Flue gas composition is significantly affected by the combustion conditions. Concentration of gaseous species upon firing 1.7% S coal (chemical composition is given in Table 1) was calculated at 1300 °C, assuming thermal equilibrium, and presented in Figure 2 as a function of air–fuel ratio. In this chapter, air–fuel ratio is defined by the ratio of their weights; air–fuel ratio of 10

2010-11-3 · Flue gas is confined to the boiler and flue gas ductwork and generally poses no hazard. In some types of boilers and associated gas ducts, however, flue gas is at a higher pressure than the surroundings and can leak into occupied areas.

The excess or reserve air affects the volume of flue gas by increasing it proportionately. Figure 1 shows the effect this has on the percentages of OXYGEN and CARBON DIOXIDE. Remember, as the excess air is reduced, the percent of extra oxygen decreases but the percent of carbon dioxide increases.

The flue temperature of oil equipment even with a flame retention burner should be a minimum 300 degrees higher than what you are heating in most cases. Oil flame temperatures are 1000 degrees hotter than gas flames therefore the flue temperatures can not be the same and rarely should they ever be below 400 degrees.

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

How stoichiometric air-fuel ratio is calculated. In order to understand how the stoichiometric air-fuel ratio is calculated, we need to look at the combustion process of the fuel. Combustion is basically a chemical reaction (called oxidation) in which a fuel is mixed with oxigen and produces carbon dioxide (CO 2), water (H 2 O) and energy (heat). Take into account that, in order for the

2018-12-19 · The gas supply to the boiler and cooker was renewed and the gas fire turned off and disconnected. The company said there were at least two gas leaks - one which they found - in the cavity wall because a pipe was missing important sleeving and one other they could not locate and thought it could be buried in the floor and therefore inaccessible.
