  • HARVARD BLACKSTONE – BOILER 11 UPGRADE

    < Back to all projects HARVARD BLACKSTONE – BOILER 11 UPGRADE DESIGN START/COMPLETION: November 2010 – June 2011 SIZE & TECHNOLOGY: 150,000 lb/hr dual fuel (natural gas and #6 oil), 400 psig steam boiler IN-SERVICE: November 2012 FIRM ROLE: EPC (Engineering, Procure, Construct), Commissioning In 2003, Harvard purchased the Blackstone Station in Cambridge, MA from NSTAR to insure a secure source of steam to serve the future campus expansion. Waldron was retained to provide technical due diligence for the purchase as well as develop a plan for Blackstone that would meet the Campus growth needs into 2020. The installation of Boiler 13 was the first step in the plan. After the successful installation of Boiler 13, the next step was the Boiler 11 upgrade. Waldron was once again brought on as the EPC contractor by Harvard University for the project. The project scope included an upgrade of the fuel delivery and control systems associated with Boiler 11 at Harvard’s Blackstone steam plant in Cambridge, MA. The proposed work involved a 150,000 lbs/hr dual fuel (natural gas and #6 oil), 400 psig steam boiler burner management and combustion control systems complete replacement. These upgrades modernized the fuel train and combustion controls for the industrial boiler which provides part of the Harvard campus steam supply.

  • GENERADORA ELECTRICAL DEL NORTE

    < Back to all projects GENERADORA ELECTRICAL DEL NORTE LOCATION: Puerta Barrios, Guatemala SIZE & TECHNOLOGY: 5.8 MW Turbo Expander, Super Critical Propane, Cycle Evaporative Cooling DESIGN START: Fall 2012 IN SERVICE: Spring 2013 SCHEDULE: Construction Start Winter 2013, Construction Complete Summer 2013 FIRM ROLE: Engineering, Procurement Generadora Electrical Del Norte (Genor), a Guatemalan independent power producer, owned a 40 MW heavy fuel oil-fired reciprocating engine plant in Puerto Barrios, Guatemala. Recognizing the benefits of an improved plant heat rate, Genor under-took an analysis of ways to improve the output and efficiency of the Puerto Barrios facility. A number of options were analyzed to “combine cycle” the plant. The plant selected the Organic Rankine Cycle ORC-AT, as designed by Waldron. Waldron has an exclusive license agreement to design and construct the ORC-AT cycle. The cycle consists of a two-stage heat recovery system producing supercritical propane from exhaust waste heat. Energy in the propane is converted to shaft horsepower in a two-stage turbo expander coupled to a single generator via a common gearbox. Heat from exhausted propane is recuperated against propane prior to recycling to the superheater. Cooling for the cycle is via a bank of evaporative condensers. The plant will produce a net output of 4.0 MW for sale to the grid with the addition of no fuel input.

  • UMASS POWER PLANT & DISTRIBUTION INFRASTRUCTURE SYSTEM STUDY

    < Back to all projects UMASS POWER PLANT & DISTRIBUTION INFRASTRUCTURE SYSTEM STUDY LOCATION: Worcester, MA START: Fall 2018 COMPLETION: Spring 2019 FIRM ROLE: Engineering Consultant Waldron has been working on projects on the UMass Medical School Campus for over 20 years. The goal of this power plant and distribution infrastructure system study was to develop the most effective solution from a life cycle perspective to meet the evolving needs of the campus over the next 20—30 years. The three utilities that were studied included electric, steam and chilled water. As part of this project, Waldron performed an assessment of existing equipment and infrastructure, reviewed the current operating strategy, developed a conceptual upgrade to the campus metering scheme, and reviewed over twenty capital projects for their potential benefits to the system. For each of these capital projects Waldron conceptualized a project approach, calculated the life cycle outcomes for the campus using an 8,760-hr utility model, developed capital cost budgets for each, and also reviewed the level of urgency and environmental impacts of each. The project included hydraulic modeling of the steam and chilled water distribution systems, modeling of the electrical distribution system, and development of an 8,760-hr utility model with dispatch algorithms for the combustion turbine, three steam turbines, boilers and chillers within the UMMS facility. These models enabled investment grade accuracy for the life cycle cost analysis associated with each of the capital upgrades that were considered for the facility.

  • UNH PROCESS LANDFILL GAS PROJECT

    < Back to all projects UNH PROCESS LANDFILL GAS PROJECT LOCATION: Durham, NH IN-SERVICE: 2009 SIZE & TECHNOLOGY: 7.9 MW Turbine/HRSG duct-Landfill gas/natural gas blend FIRM ROLE: Engineering and Design Waldron Engineering was contracted by EMCOR to design the installation of a landfill gas to energy system for the existing Siemens gas turbine and a HRSG duct-burner for the University of New Hampshire. Waldron was the Engineer of Record for the process landfill gas (PLG) project and assisted with work on the aspects of the landfill gas conditioning. The landfill gas is conditioned and blended with natural gas for the operation of the cogeneration facility. Waldron was responsible for providing a construction package that defined the work for the mechanical, civil, electrical and controls portions of the work. The construction specifications for the work were provided as part of the package. All the specs were coordinated with the existing UNH equipment and materials to maintain the consistency of the equipment in the plant. The UNH Cogeneration Plant consists of a 7.9-megawatt dual-fuel combustion generator train, including a HRSG (heat recovery steam generator) with a duct burner that produces 100,000 pounds of steam per hour and a 1,200-ton chilled water plant.

  • MILFORD REGIONAL MEDICAL CENTER MICROGRID

    < Back to all projects MILFORD REGIONAL MEDICAL CENTER MICROGRID LOCATION: Milford, MA DESIGN START: January 2015 SIZE & TECHNOLOGY: 800 kW Reciprocating Engine IN-SERVICE: December 2015 FIRM ROLE: Engineering, Construction, Commissioning The installation of a new combined heat and power (CHP) system at the Milford Regional Medical Center was executed as a fast track project by Waldron. Milford was looking for cost savings and resiliency for their campus. The new CHP system included a packaged 800 kW natural gas fired Caterpillar engine and waste heat recovery. Heat from the jacket water system and the engine exhaust are utilized to produce 15 psig steam for the hospital low pressure system. Energy from the engine lube oil system was recovered and utilized for the domestic hot water system. The CHP system will provide operational cost savings and in the event of a power outage, could supplement the emergency diesel engines to provide power to the hospital. The project was completed in 10 months, from notice to proceed to utility acceptance testing. 600 kW and 600 kWh Energy Storage System (ESS) operating in parallel with the existing CHP and utility. The ESS has the capability to black start the CHP and together can operate isolated from the Grid. With this new ESS addition, Milford Hospital established a highly resilient microgrid system with the option to add PV or other renewable generations. This project is endorsed by MA Dept of Energy Resource (DOER) Resilience Program. An economic benefit of ESS, is that it is able to do peak shaving to reduce the overall energy costs. Scope of work included: Construction Permitting Balance of Point—Detailed Design Review CAT Supplied Equipment Submittals Elevated Gas Permit Variance Construction Commissioning
