CSIA CHAPTER 2 || Verified for Accuracy.
What is the rapid oxidation of fuel resulting in the release of energy, usually in the form of heat
and light? correct answers Combustion.
Combustion efficiency is dependant on what 3 factors? correct answers Turbulence,
Temperature, and Time.
Define Turbulence. correct answers The mixing between air and wood in the combustion zone.
Define Temperature. correct answers The minimum ignition temperature that must be maintained
if combustion is to start and continue.
Wood fuel is a carbohydrate composed of what? correct answers Carbon, Hydrogen, and Oxygen
atoms.
Smoke that condenses in a venting system is called what? correct answers Creosote.
true or false: it is necessary to dry a piece of wood all I wants to move to the next stage of
combustion? correct answers false
What are the 3 stages of burning wood. correct answers Stage 1 - Drying, Stage 2 - Pyrolysis,
Stage 3 - Charcoal.
Define Stage 1 - Drying. correct answers When moisture is driven from the wood so that it can
be made hot enough to break up into its combustible components and burn.
Define Stage - 2 Pyrolysis. correct answers Wood molecules breaking down.
, what is the third and final stage of the combustion process? correct answers charcoal
Define Charcoal. correct answers Gases and tars removed from wood.
Perfect wood combustion yields only what? correct answers Carbon Dioxide, Water, and the
Release of Heat.
What 3 conditions must be favorable within the combustion area for combustion to be complete?
correct answers 1.)Sufficient heat to maintain the breakdown of wood molecules into
combustiable hydrocarbons. 2.) Sufficient available oxygen mixing with those hydrocarbons to
sustain this reaction. 3.) Adequate supply of fuel.
Define Creosote. correct answers Natural by-product of burning wood. Combustible deposit that
originates as condensed wood smoke, including tar, vapors, and other organic compounds.
Define Soot. correct answers Soot is what is formed in yellow -orange flames as the result of
unburned carbon particles leaving an active flame.
Define Latent Heat. correct answers The amount of energy in the form of heat released or
absorbed by a chemical substance during a change of state.
What are 2 types of Latent Heat? correct answers Fusion (Melting), Vaporization (Boiling)
What 3 factors affect creosote buildup? correct answers Smoke Density, Average Flue Gas
Temperatures, Residence Time.
the temperature of the gas is moving through the chimney flue is called the _____. correct
answers flue gas temperature
Define Smoke Density. correct answers The amount of unburned hydrocarbons in the flue gas.
