The conventional top-fired hot air furnace systems adopt a horizontal form of ar-rangement of hot air stubs,and the hot air main pipe is connected to the enclosure pipe by a vertical pipe.The L-shaped hot air branch technology eliminates the vertical pipe,reduces the height of the hot air main pipe to the same elevation as the enclosure pipe,shortens the total length of the hot air pipe,so as to improve the stability.This L-shaped hot-air branch pipe has a compensator in the ver-tical section to absorb the expansion deformation of the hot-air branch pipe and the hot-air furnace body during the baking period.In addition,a hot-air valve and an axial compensator are installed in the horizontal section of the L-shaped hot-air branch pipe for hot-air valve maintenance.This tech-nology can also be used in the renovation of internal combustion and external combustion hot air stoves to reduce the investment in the project.
