Which measure is often used to improve boiler efficiency?

Insulating the boiler and piping is a crucial measure for improving boiler efficiency. This is because good insulation helps to minimize heat loss from the boiler and its distribution system. When heat is retained within the system, less energy is required to maintain desired temperatures, leading to more efficient operation. Insulation prevents heat from escaping, thereby ensuring that more of the generated heat is used effectively in the heating process or in generating steam. This can result in reduced fuel consumption and lower operating costs, contributing to overall efficiency.

In contrast, lowering the water temperature may lead to inefficient heating cycles, increasing the energy required to reach optimal temperatures. Increasing the steam pressure can yield higher efficiency in some contexts, but it may also necessitate more energy to operate and could risk damaging equipment if not properly managed. Decreasing fuel quality often leads to incomplete combustion and higher emissions, adversely affecting efficiency and operational safety.
