: when do we use natural draft,forced draft,induced draft and balanced drafts.
: Please list out some criteria to determine how the choice of draft is made??
Natural Draft would be used when it is impossible to use anyother type of draft the other ones well you could use forced draft if only you have an electric blower that is used only for light off or if you can turn over you forced blowers enough to get the correct air pressure for light off draft. i have never used the other 2 ones personnaly but if you give me a few days i have some books i can look in and they are fabulous for these questions.
