Since our very founding as a mechanical engineering company, our technical expertise in power plant upgrades has constantly progressed.  Our services to support power plant upgrades now encompasses our entire spectrum of disciplines including mechanical, electrical, structural, civil and architectural services.  We support universities, industries and municipal clients with services for coal-fired systems, gas-fired CHPs, and hydroelectric facilities.

Project Examples Follow:


7MW Gas-Fired Industrial Combined Heat and Power: Power Uprate Project
Numerous design projects have been completed to increase the power boiler capacity and resolve steam line cracking issues:

• Economizer system analysis and modifications to increase energy recovery by 30%.
• New feedwater pump for desuperheater and PRV station.
• New small feedwater pump for low steam use periods with a turbine system for power generation and 15psi steam supply to the deaerator system.
• Pipe stress analysis using ALGOR cyclic fatigue analysis.

60,000PPH Central Plant Boiler: Mud Drum Heater System
A mud drum heater system was designed for a university central plant steam boiler to allow improved cold start and decrease corrosion.



Central Plant Coal-Fired Combined Heat and Power: Multiple Projects
Numerous designed steam plants and chiller plants have been designed for Virginia Tech since 1918. Our legacy projects include three 60,000PPH gas/oil-fired steam boilers and a 100,00PPH coal fired power boiler. In recent years, we have completed designed for several modifications under a term contract with the University.

• New fly/bottom ash storage silo, conveyors and truck loading station.
• New fly ash/lime waste silo to separate for beneficial use.
• New lime storage, slurry systems and spray dryer absorber for flue gas desulfurization.
• Replaced forced draft and induced draft fans for boiler uprates.

10MW Hydroelectric Power Plant: Penstock Replacement
A steel pipe replacement of a 70 inch wood stave penstock was designed and constructed.  It supplies water to the 10MW turbine generator located at the Danville Power & Light Pinnacles Hydro Complex.



6MW Hydroelectric Power Plant: Power Uprate
The uprate of an existing hydroelectric facility was designed, including new turbines and housing, new head gate structure and new intake structure.



20MW Peaking Plant: Preliminary Design
Preliminary design was completed for the site slope stability, foundation and a cooling water supply study for a FPL peaking plant adjacent to the James River. The study included a seven mile pipe routing plan, pumping system and construction cost estimates.
