This is a view taken from just inside the firebox door, looking towards the front of the engine. The fire brick is visible as is the atomizer, which uses steam to propel a spray of oil. The burning oil bounces off of bricks lining the back sheet of the firebox. The hot gases created by the fire then travel through the flues which are seen below. The hanging black strips are built up oil residue.
After passing through the flues, the gases are exhausted through the smokestack. This is a view looking up the petticoat pipe and inside the smoke stack. The blower line and the larger air compressor exhaust are also visible. The same components are visible in the picture below.
