YETEN HAS BEEN AWARDED BY THE CERTIFICATE OF SUCCESS OF 2005.
The Yeten Combustion and Energy Technologies has been awarded with the Certificate of Success by Hauck Manufacturing Co. in their Yearly Sales Meeting between 10-13 September 2005 in Grantville-USA . During this meeting, it has been done a presentation to guests about the projects of 2005 that has been applied by Yeten. At the beginning of this presentation, it has been given some information to guests about the location and the importance of our country.
Mr. Etchmaier-The Hauck's CEO and Mr.Michael Shay-Sales Manager have presented this award to Mr. Ibrahim Turan-Yeten Company Director. Yeten is being represented Hauck , that is one of the leader companies in burner manufacturing in the world for 120 years, in Türkiye since 2002.
-----------------------------------------------
COOPERATION WITH JASPER Gmbh
It has been signed a contraction with Jasper GMBH-Germany which is one of the leader regenerative and recuperative burner manufacturers in the world. The regenerative and recuperative combustion systems manufactured by Jasper depend on the principle of increasing of combustion air temperature by means of draft. Using this system, up to 60 % of fuel saving can be obtained. They are used in aliminium and steel industries.
-----------------------------------------------
THE GEMICILERGUVEN METAL HAS ALSO PREFERRED YETEN
Gemciler has been founded in 1948 in Kahramanmaras. They manufacture copper sheets, rolls and tapes. Gemciler which is one of the leaders in their branches has TS-554 certificate. The new manufacturing hot annealing furnace is being commissioned by Yeten. The aim is to increase the combustion air temperature up to 200 deg C. In the system, medium velocity Hauck SVG and flat flame WHG burners are used.
Honeywell HC900 is used for system control and Fischer differential pressure transmitters together with orifice plates are used for fuel air flow measurement. To control gas flow, moduline linear adjustment valves and to control air flow, Aris butterfly valves are used. In this project, the flow control technic are applied.
The target points of this projects are to have temperature uniformity, to minimize the oxidation layer on the copper caused by combustion and to save more fuel.
-----------------------------------------------
EREN METAL ALIMINIUM CASTING LINE HAS BEEN COMMISSIONED
Eren Endustri A.S. has been founded in Kayseri Free Zone. It is a branch of Has Celik which is one of the most important aliminium manufacturers in our country. It aims to export the biggest part of its production. Yeten has finished the projects of the total combustion systems of the aliminium melting furnace with 10 MW capacity and the aliminium hot holding furnace with 3.5 MW capacity and the commissionings . All the safety tests have been done.
Two pcs. Hauck RRG 2112 in aliminium melting furnace, 2 pcs. Hauck RRG 2106 Beta burners per each holding furnaces have been used. Also, Honeywell 2500 controller for temperature and inner pressure control, Siemens S7-200 PLC and the operator pannel for sequencing and alarm system have been used.
The combustion air has been heated by a recuperator in aliminium melting furnace. The fuel air ratio has been controlled by a Hauck RRG pilot regulator fitted on the orificemeter on the cold line. This regulator triggers pneumatically the equal pressure regulators at the inlet of burners.
In hot holdings, this ratio has been supplied by impulse lines coming from the exit of air control servos at the inlet of each burners which trigger equal pressure regulators.

GIZEM FRIT MODERNISATION PROJECT IS CONTINUING
The GIZEM FIRIT has been established in 1979 in Adapazari. It produces firit for the white utensil manufacturers and emaye kaplama manufacturers inland and abroad. The firit production has been made by melting the mixture of bor and some chemicals in high temperature kilns.
First of all, the project has began with the modernisation of the existing system. The Hauck 2106 beta gas burner instead of the existing burners, Honeywell UMC 800 Controller to command and control the system and Fischer differential pressure transmitters together with orificemeters for fuel air measurement have been used. For gas flow measurement, moduline linear adjustment valve and for air flow measurement, ARIS butterfly valves have been used.
The cross limiting technic has been applied together with flow control by a developed software. As a result of this, the gas flow does not increase unless air flow increase and the air flow does not decrease, unless the gas flow decrease. Beside this, the combustion air temperature has been increased up to 200 deg C. According to this temperature, the air flow has been compensated. After this modernisation, 20 % fuel saving, decrease in melting loss because of low combustion air pressure, sensitive temperature and fuel air ratio have been obtained. Because of the decrease in man inisiative, a stable production quality can be supplied. The modernisations of first four kilns have been completed and the modernisations of the rest kilns goes on nowadays.

EKINCILER DEMIR CELIK(EKDEMIR) ROLLING FURNACE NATURAL GAS RECHANGE WORK HAS BEEN GIVEN TO YETEN
Ekinciler Iron and Steel Inc. (EKDEMIR) has been established in Iskenderun in 1983. The Ekdemir which tied to Ekinciler Holding is a very huge and integrated factory that has the latest technologies and a big export capacity.
The offer prepared by YETEN and HAUCK together for the rolling furnace with 100 ton/hr capacity natural gas rechange work has been accepted by EKINCILER Iron Steel .
The total energy requirement is 40 MW and the kiln combustion system is consist of 3 zones and 20 burners. In this project, 4 pcs Hauck BBG 2112, 8 pcs BBG 2110 and 8 pcs BBG 2108 series beta burners have been used. The combustion air temperature can be increased up to 450 deg C. In the control system, Honeywell HC900 hybrid controller has been used. Supplying all the gas way equipments, projecting the system, following the montage period and commisiong are being done by YETEN. The cross limiting technic has been applied together with flow control by a developed software. As a result of this, the gas flow does not increase unless air flow increase and the air flow does not decrease, unless the gas flow decrease.
-------------------------------------------------------------------------
THE TURKKABLO NATURAL GAS RECHANGE HAS BEEN COMPLETED
Turkkablo has been established in Izmit-Derince in 1963. It is the first company in Turkiye which produced steel based and whool aliminium conducturs and has TSE ISO 9001, BVQI ISO 9001 and ISO 14001 certificates.
The natural gas change works which is started in 2003 has been completed with changing the heat threatment and the billet annealing furnaces to natural gas in 2005. Six pcs. Hauck BOA series torchs with automatic ignition-open channel burner- has been used in open channels. The gas way armatuors and control pannels has been renewed in billet, heat threatment and annealing furnaces. In billet annealing furnace, Honeywell UMC 800 controller has been used. Beside very accurate temperature control, the process information can be saved in the device memory and followed in the display as curves. |
