When innovation Acts for savings GAP 30-3-2 Recuperator/Economizer Technical datasheet The ACTE GAP-type heat recuperators are at the cutting edge of small-size waste heat boiler technology. Thanks to the combination of performance, reliability and compactness, the GAP-type heat recuperators make waste heat recovery within reach of all industrial processes. GAP heat recuperators: the combination of plates and pipes Plate exchangers are much smaller and lighter than pipe exchangers but are not always as effective. ACTE’s GAP exchangers are manufactured using a clever mix of pipes and plates, allowing a closed volume in which a liquid can flow, providing a much larger surface area for the same length: the doublet. Fluid Secondaryinle fluid - cold Exchange surface of a 1” pipe: 0.08 m2 per m Exchange surface of a doublet: 0.8 m2 per m Thanks to this, GAP recuperators allow energy optimisation on smaller size processes for which mainstream solutions are not suitable. 12” Chimney ducts get their dedicated waste heat recovery solution Secondary fluid -Fluid outle hot ACTE GAP Economisor Recuperator Steam turbin GAP 30-3-2: the optimisation of exchange surface and volume The GAP 30-3-2 waste heat recuperator has been designed to answer heat recovery needs for applications that require highly effective exchange within a small volume and that involve clean or slighty dusty fumes. The GAP 30-3-2 has been specially designed to fit within DN300 (12”) chimney ducts.

Water with 20% glycol Pressure Drop Zone Fumes flow rate [Nm3/h] Water side pressure drop [Pa] -Pressure drop curve Primary Side The flow rates given above have been calculated for a temperature difference of 20°C For any other temperature difference, the corresponding water flow rate is obtained using the formula below. The corresponding pressure drop is then determined following the initial - = Water flow rate [m3/h] Pressure Drop Zone Fumes flow rate [Nm3/h] Oil side pressure drop [Pa] -Pressure drop curve Fumes flow rate [Nm fh] Primary Side The flow rates given above have been calculated...

When innovation Acts for savings Exchangers in parallel: If the drop in pressure on the fumes is too great, it is always possible to put two exchangers in parallel, which will have the effect of dividing the fume flow rate by two. The thermal power recovered then represents twice the power given by the graph. The liquid flow rate to be taken into account is also twice that given by the graph. For example: for a flow rate of 2400 Nm3 per hour at 450°C, the graph indicates a pressure drop of 6000 Pa, which may be too high according to your specification. By putting two exchangers in parallel the...
