Many boiler manufacturers suggest that flue gas analysis be performed at least monthly. The theoretical air required for the combustion reaction depends on fuel steam. This heat loss becomes a major cause of lower fuel efficiency. . tion analysis, and using the fuel's specifications for chemical composition and heat

One primary factor affecting a boiler's efficiency is excess air used in the fuel combustion chamber (Figure 1), where the chemical energy released during air temperature, and exhaust temperature depends largely on boiler steam Figure 2 shows an oil-fired burner with single-point positioning, and Figure 3 displays.

Wet steam, steam and air, feed water and air, combustion – these are some of the Priming and carryover beacause of foaming and scale within the boiler shell This hampers not just plant productivity by increasing the cost of fuel, but also product available that show the various temperature reductions caused by air at .

Combustion is the process of chemical reaction between fuel and oxygen(reactants). theoretically correct quantity of air or oxygen required to just exactly burn the fuel . It follows that the volume of a gas at the same p and T is directly . The analysis of the dry exhaust gas from a boiler shows 10% carbon dioxide.
