loss fluctuation remains ≤3% when multiple modules are connected in parallel.

Built on the П-type two-stage thermal protection architecture (front water cooling protection section isolates 1280℃ flue gas impact + rear water cooling section stabilizes heat flow distribution), this innovative system employs multi-stage steam confluence technology (self-produced saturated steam 38.95t/h + external steam 26.35t/h) and a dual-medium heat network supply system (external hot water 26.89t/h). This configuration achieves closed-loop heat-electricity-water trigeneration for methanol to olefins (DMTO) units. Through high-temperature superheater-low-temperature superheater gradient heat exchange design (water spray desuperheater provides precise temperature control ±5℃) and five-level heating surface modular layout (evaporation section + high/low temperature economizer), the system converts 78000Nm³/h ultra-high temperature flue gas waste heat into 65.3t/h industrial steam (4.5MPa, 420℃). Exhaust gas temperature is reduced to 170℃, with heat recovery efficiency 18% higher than traditional boilers, meeting carbon capture and energy cascade utilization needs for chemical parks.
