Kirish. Siquv kompressor stansiyalarida detander-generator agregatlaridan foydalanish ularning iqtisodiy samaradorligini oshirishning istiqbolli yo‘nalishi hisoblanadi.
Maqolada bug‘ va gaz turbinali qurilmalarga ega issiqlik elektr markazlari va stansiyalariga yoqilg‘i gazini yetkazib berish siquv kompressor stansiyalarida qo‘llaniladigan detander-generator qurilmasi tarkibiga kiradigan turbodetander jihozining oqim qismini hisoblash ishlari bajarilgan.
Usul va materiallar. ANSYS CFX dasturiy ta’minoti vositasida turbodetanderlarning kurak moslamasini profillash, hisobiy-eksperimental tadqiqotlar o‘tkazish va olingan natijalarni tahlil qilish amalga oshirildi.
Natijalar. Tadqiqot manbalarini tahlil qilish asosida detander-generator qurilmasi yordamida yoqilg‘i gazini tayyorlashning texnologik sxemasi loyihalangan va agregatning asosiy qismlarini o‘z ichiga olgan qurilmaning uch o‘lchovli modeli ishlab chiqilgan.
Xulosa. Mualliflar tomonidan maksimal quvvati N = 498 kVt, gaz oqimi G = 3,32 kg/s, boshlang‘ich bosimi 5 MPa, oxorgi bosimi 1,5 MPa, gazodinamik podshipnikli bir pog‘onali detander-generator agregatidan foydalanish konsepsiyasi ishlab chiqilgan va amalda foydalanish taklif etilgan.
