Systems Containing Contact Economizers for Flue Gas Heat Utilization

摘要: A reference is made to the fact that a significant part of heat generated by combustion, lost in atmosphere with exhausted flue gases. Contact economizer systems are considered which help utilize this heating up water before entering boiler or urban supply central network, as recycled back plant. Attention drawn some features new contact economizers allow pressure drop values low 10–20 mm head at high gas superficial velocities, i.e. 3 m/s. New process flow charts helping higher temperature levelsby simultaneous reduction nitric oxides emissions down %, given. The method developed for designing such described, and data obtained experiments industrial authors, presented.
