Copper (II) oxide is mixed with organic compound during combustion. The purpose is:
A. to reduce the economy of the process
B.
to carry out complete combustion
C. to reduce the time for completion of the
reaction
D. all of above
Answers
Waste storage and feed preparation.
Combustion in a furnace, producing hot gases and a bottom ash residue for disposal.
Gas temperature reduction, frequently involving heat recovery via steam generation.
Treatment of the cooled gas to remove air pollutants, and disposal of residuals from this treatment process.
Dispersion of the treated gas to the atmosphere through an induced-draft fan and stack.
There are many variations to the incineration process, but these unit operations are common to most facilities.
This chapter addresses the combustion and air-pollution control operations commonly used in municipal solid-waste, hazardous-waste, and medical-waste incineration facilities. The intent is to identify, and briefly discuss, the design features and operating parameters that have the greatest influence on emissions. Waste storage, feed preparation, and gas temperature reduction (which may involve heat-recovery operations) are addressed to a lesser extent.
This chapter also addresses the air pollutants emitted from incineration processes that are of primary concern from a health effects standpoint (see Chapter 5). Formation mechanisms and emission-reduction techniques are discussed. Information is provided on stack emission rates during normal operation vs. offnormal operating scenarios such as startup, shutdown, and process upset conditions. Fugitive emissions, residual ash, and scrubber water handling are briefly discussed
