03580 CHEMICAL CLEANING HRSG'S TOP 10 11 LESSONS LEARNED

Product Number: 51300-03580-SG

ISBN: 03580 20003 CP

Author: John McGraw, David Fawcett

Publication Date: 2003

$20.00

The approach to the commissioning of a heat-recovery steam generator in the industry has varied from project to project. One school of thought contends that no chemical cleaning (or minimal) is required. The second school of thought contends that a complete chemical cleaning is required. This report discusses these differences, and a properly designed and well executed cleaning with desired results.

06536 CORROSION EFFECTS FROM HIGH IRON CONCENTRATION IN ALKALINE CHELANT BOILER CLEANING

Product Number: 51300-06536-SG

ISBN: 06536 2006 CP

Author: J. W. Horvath, J. F. Harvey

Publication Date: 2006

$20.00

If the iron concentration in an alkaline chelant boiler cleaning solution reaches a high value when dissolving magnetite, it sometimes continues to increase rapidly and not level, indicating corrosion of the boiler metal. A laboratory study of “runaway iron increases” investigated the cause and the best mitigation methods.

Case Study of the Premature Coating Failure on the Boiler Tubes

Product Number: 51324-21187-SG

Publication Date: 2024

Boiler tubes in the penthouse portions are meant to extract the heat from the flue gases. The tube material and coatings on the boiler tubes are generally selected to mitigate the high-temperature oxidation and other metallurgical damage mechanisms. Tubes are not designed to experience aqueous corrosion from the external environment. For these reasons, boilers are designed and laid out in a fashion to limit the ingress of moisture and corrosive ions from external sources such as wind, cooling tower drift, etc. This paper addresses the case study on the failure of primer coating on the boiler tubes from the upset condition that allowed the flooding inside the penthouse leading to aggressive corrosion on the tube skin. This paper also discusses the multiple corrosion modes observed and their associated mechanisms followed by recommending corrective measures. Finally, the paper addresses the contribution of insulation material in heterogeneous corrosion morphologies.

Recovery Boiler Tube Failure by Mechanisms of Stress-Assisted Corrosion and Phosphate Hideout

Product Number: 51315-6059-SG

ISBN: 6059 2015 CP

Author: Max Moskal

Publication Date: 2015

$20.00

This paper presents an unusual case example of recovery boiler waterside tube deterioration by a combination of SAC and phosphate hideout corrosion mechanisms. The case shows boiler tubes that exhibited through-wall corrosion and cracking.

TR46107-2020 “Control of Corrosion, Deposition, and Microbiological Growth in Heating, Ventilation, and Air Conditioning Recirculating Water Systems in Buildings”

Product Number: TR46107-2020

Publication Date: 2020

$109.00

This technical report applies to water-using cooling and heating systems in buildings. It provides information for minimizing system damage and operational interference because of corrosion, scale, fouling, and microbiological growth in building heating, ventilation, and air conditioning (HVAC) systems. This includes open and closed circulating water systems, low-pressure steam boilers and hot water “boilers.” The document also addresses thermal energy storage systems, but does not address potable water or fire protection systems. It is intended for use by building owners and engineering, maintenance, and operations management personnel. It is also intended for use by those involved in the design and construction of building HVAC systems so that corrosion, scale, fouling, and microbiological growth problems described above can be understood, anticipated, and minimized through appropriate design decisions.

Tracer Studies in Boiler Scale and Corrosion Control

Product Number: 51323-19005-SG

Author: Haiping Lu, Swamy Margan, Dean Diagostine

Publication Date: 2023

$20.00

Boilers are one of the most fundamental systems in refineries or processing plants. It is very critical to assess and control the conditions of boilers to avoid the operation failure. Scale and corrosions are major problems in the boiler. Boiler chemical treatment has been considered to be a cost-effective approach to prevent deposition formation and minimize corrosion in boilers to control feeding chemicals, tracers are used for monitoring chemical dosage levels. The usage of fluorescent tracers for dosage control and system diagnostics is a recognized approach for decreasing operator workload and improving system performance.
