1kg gas LPG bằng bao nhiêu kg dầu DO,FO, Than củi, Kwh? Bằng bao nhiêu m2 CNG? và các nhiên liệu khác

Posted on Tài liệu kỹ thuật LPG, Tin tức 5486 lượt xem

Trong sản xuất công nghiệp hiện nay đang sử dụng rất nhiều nhiên liệu: Khí dầu mỏ hoá lỏng LPG, dầu DO, FO, Khí tự nhiên nén CNG, Khí tự nhiên hoá lỏng LNG. Điện.>> Do đó khi chuyển đổi sang nhiên liệu khác sẽ phát sinh vấn đề quy đổi qua lại giữa các nhiên liệu để tính toán khối lượng, công suất thiết bị cho phù hợp. Dưới đây là bảng quy đổi các nhiên liệu phổ biến.
