Abstract: A jet impingement heat exchanger is provided for use primarily in heating a dye solution in a dye beck for dyeing carpet, the heat exchanger being made up of a source of high temperature combustion products, an inner chamber wall having a surrounding outer chamber, the inner chamber wall having a plurality of perforations for directing jets of the hot combustion products to impoinge against the wall of the outer chamber, effecting heat transfer to the dye solution through this wall. Additionally, the invention provides for the use of a heat exchanger in combination with a submerged combustion apparatus, and methods for heating the dye solution using this combination.

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.

Abstract: A gas heated direct fired center tube revolving ironer for use in an automated fabric ironing environment features improved roller surface temperature distribution control. An adjustable hot air recirculation system with a venturi throat, a high momentum gas burner, an improved temperature control system and an exhaust blower cooperate to provide an even temperature along the ironing surface. Multiple high and low temperature controls provide backup and ensure accuracy and safety. The gas fuel consumption is minimized thereby reducing operating costs.
