Unfired Steam Generators
Ace boilers perform dependably and quietly, engineered to meet specific steam needs for industrial, institutional and commercial facilities with special steam requirements and point-of-use steam needs. A proven solution over the last 35 years, the quality u-tube bundles provide uniform heat transfer, resulting in high thermal efficiency and long boiler life. Double-wall bundles are available.
Typical heating media for applications include steam, high temperature water, and thermal fluids.
Installed in Universities, Hospitals, Hotels and Industrial Buildings, these units are offered as slim-style units (shown at right), and horizontal tank units (shown below).
Unfired steam boilers are used to protect fired boilers from harmful chemicals in the return condensate, such as in pulp and paper processing. 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.
