University Steam Boiler/Heat Exchanger Replacement

Our client, a university in eastern Canada, operates a 4 boiler plant with a boiler/heat exchanger combination. The boiler, operating at 175 PSIG, generates steam that is used in the heat exchanger to heat up hot water in a closed loop system. This unique hot water distribution network is one of only two similar systems in Canada. The boiler was designed with no feedwater pump and condensate from the heat exchanger goes directly back into the boiler.

Bacon Engineering was tasked with replacing one of the four boilers and integrating the new boiler into this unique set-up. We added a control strategy to the economizer which increased its efficiency by utilizing high temperature hot water (HTHW) instead of feedwater. The client was so pleased with the first unit that they have since ordered a second boiler.
