B&W Awarded Contract for Boiler Refurbishment

(BARBERTON, Ohio – September 26, 2019) – Babcock & Wilcox Enterprises, Inc. (NYSE:BW) announced today that its subsidiary, The Babcock & Wilcox Company (B&W), has been awarded a contract for more than $12 million to refurbish a recovery boiler for a U.S. manufacturing facility.

B&W Expert Explains New Bottom Ash Technology in POWER Magazine

Submerged Grind Conveyance Technology

New environmental regulations have forced many coal power plant operators to consider alternative options for handling their boiler bottom ash.

Although mechanical drag systems can often meet regulatory requirements, space can pose problems and costs can be significant. An innovative grinder-conveyor design offers a number of advantages over more-traditional systems.

B&W engineer Tyler Little discusses advancements in ash handling and bottom ash conveyors in this month's issue of POWER Magazine: New Technology for Bottom Ash Conversion Emerges

CFB Boiler Upgrades at a Petrochemical Facility in Southeast Asia

Capacity Restoration, Reliability Improvement, NOx Reduction and SO2 Reduction of Existing Circulating Fluidized-Bed (CFB) Boiler
Restore Capacity, Improve Reliability, and Reduce Emissions

Immediately after operations of a new circulating fluidized-bed (CFB) boiler were turned over to the customer at a large petrochemical facility in southeast Asia, the unit began experiencing operational and maintenance issues. The boiler could typically run no higher than 70% MCR load.

B&W was called to conduct an extensive engineering review on this non-B&W boiler and determined that 100% MCR operating condition of the CFB boiler could be achieved by considering several key functional conditions and design fundamentals. Read how B&W’s upgrades resulted in the unit successfully reaching and continuously operating at full load capacity.

EPA's Affordable Clean Energy (ACE) Rule

Affordable Clean Energy Rule

The EPA’s recently published Affordable Clean Energy (ACE) Rule identifies heat rate improvements as the Best Source for Emissions Reductions (BSER) to control CO2. While the rule currently does not set limits, it establishes the framework for states to use to set achievable unit level heat rate improvements (HRI) at the plants.

We prepared an overview of the rule, summarized the timeline, and review the six BSER candidate technologies which can help you improve plant heat rate and boiler efficiency.

The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry
Successful long-term operation of steam-producing systems requires careful attention to water treatment and water chemistry control. Proper water chemistry control not only affects boiler operation by optimizing efficiency and reducing maintenance costs, it also can improve performance and life expectancy of other system components, including heat exchangers, pumps, turbines and piping throughout the steam generation and condensation cycle.

This article discusses steam purity requirements, water sampling and analysis techniques, and boiler feedwater limits.
