Five Stage Economizer Membrane Wall Boiler Heat Recovery Chemical Production

The membrane wall boiler features a vertical membrane wall radiation section that enables efficient heat transfer through fully sealed radiation heat exchange. Designed for flue gas environments exceeding 1300°C, it incorporates a single steam drum high-position suspension design fixed to the tail steel frame, significantly simplifying the support structure and enhancing overall system stability. The thermal system utilizes a five-stage countercurrent economizer to synergistically enhance flue gas waste heat recovery, achieving ultra-low temperature exhaust conditions. Spiral fin tube bundles and staggered superheaters further improve steam temperature and heat transfer efficiency, fully meeting medium-pressure steam parameter requirements.

This advanced thermal system combines vertical membrane wall radiation section technology with a five-stage counterflow economizer architecture. The single steam drum high-position suspension design (fixed on the tail steel frame) achieves ultra-low temperature exhaust conditions of 194°C through membrane wall fully sealed radiation heat exchange (surface temperature tolerance 1300°C) and five-stage economizer counterflow coordination. The superheater utilizes spiral fin tube bundles with staggered layout, raising steam temperature to 450°C under medium pressure of 4.2MPa. Ideal for glass kilns, metallurgical blast furnaces, and other flue gas waste heat recovery applications above 1300°C.
