wet sprinkler system in coal-fired baghouses

[pmover]

fellow engr's,

forgive me for the duplication of this question. i believe that perhaps this forum's audience may be able to provide additional valued feedback.

i recently encountered this matter and find it, let's just say pathetic thinking for now unless there are justifications for the design. i am posting this query on behalf of other individuals, but i now understand that another location is subject to the same situation, except that the other location is installing a dry-pipe system.

also, i trust this would be the proper forum to address this matter, even though it does address fire protection issues.

coal-fired boilers with baghouse modules...ID fan located downstream of baghouse modules.

the designer installed a wet-pipe sprinkler system and even had sprinkler heads installed inside the baghouse. it is my strong opinion that having sprinkler heads (wet ones at that!)inside the baghouse is potentially a serious problem to equipment and/or personnel. if the system ever activated while boiler is in operation, a potentially serious condition may exist.

is anyone familiar with other installations of similar designs? if so, what are the justifications, codes/stds, etc.?

any stds/codes that can be referenced to justify/not justify the installation of sprinkler heads inside baghouses?

my opinion, this matter needs attention before a bad situation gets worse.

thanks!
