Steam Boiler: Boiler Efficiency Calculation

Heat loss due to dry flue gas is the heat loss which is contained in dry flue gas such as CO2, O2 and N2. These gases are one of causes of heat loss in combustion process. The high temperature of flue gas coming out from boiler affect amount of heat loss.

MAXIMUM ENERGY GAIN FROM FLUE GASES

Example #1 - Determination of the Flue Gas Temperature from a Natural Gas Furnace In this specific example the combustion device is an older lower efficiency Natural Gas Home Furnace. The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3 ), the fuel consumption is 100,000 Btu/hr (HHV Basis), and the heat delivered to the home is 80,000 Btu/hour.

Stack Losses for Natural Gas - NRCan

The dry flue gas loss (L DG) can be reduced by reducing the amount of dry flue gas (DG) and by reducing the difference between flue gas temperature (FGT) and combustion air temperature (CAT). DG can be reduced by reducing the excess air‚ but only up to a point; insufficient excess air leads to increased emissions of C O and hydrocarbons‚ even a risk of furnace explosion.

why do we keep exhaust gas of boiler in minimum …

The goal is to create conditions that generate the smallest possible amount of flue gas (exhaust gas that is expelled) at the lowest possible temperature. This results in increased boiler efficiency. Think about it; the boiler draws in cool air, heats it up, and sends it out the stack.

Boiler Combustion | CleanBoiler.org

An induced flue gas recirculation package can lower NOx levels by reducing flame temperature without increasing CO levels. CO levels remain constant or are lowered because the flue gas is introduced into the flame in early stages of combustion and the air fuel mixing is intensified.
