Kettles
Jacketed steam kettles are pressure vessels that use steam pressure to heat liquids or other materials. They are large containers that can be used to melt the asphalt on a job site and transport tar for roofing applications. Jacketed steam kettles most often contain fluids at pressure levels greater than that of atmospheric pressure. Kettles contain a wide variety of substances used for various industrial applications including the chemical, pharmaceutical, food and beverage, oil and fuel, and plastic industries. The substance contained and the industrial applications of the kettle determine such design components as vessel material, size, shape, temperature, and pressure level.
There are two different types of jacketed steam kettles: direct-fired jacketed steam kettles and indirect-fired jacketed steam kettles. Direct-fired jacketed steam kettles use an independent source of energy to produce steam within the kettle. Indirect-fired jacketed steam kettles, on the other hand, use an outside source of energy to produce steam within the kettle.
