Workability
Workability is
comparatively good;
however, since the
environment
surrounding the burners
in the lower zone is at
a higher temperature,
the workability is not
good
Working environment is
good
Workability is slightly
inferior, since the
environment
surrounding the roof
burners is relatively at
a higher temperature
and there are many
burners used
