What is boiler modulation and boiler cycling? - HeatGeek

The graph above from Viessmann illustrates quite well the increase in efficiency from modulating the boiler even from non-condensing boilers. However you will notice there is a drop in efficiency once the output reaches less than 5% modulation or 1/20th of the modulation. Well go further into the reasons for this at the end of the article.

Main Condenser - Steam Condenser | Description | nuclear ...

The main steam condenser (MC) system is designed to condense and deaerate the exhaust steam from the main turbine and provide a heat sink for the turbine bypass system. The exhausted steam from the LP turbines is condensed by passing over tubes containing water from the cooling system. There is a main condenser unit under each LP turbine usually below the turbine with its axis perpendicular to the

How Condensing Boilers Work - Plumberparts

The flue temperature will be around 55 degrees celsius. That means up to 200 degrees of heat is being transferred to your heating water not expelled into atmosphere. This means you save loads of money. Condensing boilers do not condense all the time only when the return water temperature is low enough.
