9. Why is actual firing rate kept above steady state?

10. In this graph, which two temperatures are an indication of firing rate?

Alt = Labeled Fig. 18 Entrance cone. Depiction of a barrel laying on its side and it's flared on the left side, with arrows going from the right pointing left, marked Primary air flow. On the top of the barrel is a capped pipe protruding, marked Low pressure tap (duct pressure). The left edge of the flared portion is marked Perforated screen, and the flared portion plus a portion of the barrel's left end is depicted as being inside thte wall of the windbox and is marked as such. Just above the barrel and protruding from the wall of the windbox is a capped pipe marked High pressure tap (windbox pressure).

Returning to the second pass rear wall inlet header, flow is the same for both units. Flow travels up the second rear wall pass and feeds the screen inlet header. Flow is up behind the arch and through the screen tubes immediately ahead of the SSH {Secondary SuperHeater} inlet tube bank (Figure 22). The screen tubes are widely spaced tubes which support and complete the furnace rear wall circuit.

Alt = labeled Fig. 20 Furnace wall mix construction. Depicts the pipe layout of connections between the 1st pass header (lower left side) and the 2nd pass inlet header (lower than the other header but in the center of the image). To the left between the two headers is the label "To mix and 2nd pass inlet header " betwixt two arrows; top arrow shows pointing away from the 1st pass outlet header to the label, and the other arrow points away from the label toward the 2nd pass inlet header.
