Brandon Shores Power Plant, Baltimore, Maryland

Air Pollution Control Services: Mechanical & Piping Systems Installations

The Industrial Facility Project

The air pollution control services project at Brandon Shores Power Plant is a major environmental upgrade which includes the air quality control systems installation of flue gas desulfurization (FGD) also known as wet scrubbers. This scrubber installation is part of Constellation Energy’s efforts to support Maryland’s Healthy Air Act. The installation of the scrubbers will reduce the sulfur dioxide emissions at Brandon Shores by 95 percent. The scrubbers include a new chimney stack at the Brandon Shores plant replacing two chimney stacks currently in existence. The scrubber will assist in eliminating emissions by passing the gases emitted in the process of burning coal through a tower in which a water and limestone mixture is sprayed. The sulfur dioxide in the flue gas reacts with the limestone to produce gypsum. The remaining water vapor rises in the form of steam from the stack.

Poole & Kent Mechanical Contractor Role

In our role as the mechanical contractor, Poole and Kent is responsible for the installation of the mechanical systems consisting of 80 work packages to include plant air, control air, oxidation air, make up water, hydrocyclone piping and missed eliminator systems to name a few. Some processes of the 80 mechanical system installations require Poole and Kent to install piping systems ranging in size from ½” to 30” pipe including carbon steel, fiber glass piping, rubber lined piping and stainless steel piping.

Challenges / Achievements / Goals

A fast-track project schedule is a challenging aspect of this mechanical construction project. To accommodate the project schedule and staging of the project, Poole and Kent has overseen 150 employees working 2 shifts consisting of 10 hours per day for a minimum of 5 days per week. This shift work ensures the project remains on schedule.
