What is boiler modulation and boiler cycling? - HeatGeek

1/11/2018 · When the boiler refires it will do a quick 'post purge' to clear any products of combustion from the burner chamber before firing, as well as running the pump again wasting energy. Even when the fan is not running and the pump is in overrun (typically 2-5 mins) the boilers heat exchanger is warm/hot, and because the 4" flue is nearly always above the heat exchanger simply leaks heat outside.

Full modulation, however, means that the boiler keeps firing over the whole range to maximise thermal efficiencyand minimise thermal stresses. This type of control can be fitted to any size boiler, but should always be fitted to boilers rated at over 10 000 kg/h.

Grate firing - Wikipedia

24/10/2015 · Firing rate is a function of Boiler Load or in other words, Steam Load demand governs the load of the boiler and fuel firing. If you see the typical (almost the same for all the boiler brands)firing rate logic on the boiler instrumentation line diagram, the signal for firing command is initiated by the steam pressure controller, also called master control.

Turndown ratio - Wikipedia

Turndown ratio refers to the width of the operational range of a device, and is defined as the ratio of the maximum capacity to minimum capacity. For example, a device with a maximum output of 10 units and a minimum output of 2 units has a turndown ratio of 5. The term is commonly used with measurement devices and combustion plant like boilers
