What should be regularly monitored to prevent issues associated with oxygen in a boiler?

Monitoring water quality is crucial in preventing issues associated with oxygen in a boiler because oxygen can cause significant corrosion of the boiler’s components, leading to potential failures and costly repairs. Maintaining optimal water quality involves controlling the levels of dissolved oxygen and other impurities in the water. Proper treatment, like deoxygenation and the addition of chemicals to remove or prevent oxygen from dissolving into the water, is necessary to protect the integrity of the boiler system.

While other choices, such as fuel consumption levels, boiler output pressure, and external temperature, are important for the efficient operation of a boiler, they do not directly address the corrosive effects of oxygen. Fuel consumption deals with the efficiency and cost of operation, output pressure relates to the performance of the steam or hot water, and external temperature can affect thermal efficiency but none specifically focus on the prevention of oxygen-related problems in water quality. Thus, ensuring high water quality directly addresses the risks posed by oxygen in a boiler system.
