Flue Gas. Flue gases are a mixture of combustion products including water vapor, carbon dioxide, particulates, heavy metals, and acidic gases generated from direct (incineration) or indirect (gasification and pyrolysis) oxidation of RDF or intermediate syngas. From: Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2017

flue-gas stack - wikipedia

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

However, it is noted that the flue gas volume per unit of supplied energy, S (m3/MJ), is essentially invariant for a given fuel type and this is a better basis for calculation when compared with the flue gas volume per unit mass. The flue gas volume is derived from the

Unit 12 - Chapter 52 - Firetube Boilers Flashcards | Quizlet

In a packaged firetube boiler, the flue gas velocity within the unit is maintained by: 1) Increasing forced draft fan speed 2) Constructing a taller stack 3) Varying the number of firetubes 4) Varying the firetube diameters 5) Decreasing forced draft fan speed.

Flue Gas Flow Rate - AWE International

The tracer dilution method directly determines the flue gas flow rate and does not, therefore, require the cross-sectional area to be known. A tracer is injected into the flue gas, for a short period of time, well upstream of the flue, so that the tracer is intimately mixed with the flue gas.

If the boiler fuel contains Sulphur (and most do) combustion products in the flue gas will include Oxides of Sulphur (SO2 and SO3). SO3 combines with water (H2O) to make Sulphuric Acid (H2SO4).

Controlling CO boilers

Jul 01, 2011· The steam output from the boiler becomes a dependant variable tied to the input requirements necessary to ensure complete combustion of the CO in the flue gas stream. While the CO content of the flue gas stream from the FCC unit may vary rapidly and considerably over time, the total mass flow of the flue gas stream is relatively constant and

This is a measurement of the flue gas velocity through the boiler. If the draft is excessive, it could pull the flue gases through the boiler too quickly, lowering the efficiency of the boiler. If the draft is too low, damage could occur to the burner.
