1/3/2008 · The industrial boiler is a front wall-fired unit with 70,000 kg/h steam capacity. It was equipped with four burners in a two by two array on the front wall at two elevations, 10.4 m and 12.2 m, respectively. The reburning coal was injected through 6 ports at elevation 13.4 m, with two ports on the front wall and four ports on the rear wall.

Pulverised Fuel - an overview | ScienceDirect Topics

Burners are typically located on the front wall or both the front and rear walls, which is typically referred to as opposed firing [79]. Figure 4.26 depicts a side view of a front wall-fired boiler. FIGURE 4.26 .

Firebox (steam engine) - Wikipedia

Firetubes are attached to one wall of the firebox (the front wall for a longitudinal boiler, the top for a vertical boiler) and carry the hot gaseous products of combustion through the boiler water, heating it, before they escape to the atmosphere.
