USING BOILER FLUE TEMPERATURE TO CALCULATE

Flue gas heat losses are divided into two parts; the heat content of the dry flue gases and the [latent] heat content of the water from combustion.” And, continuing, “The most effective guide to the rate of fouling is the increase in the flue gas temperature.” In boilers, fuel, gas or oil, is burned in air.

Boiler size and gas tank size - what's the ideal relation

Jul 24, 2012 · After what I could find out so far, the ideal relation between centre flue boiler and gas tank volume, so that the gas lasts long enough to boil most water, but runs out before the boiler is empty, is between 4:1 and 3:1. If anybody can provide more data, we could see if it is between these figures or not.

Boiler (power generation) - Wikipedia

The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.
