Real time boiler efficiency using PTC method? - Boiler

2009-2-27 · The "powers that be" monitor our boiler efficiency and our current method uses the natural gas and steam flow meters. Due to very dramatic swings in steam load, we often have a boiler firing in it's low range (20% or below). The steam flow meters simply don't work at that range and I get calls asking why the boiler was 5% efficient yesterday.

Dynamic model of a bubbling fluidized bed boiler

Fluidized bed boiler Fluidized bed combustion was originally developed for combustion of coals with high sulfur content. The formed sulfur dioxides can easily be neutralized by addition of limestone into the bed [6]. The boiler is excellent for burning low value fuels and has a great advantage as it can burn several different fuels at once [6].

From a CFB reactor to a CFB boiler The review of

In a CFB boiler, the circulating system gradually accumulates a large amount of narrow-sized fine particles to form a fast bed in the upper furnace, as shown in Fig. 7. Consequently, the size of bed material in the dense bed is from 100200 μm to 12 mm. As a result, the amount of air to fluidize emulsion phase is much less than that in BFFB.

explanation of boiler efficiency curves examples in EP

Apologies for what is almost certainly a very dumb question but I'm struggling to understand what the boiler efficiency curves in the EP example files actually represent. Looking at InputOutput reference for the formula and plotting the biquadratic condensing boiler efficiency curve data given in the boilers.idf file gives Eff = 112% at 0.1 part load and Twater = 50oC for example.
