Annotatsiya. Kirish. Maqolada parabolik quyosh konsentratorli geliopiroliz qurilmasidaa kungaboqar o‘simligi chiqindilarini pirolizi jarayonini issiqlik-texnologik rejimi tadqiqoti natijalari keltirilgan. Geliopiroliz jarayonini tadqiqot qilish uchun tajriba parabolik quyosh kotsentratorli geliopiroliz qurilmasi yaratilgan. Kungaboqar o‘simligi chiqindisini termik qayta ishlash jarayonida chiquvchi mahsulotlarni haroratga bog‘liqligi va material balansi tajribalarda o‘rganilgan. Qurilmada o‘tkazilgan tajribalarda geliopiroliz reaktoriga yuklangan 1 kg kungaboqar o‘simligi chiqindisi pirolizi natijasida 63 % bioko‘mir, 10 % suyuq va 27 % gazsimon yoqilg‘ilar olishga erishilgan.

Usul va materiallar. Parabolik quyosh konsentratorli geliopiroliz qurilmasi reaktoriga yuklangan biomassadan ajralib chiqqan bioyoqilg‘ilarning material balansi laboratoriya sharoitida boshlang‘ich namligi 10 % va o‘lchami 6÷8 mm bo‘lgan holatda amalga oshirildi. Tadqiqotlar kungaboqar o‘simligi chiqindisida amalga oshirilgan.

Natijalar. Olib borilgan tajribalarga ko‘ra piroliz mahsulotlarining umumiy chiqish miqdori 350-400 ^oC harorat intervalida o‘zgarishiga kam bog‘liq bo‘lishi aniqlandi. Shunday qilib, tajribada yuklangan 1 kg kungaboqar o‘simligi chiqindisi pirolizi natijasida 63 % bioko‘mir, 10 % suyuq va 27 % gazsimon yoqilg‘ilar olishga erishildi.

Xulosa. Ishlab chiqilgan parabolik kuyosh konsentratorli geliopiroliz qurilmasi kunduzgi rejimda siklni amalga oshirish uchun xususiy ehtiyojiga sarflanadigan energiyani quyosh issiqligidan qoplash imkonini beradi. Parabolik quyosh konsentratorili geliopiroliz qurilmasida olib borilgan eksperimental tadqiqotlar natijasida kungaboqar o‘simligi chiqindisi pirolizidan qattiq, suyuq va gazsimon yoqilg‘i namunalari olish mumkinligi aniqlandi.
