A Heat exchanger consists of jacketed pipe to increase dry gas for 5 Deg C by saturated Low Pressure Steam of 4.4 barg pressure. Shell side is using LP steam and temperature of Inlet & Outlet (design temperature) is 145/145 C, while pressure is 4.4 barg. Out let of shell side is a steam trap which discharge is joining the steam condensate header. The exchanger is a concurrent flow.
In practical scenario, outlet steam condensate temperature is too cooled (approximately 40 0 C) while 5 0 C temperature increase is maintained and inlet steam pressure is approximately 2 barg. Due to too cooled steam condensate joins the other sources of steam condensate which are approximately 100 0 C, there is hammering in the steam condensate header line. One suggest to keep the exchanger outlet steam condensate line heat tracing to increase the steam condensate temperature to avoid hammering. Will it works? Is there any other solution to avoid hammering?
Thanks in advance.
