ABSTRACT:
A carpet dye beck is provided with submerged combustion heating apparatus for heating dye solution in the dye beck, by discharging pressurized high-temperature gas directly into the dye solution. The discharge of pressurized high-temperature gas directly into the dye solution provides bubbling of the gas through the solution, with turbulent agitation of the dye solution, and promotes high-efficiency, cost effective heating of a dye bath.
