Video: How Demers Greenhouse is heated during Quebec's harsh winters
The pumps draw hot water from the bottom of the greenhouse's 2 million litre hot water storage tank (at a temperature range of 40 - 45°C), which is circulated up to the main greenhouse heat exchanger (HX-6) located 900 meters away inside Waste Management's 8 MWe Landfill Gas Renewable Energy Plant. The heated greenhouse water then exits HX-6 (at a temperature range of 80 - 90°C) returning back to the greenhouse, discharging into the top of the storage tank.
Vito Casola, P.Eng., President at POWER GENySYS, was responsible for the complete conceptual and detailed Engineering, design/drafting, equipment procurement, project and construction management/supervision, and commissioning for integrating heat recovery equipment at Waste Management's 8 MWe Landfill Gas Renewable Energy Plant in Drummondville, Quebec.
The project included the recovery of 8.4 MW of thermal energy from the power plant (in the form of 190°F hot water) all transferred to the heating system of a new 3.2 hectare greenhouse (via a 1.8 km district heating pipe loop) and integrated with its' 2 million litre hot water storage tank.
