Chiqindilarni yoqish uchun o’tga chidamli materiallarni qanday tanlash mumkin?

Recently, many customers have inquired about refractory materials for waste incinerators. In view of the selection problems faced by customers, the editor has compiled a list of refractory materials for waste incinerators for reference only. Different types of incinerators have different selections according to their types, temperatures, and parts. Please refer to them carefully.

Umumiy kuydiruvchilarga partiyali, panjarali, CAO yoqish tizimlari, suyultirilgan yotoqli va aylanadigan o’choqli yondirgichlar kiradi. Chiqindilarni yoqish uchun o’tga chidamli materiallar quyidagi xususiyatlarga ega.

① Good volume stability; ② Good high temperature strength and wear resistance; ③ Good acid resistance; ④ Good seismic stability; ⑤ Good corrosion resistance (CO, Cl2, SO2, HCl, alkali metal vapor, etc.) ⑥Good workability (unshaped); ⑦Good heat and heat insulation.

Turli xil yoqish moslamalari, foydalanishning turli qismlari va har xil ish harorati, quyidagi tanlov takliflari faqat ma’lumot uchun:

Yonish kamerasining tomi, yon devorlari va burnerining ish harorati 1000-1400 is, yuqori alyuminiyli g’isht va 1750-1790 ℃ refrakterlikli loyli g’ishtdan, 1750-1790 ℃ refrakterli plastmassadan foydalanish mumkin. ham ishlatiladi. XNUMX

Panjara tomonining yuqori, o’rta va pastki qismlari 1000-1200 ° S haroratda ishlatiladi, silikon karbidli g’isht yoki refraktsionligi 1710-1750 ° S bo’lgan loy g’ishtdan, aşınmaya bardoshli quyma materiallardan ham foydalanish mumkin. foydalanish;

Ikkilamchi yonish kamerasining tomi va yon devorlarining xizmat qilish harorati 800-1000 is ni tashkil qiladi va 1750 ℃ ​​dan past refrakterlikli loyli g’isht yoki loydan yasalgan quyma materiallardan foydalanish mumkin;

Issiqlik almashinadigan kameraning yuqori va yon devorlari, purkagich kamerasining yuqori, yon devorlari va pastki qismi 600 ° C dan pastroq haroratda ishlatiladi. 1710 ° C dan pastroq refrakterlikka ega loyli g’isht yoki loydan yasalgan buyumlardan foydalanish mumkin;

Baca va tutun kanalining ishlatilish haroratini 600 ° C ga sozlang va 1670 ° C dan pastroq refrakterli loyli g’isht yoki loydan yasalgan buyumlarni tanlang.

Yuqoridagi kuydirgichlar uchun o’tga chidamli materiallarni tanlash muayyan shartlarga asoslanishi kerak. Har xil turdagi yoqish uskunalari turli xil omillar bilan birgalikda uskunaning ishlashi paytida eng talabchan sharoitlar bilan aniqlanishi kerak.
