MONTREAL, Feb. 7, 2013 /CNW Telbec/ - Sofame Technologies is pleased to
announce that its novel Heat Recovery System will lower energy costs
and reduce carbon emissions, contributing to a truly healing
environment at the new McGill University Health Centre hospital in Montreal. As a public institution and a member of the
community, it is important to the MUHC to make sure that both patients
and the environment receive the care and respect they deserve.
When Montreal-based distributors, Enviroair, met the consulting engineering firm to discuss plans for the new
2.4-million sq. ft. MUHC Glen site, one of the priorities was to
determine how best to maximize heating efficiency while ensuring the
lowest possible energy costs. The stated objective was to achieve a
solid 20% in yearly energy savings, results that will be measured after
the startup, and this is precisely what the team was aiming for.
The answer to their energy performance and cost savings requirements was
found through Sofame Technologies, a Montreal company which is a pioneer in industrial heat recovery from
boilers and turbine exhaust. In fact, the unit chosen was the very
same type of direct-contact stack economizer used by numerous other
hospitals to achieve up to 98% heating efficiency. A Percotherm®
direct-contact stack economizer, designed and manufactured by Sofame in
Quebec, would be linked to the hospital complex's three hot water
boilers and three steam boilers, and integrated seamlessly in the
sophisticated climate control system. At thirteen feet in diameter and
serving MUHC Glen site's 3,800 horse power boiler capacity, this
Percotherm® would be one of the largest in Canada.
According to the consulting engineering firm, long before the start-up
of construction, it was understood that every decision pertaining to
equipment for the power plant had to be based on proven performance and
long-term, glitch-free durability.
The Percotherm® direct-contact stack economizer recuperates the residual heat contained
in a boiler's flue gas and transfers the heat to a cold water stream.
Hot water is produced at temperatures as high as 140 degrees F (60
degrees C). Cool water enters the unit at the top and is then uniformly
distributed over the upper chamber through a layer of stainless steel
nodules which constitutes the heat transfer zone. The water percolates
down through the packing where in comes into "direct-contact" with the rising hot products of combustion. Both the sensible and the
latent heat contained in the gases are transferred to the water.
The system designed includes three dampers, one induced draft fan, one
variable speed drive, plus a state-of-the-art computerized control
panel with operator touch screen. The first firing of the boilers is
scheduled for spring 2013.
Adds Luc Mandeville, Sofame's Vice-President of Technology, "Without a
doubt the Percotherm® will deliver the environmental performance that
the MUHC's Glen site is counting on, and also significant operating
cost savings. We have custom-manufactured dozens of similar units and
performance reviews are invariably outstanding."
MUHC's Glen site will adhere to stringent environmental standards (LEED®
Silver certification and BOMA BESt) and favour sustainable development, energy savings, healthy air flow, efficient water use, waste
reduction, recycling and green operations. Sofame, with the
installation of its novel heat recovery system to lower energy costs
and carbon emissions, is proud to contribute to the high environmental
standards at the Glen site.
