Unfired Steam Boilers
Ajax unfired steam generators are engineered to meet specific steam needs for commercial and industrial applications with local steam requirements and an available supply of supply of steam, high temperature water, or thermal fluids from a central boiler plant. These boilers are also applied in applications where decoupling steam from a central boiler plant is required to prevent cross contamination from the boiler chemicals or process chemicals in the return condensate, such as in pulp and paper processing.
Installed in Universities, Hospitals, Hotels and Industrial Buildings, these units are offered as vertical or horizontal tank configurations (shown above). For smaller steam outputs, a Mini-Pack style steam generator is also available.
Unfired steam boiler tube bundles and/or drum can be fabricated using materials that will be cost effective for the process steam condition. These can range from copper tube bundles and pressure vessel quality steel to tube bundles made from cupro-nickel or stainless steel tubing and drums fabricated with stainless steel.
Clean steam unfired steam boilers provide clean steam by using feed water that is free from boiler water treatment chemicals. Clean steam is used by the food industry for cooking and cleaning and is also used for many sterilization and humidification applications.
More and more applications are requiring ultra pure steam for sterilization in Bio-science research, pharmaceutical research and/or processing, medical sterilization and high-tech clean room humidity control. Pure steam boilers are normally fabricated with special high quality stainless steel pressure vessel material and components to handle the aggressive feedwater used in these applications.
