AE Series Off Gas Preheating Continuous Feeding Equipment

AE series preheating continuous feeding equipment is the most advanced, clean, energy saving and environmental protection metallurgy off gas using equipment in nowadays. This is using the off gas from the electric furnace to preheat the raw materials, and avoided the high failure rate, complicated operation, can not charging materials continuously and other weakness from Shaft furnace preheating and preheating bucket and other traditional ways.  This system has been put into production in more than 20 factories in China and several other countries. And had gain marked affects in electricity saving, energy saving, production increasing, pollution reduction, and brought great economic benefits for customers. 

AE series preheating continuous feeding equipment has characteristics of continuous feeding, continuous melting, continuous smelting and others, which advantages are: smelting period is short, low power consumption, low noises, low investment cost and etc… 
Comparing with the traditional EAF, the technical index of continuously preheating and feeding EAF process are:

• Production capacity increases more than      10%.

• Smelting cycle is shortened by 10-15 Min.

• Save energy of 100-120kw.h/t for per ton      Steel.

• Electrode consumption decreases by      0.5-0.8%, Refractory material consumption reduces by 5%.

• 20-30% reduction of CO2 volume which is      released from per ton of Steel; Production site dustiness is less than      10mg/M3.

• Dioxin and CO emissions meets relative      emission standards, Flue gas and dust are decreased from 17kg/t to 11kg/t.

• Fully utilization of waste heat: On the      Conveyor section can preheat the materials up to 300 degree Celsius and      higher, and add burner in conveyor section that can raise the materials up      to 600 degree Celsius. The rear part of the waste heat can be used to      generate electricity or heating by steam which is produced by waste heat      boiler, the gas from the boiler basically can go into the bag type dust      collector directly.  But the traditional electric furnace system off      gas must go through the water cooled pipes, air forced cooler and other equipments,      it will consume much energy to cool the temperature down and then put the      gas into dust collector, so waste the energy from the off gas.

• De-duster Fan power reduces 30%.

• Noise is fewer than 90 decibels during the      electric furnace smelting cycle.

With fully considering of customers kinds of actual using status, AE series preheating continuous feeding equipment brings direct economic benefits to customers by lowest failure rate, highest energy saving index, biggest investment return.
