Which of the following practices enhances boiler efficiency?

Implementing scheduled maintenance and operational checks is essential for enhancing boiler efficiency. Regular maintenance ensures that all components of the boiler system are functioning optimally, minimizing energy waste and preventing potential breakdowns. By routinely inspecting and servicing the boiler, issues such as scaling, leaks, or blockages can be identified and addressed before they lead to inefficiencies.

Operational checks also involve monitoring performance metrics such as pressure, temperature, and fuel consumption, which can help in fine-tuning the operation of the boiler for peak efficiency. This proactive approach not only extends the lifespan of the boiler but also ensures that it operates within the designed parameters, leading to improved energy efficiency and reduced operational costs.

Other practices, such as using untreated feedwater or neglecting maintenance, would lead to various operational problems, such as build-up of minerals or corrosion, which degrade efficiency. Similarly, infrequent water testing could result in undetected issues that compromise the boiler's performance, thus not contributing to efficiency improvements.
