Application scope：
This furnace is supported for each kind of material drying
equipment as a kind of general hot air unit , which is widely used
for dehumidification of cereal ,seed ,feed and fruit ,heating and
wet extraction of vegetables ,mushroom ,Jew's-ear ,tea ,tobacco ,
food ,pharmaceutical products ,chemical raw materials and light and
weight industrial products ,as well as for heating of various
facilities and dehumidification of warehouses .
Working principle：
Combining burning and heat exchange as a whole ,this furnace adopts
the novel indirect heating technology of performing heat exchange
at high temperature position of the furnace ,inside which, smoke
and sir flow separately ,heating has no contamination ,thermal
efficient reaches (60-75%)therefore ,it features speedy temperature
rise ,compact dimension ,convenient installation ,reliable
operation and lower cost (only half of that by boiler heating
system ).High temperature resistant measure is taken to extend its
service life significantly in comparing with the tube still hot air
furnace ,whereas ,cross brushing of heat sink by the smoke and
negative pressure smoke exhaust are used to ensure a clean heat
exchanging position with stable thermal performance .Fueled by any
coal or firewood ,it is equipped with two phase air inlet unit
,which ensures sufficient combustion ,each technical and economical
index of the furnace has reached the domestic leading level .
