I am involved in calculations of a HRSG boiler 32 m. height, 6 m. length and 3,6 m. width, horizontal tubes bundles, vertical gas flow (european type), inlet gas temperature 650ºC (1200 ºF). The tube bundles rest on two vertical perforated plates which are suspended by lugs with pins from the next upper bundle and finally all the weight goes to the top steel by rods. Casing is internal insulated and also suspended by rods from the top steel. Seismic coefficient is 0.3g. My question is:
All analogies that I have seen show no connection between bundles and casing then, how seismic horizontal forces are transferred from the hanging tube bundles to the seismic bumper ties of the casing? Anybody knows?
Thanks in advance.
