Furnaces are used in manufacturing and the oil and gas sectors. Furnaces accumulate soot over time, which clogs the system and reduces efficiency.

Soot removal can be undertaken using air-flow, flushed through a furnace. The types of soot-blowers available include mounted rotary units or lances which can be connected at several points along furnace tubes. Retractable lances can treat target areas of the furnace.
