MEASURING FOR A PLUME MANAGEMENT SYSTEM
1. Measure the plume management flue (M) from the
centre of terminal, along the required route to the
centre of the plume outlet.
Fig. 34 Plume management length M
ADDITIONAL BENDS:
2. Adding bends to the plume management system
reduces the actual plume management length. Each
bend has an equivalent straight length and must be
factored into the overall effective length.
–
90° bend is equivalent to 1500mm.
–
45° bend is equivalent to 750mm
Fig. 35 Plume management bends
EXAMPLE:
Using two 45° bends will reduce the permissible length
by 1500mm.
A Greenstar 28i junior has a maximum permissible plume
management length of 4500mm, so using two 45° bends
will reduce the straight length to 3000mm.
All boilers have a maximum permissible
plume management length, refer to
figure 33.
