Montpelier District Heat Plant Breeching
The State of Vermont and the City of Montpelier joined forces on a project to make Montpelier’s Downtown area more energy efficient by installing two Biomass boilers and the relocation of an existing boiler. The two primary objectives of the project were to reduce operating costs for energy and minimize emissions.
New England Air was hired by a local contractor to fabricate and install the breeching for the two new woodchip boilers and the existing boiler. The breeching was fabricated out of 3/16” black Iron metal with roughly 1,900 linear feet of all welded construction. Approximately 18,495 lbs of metal was used on this project. All of the breeching is reinforced using structural angle. Anvil Slide assemblies were added to support the duct which provided for lateral and axial movement due to thermal expansion and contraction. Isolation/butterfly dampers with fabricated expansion joints were installed along with low point drains and emission test ports.
Upon completion this project will provide Biomass delivered steam to many state and city owned buildings and several non-government privately owned neighboring buildings.
Due to unforeseen project delay New England Air installed temporary breeching to a remote boiler located outside of the building to provide heat.
