Boiler Cleaning and Ash Handling Business to Better Serve our Customers
The company and brand you recognize as "Diamond Power" entered the boiler cleaning business in 1903 and has operated as a Babcock & Wilcox company since 1922. Today, B&W Diamond Power® boiler cleaning systems, while much more elaborate and sophisticated than they were a century ago, still serve the same purpose: to keep boilers operating at peak efficiency.
The reliability and efficiency of your operations is important to B&W.
Trust that B&W will continue to offer the innovative and proven Diamond Power® technologies and support for products including boiler cleaning technologies such as IK™ retractable, HydroJet ® and other boiler cleaning systems / sootblowers.
B&W's Allen-Sherman-Hoff® provides ash and material handling solutions. As part of our complete environmental technologies line, we continue to provide a variety of ash and material handling solutions, from completely dry bottom ash handling to fly ash and petroleum coke processing. These technologies offer environmentally sound solutions to address wet FGD (scrubber) wastewater and mitigate ash storage ponds.
Allen-Sherman-Hoff’s business initially consisted of the supply of cast iron hoppers for coal storage and the collection and conveyance of bottom ash below the boilers.
A-S-H introduces its complete line of HYDRO-EJECTOR jet pumps in 1952.
The Allen Family retained control of the company until 1963 when the assets of the ash handling group were purchased by the Baldwin-Lima-Hamilton Company and a new corporation named Allen-Sherman-Hoff, Inc. was formed. This new company operated first as a subsidiary, then as a division, of Ecolaire Incorporated.
Ecolaire establishes the offices of A-S-H in Malvern, Pennsylvania.
A-S-H successfully negotiates the technology transfer contract with the People’s Republic of China, establishing A-S-H’s dominance of the ash handling industry in the PRC. A-S-H was also awarded the two largest ash handling system contracts ever tendered at that time, both for Taiwan Power Company’s Taichung Station.
Allen-Sherman-Hoff advances its technology development in dilute-phase transport systems, pressure dense-phase transport systems and mechanical drag conveyors.
