3 -1. Definition & Mission
• The General Arrangement drawing is a basic document which shows
the arrangement of the Boiler, Steel Structure, Auxiliary equipments,
Air & Gas ducts and Major Piping etc. relative to each other in the
Proper area specified by Customer.
• The G/A drawing visualizes the actual size of the various equipments
and represents them in a scaled down manner in both elevation and
plan views.
G/A drawing is just for indicating the general information, but all the more information of actual
platform area, partial platform elevation and local stair/ladder location etc. refer to the relevant
steelwork drawings.
• The mission of G/A drawing
 To ensure optimum arrangement/position of the various equipments
within the available space. (Economical efficiency)
 To ensure easy access and maintenance.
 To co-ordinate between detailed design and Aux. equipments.

Air Duct System ;
Cold air supplied from FD fan is
after heated by hot gas in the
GAPH. and hot air is transported
through wind box into the burner.
for combustion.
Gas Duct System ;
After recovering heat from hot
flue gas at the furnace and
through to the SCR, GAPH,
