(1) the protective atmosphere heat treatment.
(2) uniform furnace temperature distribution and heating and cooling temperature of any given oven.
(3) materials separated and combustion gas water heating and ventilation rates, good for radiative heating of the occasion.
(4) for liquid heating as well as a salt bath furnace heat source.
(5) low running costs, high efficiency and low noise applications.
(6) heating thin components, requires burning a small number of occasions, for example, roller-type furnace, small pusher-type furnace
