Boiler plants and steam systems are responsible for a major portion of the energy used in a facility. Bluestone is experienced in evaluating the operation of boilers, steam systems and condensate return systems and identifying cost effective improvements that reduce energy use.

Our engineers have designed and installed many efficiency upgrades in boiler plants and steam systems including:

Efficient condensing boilers
Variable Frequency Drives (VFDs) on forced draft fans and boiler feed pumps
Boiler Economizers
Steam trap/steam control valve upgrades
Conversion of burner controls from simple "jack shaft" to PLC based controls with exhaust gas trim

Peabody Terrace: Harvard

Bluestone designed and implemented a steam balancing valve retrofit for Harvard University that included replacing over 390 steam valves in three high-rise towers. The combined steam and maintenance savings from replacing the valves, traps and hoses resulted in an annual savings of over $51,000.

Annual Savings: > $51,000

Simple Payback: < 5 Years
