Working pressure is between 100 and 125 psi (6.9 and 8.6 bar; 690 and 860 kPa). Where composite firing is used, [4] there are several possible arrangements for the heating gases. [6] Most use a double-pass tube arrangement where another dry back combustion chamber routes the gases from one tube bank to return through the other.
