Modular Structure Special Boiler Fly Ash Treatment Environmental Protection Compliance
Overview:
This special boiler outputs steam stably in a wide temperature range through natural circulation and multi-stage evaporator redundant design, adapting to the pressure-sensitive process requirements of the steam pipeline network of chemical plants. It adopts a distributed evaporation unit combined with an economizer preheating system to significantly reduce thermal inertia and improve response efficiency; the vertical open-air layout saves space, and the modular structure optimizes the adaptation to the renovation of old plant areas, taking into account both operational reliability and site adaptability.

Product Introduction:
This special boiler uses a natural circulation + multi-stage evaporator redundant design (four-channel dual evaporator + five-channel superheater) to stably output 1.2MPa, 220℃ saturated steam (fluctuation range ±10℃) in a wide temperature range of 1200℃ to 200℃, meeting the pressure-sensitive process requirements of the steam pipeline network of chemical plants. One to four-channel membrane water-cooled walls form a distributed evaporation unit, which is combined with a five-channel three-stage economizer to preheat the feed water to 137℃, ensuring that the evaporation system has low thermal inertia and fast response; the vertical structure + open-air layout solution reduces the plant area by 30%, which is suitable for the renovation of old plant areas.
Technical Specifications:
| Steam pressure | 1.2MPa |
| Steam temperature | 220℃ |
| Feedwater preheating temperature | 137℃ |
| Thermal inertia control | istributed evaporation unit + natural circulation design |
| Exhaust gas temperature | ≤200℃ |
| Steam temperature fluctuation | <1.5% |
| Floor space optimization | 30% less than traditional horizontal boilers |
| Operation and maintenance energy consumption reduction | 25% |
| Wastewater discharge rate | 3% |
Advantages:
(1)Highly stable steam parameters
Multi-stage evaporators are connected in parallel to buffer thermal shock, and the steam temperature fluctuation is less than 1.5%.
(2)Low maintenance operation
Natural circulation without forced pump group, operation and maintenance energy consumption is reduced by 25%, and the sewage discharge rate is only 3%.
(3)Compact layout
The vertical five-channel is vertically stacked, and the floor space is reduced by 40% compared with the horizontal boiler.
