Unfired Steam Boilers and 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).

  1. Process Steam: 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.
  2. Clean Steam: 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.
  3. Pure Steam: 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.


Ace Series Hot Water Boilers


  1. Design: Ace started with the inclined watertube boiler design concept.  This design has an extremely low pressure drop, minimal impact on system pump sizing, and normally does not require primary/secondary piping configuration.  The incline of the tubes prevents air accumulation and the associated waterside corrosion.  To prevent thermal shock, Ace has incorporated expansion joints at each corner to allow the tube bundle to float freely as it expands and contracts
  2. Emissions:
    1. Maintenance with Ace Heating Solutions, LLC. has always been at the forefront of meeting regulatory standards for emissions.  Being located in Southern California has enabled Ace to see where the emissions standards are headed and their R&D department has kept ahead of those standards.  Currently, Ace has burner designs to meet 9, 12, 20, or 30 ppm NOx requirements and 50 ppm CO requirements.
    2. From a maintenance perspective, there is a lot to like about the Ajax inclined watertube boilers. This design allows for visual inspection of the tubes, which can also be mechanically cleaned in place.  Tube replacement is with low cost, non-proprietary tubeswhich are rolled into place without the need of an ASME code welder.
  3. Conclusion
    1. Ace manufactures the inclined watertube boilers in sizes from 150,000 to 21,000,000 Btu/hr and for maximum pressures and temperatures of 125 psig/250°F or 150 psig/370°F.  The Ace inclined watertube boiler has earned its bullet proof reputation and is designed to last for many decades.
    2. Ace Heating Solutions, LLC. designs and manufactures a comprehensive line of boiler and commercial water heating products. With over eight decades of experience, the company offers high quality, heavy duty products with reputations for reliability, serviceability, and cost effective operation.


Ace Steam Boilers H & S Series


The ACE Series Steam Boilers .boast the same advantages as other Ace boilers: dependability, quiet operation and long life. Inclined tubes provide uniform heat transfer, resulting in high fuel economy and long boiler life. 2″ O.D. tubes (steel or copper) are rolled into large headers on both ends producing excellent boiler circulation. 2″ O.D. tubes are less restrictive than smaller O.D. tubes. Our non-proprietary tubes are less costly for tube replacement. Ace’s straight tube design allows for easy inspection of tube condition

  1. Water Tube Bundle Assembly: Constructed and Stamped to ASME Code, the water tube assembly is individually rolled into the headers and supported by a rugged steel frame with expansion joints at each corner. This allows the entire tube bundle to float freely as it expands and contracts preventing thermal shock damage. The elimination of air bubbles and the prevention of waterside corrosion is accomplished by sloping the tubes upward 1/2″ per linear foot from the rear to the front.
  2. Atmospheric Burner Assembly:Multiple burner heads make up the burner assembly, each with its own venturi and orifice. The cast-iron burner head has long been recognized as the simplest, most trouble-free gas burner available.
  3. Pre-Mix/ Low NOx Burner Assembly:  Ace boilers use proprietary 9 and 12 ppm NOx burner assemblies that combine simple design and long-term reliable service. The low NOx is achieved by using a perforated burner plate, gas injector, and a low energy gas-air mixing sections in a clean manifold design.
  4. Highlights: SR & HR Series:
    1. Burner Design: Standardized across product lines
    2. Heat Exchanger: Increased surface area means greater efficiency
    3. Efficiency: 83% (atmospheric) / 84% – 85% (forced draft)
    4. Size: Lower height due to reduced size of combustion chamber
