Working for an engineering company, I participate in the enquiry of a refinery boiler (burning heavy fuel oil) to produce 55 ton/h of steam (41 Barg, 400 deg C).
1. Our Client wants to look into sonic soot blowers (acoustic cleaners) and either install them (instead of steam soot blowers)or at least have provision for them. Is this realistic? Two probable boiler suppliers do not recommend sonic soot blowers.
2. One of above suppliers proposes serrated fin tubes for the risers (tubes receiving heat and evaporating part of their water content into the steam drum). The boiler is pressurized, with membrane wall. Finned tubes for risers may be odd, contrary to those for economizer or even superheater. But I do not have experience on modern boilers. Are finned tubes realistic for risers?
