The characters of Burnray's gas-fired infrared pre-drying system (1) Compared to electrical heating system, adopting gas fuel can reduce energy cost significantly; (2) Higher combustion efficiency and larger radiation efficiency; (3) Wider regulation range of thermal load, high removal rate up to 30%, good preheating effect; (4) As metal fiber is of small thermal inertia, the surface temperature can drop down to room temperature in several seconds after work stopping,which makes it can effectively prevent fire accidents caused by power break; (5) With program controller, the control system has various functions: pressure regulation, pre-purge, automatic ignition, flame detection, pressure protection and stop alarming; (6) Independent control to each burner, makes you can start one or more as you need; (7) Long life time, up to several years.
