EFFI CIENT UTILIZATIONS OF NATURAL GAS iN THE INDUSTRY Lionel GAURIER Together wilh his activitıes asa Technical Counsellor, llonel GAURIER spends an lmpodant share ot his time with lnternatlonal relations: trainlng in gastechnology in Shanghai University, or in Guayaquıl or Bogoto; technical advices in South Korea, Russla or Kazakhstan: confer• ences in many lnternational gas congresses, in seme cases as ropean expert, as in Brou nEeu l Darussalam. SANA0DEDOĞAL GAZIN GELİŞMİŞ KULLANIM BİÇİMLERİ ÖZET:Çok uzun geçmişi "Gaz de France" 'a gazın işlerliği otan çeşitti alanlarda, öıellikle de gazın kullanılma atonında, değeri/ birdeneyimibiriktirme olanağını sağlamıştır. 1950 tiyıllarda doğal gazın geliş/bu deneyimi daha da pekiştirmiştir: Mevcutdonatımın bu yeni enerji kaynağına uydurulması, yeni teknolojilerin ortaya çıkarılması bize, bl/gl/erimizl gellştirme fırsatını doğurmuştur. Bu gün için Gaz de Fronce'ın "Sofregaz" gibi yan kuru/uştorının amacı, Fransa'nın enerji tüketiminde doğal gazın payını arttırıcı yeni araçları gelişflrmek, bunu yaparken de enerji tasarrufunu sağ/omaya çatışmaktır. Çevre koruma ve güvenlikle llg/11 yeni kavramların gün ışığına çıkışı bu eğitimi güçlendirmektedir. Bu metin, sanayi alanındaki son yenilikler hakkında bazı örnekler sunmaktadır. ABSTRACT:From years of gas utillzations. fhe french gas industry stored a valuable experience ln applications using thls energy. Thls experlence has been strengthened when natural gas was discov ered: retrofit existing equipments, develop new uses, offered an opportunity improve our knowl edge. Now, the main target of Gaz de France research activities is to develop new means to help maintain or increase the share of gas in the national energy consumption, whlle lmproving the energy smaevninfagls . pThroet ecmtloerng eancde wofi tnhe ew necorgnecteicpatsl , preoltaetnetd to the environial hazards, wlll enhance the trend. This paper presents sample examples of the ıast developments in the industry. 1. GENERAL CONSIDERATIONS Improving ehe effıciency, procecc ebe environmenc are ehe moros of ebe fall of cbis cencury. Nacural gas is a reacly answer ro cbese scbemes. Ic is ebe less pollucing fossil fuel: for a given power oucpuc, İt procluces no clusc, less C0 1 , ancl less Nü, cban ocher fuels. Decencralize ehe energy procluccion has been a way ro improve ehe energy efficiency.

Ic is now on ebe cimecable wben we scudy cogeneracion (alchougb it is not yer developped, due ro ebe success of ebe french nuclear program. Among ehe numerous applicacions ebat bave been developped during ehe lasc years, from burners co equipmencs, we bigblighc some efficienc uses ofnatura!gas in differenc fields of induscry. 2.INDUSTRIAL BURNERS 2-1. The "Opposite Swids Burner". Among ebe burners ebat were designed lacely, ehe opposice Swirls Burner, developped for a specific purpose, bas been used in many applicacions. Presenced in figure 1 cbis burner is supplied wich gas chrougb radial holes, drilled ar ebe back end ofehe cbamber. Air is injecced cbrough cangencial boles ser in cwo rows, inducing rocacions in opposice direccions, cbus creacing opposice swirls inducing an imporcanc turbulence. Due co cbis cechnology, cbere is a fasc mixcure becween gas and air and ebe flame is cbus shorc and very sceacly. Ics greac qualicies make chis burner very incerescing in many fields of ehe induscry. le has a large versacilicy eicher in power (it operaces becween 5 % and 200 % of irs nominal power Gas Air One Row of 12 Gas lnjectors
