Mitigating Pyrophoric Deposits In Exhaust Piping During SIC CVI/CVD Processes By Introducing Water Vapor Into An Outlet Portion Of A Reaction Chamber

A method for manufacturing a ceramic matrix composite component, comprising:

• introducing a gaseous precursor into an inlet portion of a reaction chamber, the reaction chamber having an outlet portion that is downstream of the inlet portion;
• and
• delivering a mitigation agent into an exhaust conduit in fluid communication with and downstream of the outlet portion of the reaction chamber.

A method of mitigating harmful byproducts in exhaust piping during ceramic matrix composite manufacturing, comprising:

• delivering a mitigation agent into an exhaust conduit downstream of a furnace having a chamber comprising an inlet portion configured to receive a porous preform and an outlet portion configured to define a gas mixing space;
• and
• controlling the mitigation agent to control chemical reactions within the exhaust conduit.
