Flow Control Devices for Mechanical Draft Fans

Flow Control Devices for Mechanical Draft Fans

Comparing Different Flow Control Devices for Mechanical Draft Fans   Mechanical draft fans are integral parts of a plant’s operations. They are essential to moving large amounts of air and gases through a system duct and components, but they use a large amount of power… read more

Anatomy of a Coal to Biomass Conversion

Anatomy of a Coal to Biomass Conversion

In 2011, ReEnergy Holdings LLC acquired the Black River Generation facility at Fort Drum, the home of the Army’s 10th Mountain Division near Watertown, NY. The Albany-based company had plans to convert the decommissioned coal-burning power plant into a biomass-fed powergeneration facility that would supply… read more

Optimize Your Kiln ID Fan

Optimize Your Kiln ID Fan

Industrial fans are crucial to the efficient performance of plants of all sizes, from power plants to steel mills and pulp & paper mills. The importance of their job – to direct the flow of air and gases – cannot be overstated. A well-designed, well-maintained… read more

Common Sense Solutions to Minimize Emissions

Every plant manager wants their plant to function at the highest level of productivity possible while complying with emissions regulations. This article documents common problems that reduce biomass systems’ efficiency and offers straightforward ideas for solving them. Topics covered include biomass fuel delivery, boiler air… read more

Right Sizing Mechanical Draft Fans

Right Sizing Mechanical Draft Fans

Mechanical draft fans are some of the largest parasitic loads in any production process. More often than not, existing fans are improperly engineered for peak efficiency due to the designer’s fear of creating a system limited by fan draft. Cost-effective modifications to these fans can… read more

Decoding “Efficiency” for Mechanical Draft Fans

Efficiency is an important topic in mechanical draft fan engineering, as well as process engineering more broadly. Currently, there are many different types of fan efficiency ratings prevalent in discussions of draft fan engineering, but these ratings are rarely compared side by side and assessed… read more

Optimizing Fans for the Escalante Generating Station

ProcessBarron was contracted to retrofit two aging fans at the Tri-State Generation and Transmission Association’s Escalante Generating Station in Prewitt, New Mexico, with more efficient designs, rather than an in-kind swap out. The existing fans needed to be replaced because of age, and in-place tests… read more

Computational Fluid Dynamics

Computational Fluid Dynamics (CFD) are an effective way to assess the viability of a fan installation. A form of computer simulation, CFD is much less expensive than scale model testing and provides an opportunity to test design variations iteratively in a virtual environment so that… read more
