Zolo Hits Milestone in Steel Industry Technology

Posted on: Wednesday, December 30th, 2015

Zolo Technologies, the leader in Tunable Diode Laser Absorption Spectroscopy (TDLAS) for harsh
combustion environments, has now commissioned ZoloSCAN systems on more than 25 furnaces since
the introduction of the technology to the steel industry. The ZoloSCAN TDLAS system provides real-time
measurements of products of combustion and temperature which enables the optimization of EAFs,
BOFs and reheat furnaces.
Zolo has already installed and commissioned systems on over 80 heaters, boilers and furnaces in
industrial markets worldwide. In 2013, the ZoloSCAN was introduced to the steel industry. Readily
quantifiable fuel savings and quality improvements have led to the rapid acceptance by steelmakers of
the ZoloSCAN technology. Simple payback of capital typically occurs in less than 12 months.
“The steel industry has received the ZoloSCAN technology with great enthusiasm”, states Reed Sarver,
President of Zolo. “Our steel customers tell us that they are particularly happy with the response speed
of the ZoloSCAN, its low maintenance requirements, and its ability to make accurate, actionable in-situ
ZoloSCAN technology is provided exclusively by Zolo Technologies, Louisville, Colorado and utilizes
Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure oxygen, carbon monoxide, carbon
dioxide, water and temperature on a near real time basis, with a single laser path. ZoloSCAN provides
rapid process feedback (less than 2 seconds) for improved control of energy and metallurgical inputs to
the EAF process and end of oxygen blow measurement for BOF. For steel reheat furnaces, the
technology enables the implementation of as many as 24 laser paths from one ZoloSCAN system, which
in many cases supports the outfitting of two or three side by side reheat furnaces. In addition, the
capability to measure water vapor directly provides a method of leak detection, a long sought goal in
the steel industry. ZoloSCAN eliminates the troublesome and costly maintenance of traditional
extractive analyzers while providing a direct read, fast responding combustion diagnostic technology
and water detection system, unavailable anywhere else. Zolo Technologies is ISO 9001 certified and
designs, develops, manufactures, installs and services all of our products. www.zolotech.com ####
