Objective: Improve makeup water quality for operation
within the boiler facility.
Solution: Implement water treatment facility upgrades for
improved control of filters, softeners, dealkalizers, boiler chemical feed,
and auxiliary water treatment equipment. Steam Plant Systems has
completed projects for several customers involving design engineering,
project drawing, PLC logic development, HMI interface configuration,
equipment manuals, and startup.
Objective: Custom engineered burner management
system for critical operations.
Solution: Design and build a redundant system for avoidance of
boiler outages due to flame safety system component failures. All
critical components were designed with full redundancy for reliable
operations. In addition, major components are field replaceable
without requiring boiler shutdowns.
Experience: Fireye, Siemens QUADLOG
Objective: Provide integrated boiler control &
flame safety for critical operations.
Solution: Using available control technology and in-depth knowledge of
NFPA codes, design a system which meets the unique requirements of both
boiler control and flame safety without sacrificing ease of use or common
software platforms. Steam Plant Systems has accomplished this goal on
several projects for customers in the power generation, pulp & paper,
semiconductor, institutional steam distribution, and chemical industries.
Experience: Siemens APACS+ and QUADLOG
Objective: Fast track installation of leased
boilers for new powerhouse.
Solution: Steam Plant Systems mobilized an engineering team for
design and drawings required to install the boilers and key auxiliary
equipment. Completed package included drawings for boiler
installation, 400 psig steam systems, feedwater systems, condensate return,
makeup water, HP drains, 480 VAC electrical, and instruments/controls.
Objective: Modernize outdated boiler control
Solution: In a typical year, Steam Plant Systems will complete several
of these projects, ranging in size from single loop controls on small
commercial boilers to large distributed control systems spanning an entire

Objective: Modernize outdated chiller control
systems for five (5) 5000 ton chillers.
Solution: Install an Ethernet based system with PLC-5 chiller
controls (Ethernet based), SLC-500 safety controls (DH+), and industrial
computers running RSView software. The system has been on-line and
operating successfully for over six years.
Experience: Allen Bradley PLC-5, SLC-500, RSView Software.
Objective: Retrofit outdated controls in two (2)
remote hydro-electric stations.
Solution: Install new PLC control system in each of the two (2)
stations with fiber-optic communications between the two sites.
Provide HMI interface using redundant I/O servers, client workstations, and
remote operation via T1 line and additional client stations located 100
miles from the main site.
