The boiler pressure is maintained at the top of its control band, and the level of stored energy is at its greatest. Should more energy be required at short notice, the control system can immediately respond by increasing the firing rate, without pausing for a purge cycle. Disadvantages of a modulating control system: Most expensive. Most complex.

This causes the boiler to run hotter all year round in order to quickly respond to room temperature changes. Running hotter means burning more fuel and higher heating bills. In addition, most condensing boilers have no thermal purge cycle, reducing condensing operation. The lack of a thermal plunge causes the unit to finish hot, wasting energy

Why do you purge a boiler before ignition?

Accordingly, what is the purge cycle on a boiler? Purging is like opening the window on your furnace to let air in. It is required by the NFPA86 and should be done before each furnace heating system start-up. The purge of airflow removes gaseous combustibles in a furnace and replaces it with air.

boiler. This is done with the following simple equation: Stack Losses= m (h out-h in) When operating the boiler at any load, the unrecovered energy can be calculated through this equation. Prior to starting the burner, the pre-purge cycle requires the fan to push at a minimum 4 air changes through the furnace. During this time there is no

Stop Wasting Money, Reduce Boiler Cycling - WC Rouse

In the pre-purge, the fan operates to force air through the boiler to flush out any combustible gas mixture that may have accumulated. The post-purge performs a similar function. During purging, heat is removed from the boiler as the purged air is heated. Example A 1,500 horsepower (hp) (1 hp = 33,475 Btu/hr) boiler with a cycle efficiency of

Boiler Efficiency - an overview | ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Post Purge — Heating Help: The Wall

The 7184 purge circuit must have been damaged somehow as it was not purging. I set the purge so it would drop my flue gas temp to 200 and then shut down. Boiler manual claims this sufficient for post purge. I will check it again as we get out of the shoulder season and adjust the purge cycle downward if needed. Thanks again to all for the help.
