: Have you checked all your combustion seals. also does the vibration get worse or better above 1/3 fire. Do you have a choke ring in the morrison tube? Do you have any method of stack pressure control? Just a few of the problems I have run across.
: Good luck
Steve,
Thank you for the swift reply.
Combustion seals are ok, The vibration occurs only at about 30% of the load. Above and below this load the phenomenon disappears. The pressure in the combustion chamber is than slightly less than 0. There are no stack dampers manually ore automatically controlled.(We are thinking about it but it has last priority because of its cost.)
What do you mean by "a choke ring in the Morrison tube"?
