Abstract
An acoustic emission signal collector for monitoring leaks in furnace wall tubes employs a plurality of waveguides attached to the tubes and connected to a cross member. An acoustic emission sensor positioned on the cross member detects leaks which are propagated from the furnace wall tube to the cross member. An alternate embodiment includes tines or waveguides bent at an angle and attached to the furnace wall tubes.
Claims11
An acoustic emission signal collector, comprising:
- a plurality of waveguides attached to an object to be tested at a plurality of locations thereon;
- and
- a cross member connected to said plurality of waveguides.
An acoustic emission sensor for simultaneously monitoring a plurality of furnace wall tubes for leaks, comprising:
- a plurality of waveguides attached to the furnace wall tubes;
- a cross member connected to said plurality of waveguides;
- and
- means for sensing a signal positioned on said cross member, said sensing means identifying a leak in the furnace wall tube from the signal propagating along the tube, the waveguide and to the cross member.
