1.2. External Combustion Sources

Try these first

1. 1.

   Define emission factors.

   Hint

   Think of it as a measure of pollution per fuel type.

2. 2.

   What is the difference between external combustion sources and internal combustion sources?

   Hint

   Consider examples of engines versus power plants.

3. 3.

   What is an emission factor?

   • A measure of the amount of fuel burned
   • A quantitative estimate of pollutant emissions
   • A type of combustion technology

   Hint

   Think about pollution measurements.

4. 4.

   True or False: Fugitive emissions are planned emissions released from a process.

   • True
   • False

   Hint

   Consider the definition of 'fugitive'.

5. 5.

   A plant uses bituminous coal and fluidized bed combustors. Analyze how switching entirely to fluidized technology could affect NOx emissions.

   Hint

   Consider how the burning process influences emissions.

6. 6.

   Fugitive emissions are being measured at a gas facility. Discuss methods that could be used to estimate these emissions.

   Hint

   Think of ways to detect leaks in industrial equipment.
