HOT RECYCLING PLANT (HRC Series)



Hot Recycling Plant

Understanding today's pressing environmental issues and rapidly increasing pollution problem, as a member of the world population, LINNHOFF is committedto protect and conserve our last natural resources !e strive to balance between development and environmental protection by being innovative in the designof our system

!ith good e"periences gained from #ermany, we learned that a total system must be able to combine Pollutants Reduction Energy Conser!ation

Te"#erature Control and "aterial treat"ent$ ultimately achieving the highest level of waste recycling but not compromising the mi" $uality

Ad!antages%

&' Pollutants Reduction

%roper control of the temperature and recirculation of hot air minimi&es the production of harmful fumes from the heating of asphalt

he ma(ority of the harmful substances recirculated are being e"pended at the hot air generator's flame &one, thus giving us a cleaner e"haust )sphalt fumesnot circulated are being captured by fines in(ected at the Fumes )rrester before going into the baghouse

' Te"#erature Control

Full automatic control by the computer on the air flow through the control of the dampers and the temperature monitoring by the thermometer at various

positions, bringing the *)% to the ideal temperature at reduced o"idation for the mi"ing with the virgin material



' Energy Conser!ation

he burner uses high pressure to atomi&e the fuel out of the no&&le )ll the air re$uired for the combustion is supplied by an incorporated radial+a"ial flow fancoupled with a regulator plate regulating the fuel feed valve to ensure e"act air oil proportioning, thus ensuring fully combusted flame to be developed in theburner head -inimi&ed fuel wastage gives the owner a significant saving over oneyear operation

he flame entering the hot air generator is further mi"ed with the returned air to give the air a final temperature of appro"imately .//01 for optimum heattransfer to the *)% he special construction of the system ensures the optimum temperature of 23/24/01 for the *)% before discharging into a buffer silo5y this method of recirculating the hot air, appro"imately 647 of energy is saved

*' +aterial Treat"ent

In the treatment of *)%, it is always important to prevent e"cessive fines or asphalt dust being produced, reasons being8

• the heated asphalt dust will be cho9ed up the pollution control system by stic9ing onto the filter soc9s

• the plant circulation system and drum may be progressively coated with the asphalt thus re$uires constant cleaning

• possible change in the properties of the *)%, eg o"idation and burning due to increased surface area where too much hot air is in contact with the

asphalt



LINNHOFF is able to offer the -ILL 1*U:H;* as a total solution which is proven for more than ten years in #ermany

Control Syste"

1lear flow charts and logical arrangements of function 9eys and control monitor guarantee ease of operation and perfect handling of all automatic controlsystem

%lant operator can simultaneously control various functions, thus reducing the number of people re$uired to run the complete plant

!ith the high speed computer controlling the plant in the bac9ground, essential communication with the operator is done through a mimic diagram displayedon a touch screen monitor he system is highly user friendly with control command to the computer being input via the computer screen by the touch of afinger
