Dryed aggregates furnace
Dryed aggregates furnace is suitable for secondary vulcanization silicone rubber, Polyurethane silica gel mould sulfurization, food industries silicone molding vulcanized, medical silica gel sulfide, silicone molding vulcanized, silicone casing vulcanizing, baking, drying, daub to finalize the design.
DYG series silicone rubber industry special secondary vulcanization oven adopts national science and technology commission key promotion of far infrared heating new technology, infrared components are heated after 2 - more than 15 micron far infrared ray radiation, when it is absorbed by the heated objects can be converted into heat energy, thereby gaining rapid drying effect, to shorten the production cycle, save energy, improve product quality, etc. Temperature control meter uses the import component, fashionable, easy to use, save energy!
We can design and manufacture many kinds of model ovens according to customers detailed requirements.
Please kindly contact us and tell exact sizes of working room (DXWXH).
Thanks for your attention! looking forward to cooperating with you in the near future.
1) Generating hot air for drying and heating process;
2) Hot air temperature: 80-800 degree C (adjustable)
3) Heat output: 600,000-12,000,000 kcal/hour;
4) Temperature control accuracy: +/- 15 degree C
5) Clean hot air is available by using tubular heat exchanger
GL series reciprocating grate hot air furnace is specially designed for burning biomass fuels which are usually featured by low heat value, high moisture content and quite different fuel size. It is mainly consisted by reciprocating grate, mechanical drive system, combustion chamber, feeding hopper, ash remover, blower and exhaust fan.
The air-cooled reciprocating grate is inclined stair-like grate of which each stair is removable. When biomass fuel is fed onto the top stair via the feeding hopper, it pushes the fuel down the length of the grate through distict drying,gasification, combustion and burn-out zones. The combustion air is blown into the combustion chamber from the grate bottom through the holes in each grate bar. The ash is automatically discharged off at the end of grate into an ash conveying system. After heated, the hot air (800-1000 ℃) will be discharged by the exhaust fan for drying or heating process. Tubular type heat exchanger can be installed after the furnace to get clean hot air.
1) Flexibility for various kinds of fuels: Reciprocating grate can perfectly burn various kinds of fuels, such as coal, wood chips, bark, sawdust, forest waste, agriculture waste, rice husk etc. with low heat value and high ash content.
2) Suitable for fuels with high moisture content: The grate can be divided into Four zones:
a. Drying zone: for preheating and dispersing the fuel
b. Gasification zone : gasifying fuel surface for easy burning
C. Combustion zone: fuels completely combusted
c. Burn-out zone: ash discharging and collecting
3) Perfect and complete combustion: the reciprocation movement can perfectly disperse and turn over the fuels during combustion, so the combustion is perfect and complete.
4) Good insulation and high heat efficiency: the heat insulation layer is 750 mm which can make sure the surface temperature of furnace is about 40 °C. Less heat loss and complete combustion can guarantee the heat efficiency reach 90%.
5) Long life-span: the combustion chamber frame is made by high strength steel and lined by casting heat resistant cement and firebricks. The grate bar is made by heat resistant alloy steel. The normal life-span can reach 10 years.
6) Automatic operation: fuel feeding, ash discharging and grate moving are fully automatic.
7) Stable output temperature: Temperature control is achieved by accurately regulating the combustion air, grate movement and feeding speed. All the fans are equipped with inverters. Grate drive motors are stepless speed regulating type.
8) Safety measures: exhaust fan is equipped to create negative pressure burning condition. Ash removing port is water sealed. The negative pressure and sealed burning chamber can make sure operation safety as well as cooling the grate.
