The explosion took place at a seam in the front part of the bottom of the boiler just over the fire. This rupture allowed the sides to to expand, until the boiler was completely destroyed and torn into seven pieces.
The cause of the explosion was supposed to be the defective state of the seams over the fire, which, being placed longitudinally, were in the weakest position.

Two Tube Cornish, 15ft. long, 6ft. diameter, tubes 1ft. 8in. diameter, 3/8 inch plates, 40 lbs. The heat was supplied by two furnaces, one of which played into each tube.
The left hand tube collapsed from shortness of water, and tore away from the angle iron in the front plate, and allowed the contents to issue violently and scatter the brickwork, but the boiler was not disturbed.
