What is the role of moisture formed in the burning of hydrogen in a boiler?

The moisture formed during the burning of hydrogen in a boiler primarily acts as a heat loss factor. When hydrogen combusts, it reacts with oxygen to form water vapor, which is a byproduct of this reaction. This water vapor can absorb heat that would otherwise be available for raising the temperature of the steam or water in the boiler system. As a result, the presence of moisture can lead to decreased thermal efficiency because it represents energy that is not fully utilized for productive work in the boiler.

This heat loss can lead to the need for additional fuel to maintain the desired steam output or temperature, thus affecting the boiler’s overall efficiency. While moisture does play a role in combustion and emissions, its formation in this context is primarily linked to the loss of heat that could contribute to better boiler performance.
