Measurement of CO2 in Flue Gases

Gas/Water Out Bubbling tube Gas In Water Jacket 1. Sampling Group A sampling probe is necessary for each point in the flue at which CO 2 is to be measured. For oil-fired boilers this may simply comprise an open-intake pipe in the flue attached to the sampling-line at its outer end, but for coal-fired boilers a soot filter is always necessary.

The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam. In other units, the flue gas is exchanged with boiler feed water to produce steam via the

Possibilities for reconstruction of existing steam boilers

Here is a guide to understanding the results from testing appliances with a flue gas analyser: Domestic Boilers and Hot Water Heaters. Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance.

Flue Gas - an overview | ScienceDirect Topics

In a positive pressure (PP) flue, exhaust gases are driven by a combination of pressure from fans inside boilers, expansion due to combustion and the buoyancy imparted to them by the residual heat of combustion. A negative pressure (NP) flue is a heat engine that propels the exhaust upwards using the buoyancy of the residual energy of combustion. The heat energy in an NP flue has expanded the …

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
