The Montreal Olympic Park is a source of national pride and includes the Olympic Stadium, a 541 foot (165 meters) observation tower and The Biodome. In 2015, the Park began a $6.5 million energy retrofit that reduced the energy bill by $ 1.55 Million. The project went on to win first place in the existing public assembly category of the 2019 American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) Technology Awards. The work lasted three years and four major projects were on the program:
Refurbishment of the thermal power plant
Conversion of the steam heating network into a hot water network
Optimization of ventilation
Installation of LED lighting
Ecosystem partnered with ENERVEX to apply a boiler heat recovery system as a part of this project.
The Challenge
design a heat recovery system with an impressive payback
design an energy efficient heat recovery system to meet varying demands
improve boiler efficiency
cut down on energy consumption
The Solution
A new ENERVEX VHX6400-66 flue gas heat recovery system from ENERVEX was installed on the stack of the primary boiler boosting the boiler's efficiency to 89%
A TDF 685 mechanical draft control system was applied to heat a low temperature water loop
Solution results in significant annual energy savings
Recovers an estimated 4,300MBH of energy off a single 45,000MBH boiler
