NOVELTY - Preparation of refined gasification waste fuel involves taking stems and leaves of sugarcane, corn stalk leaves, sorghum stem leaves, reeds leaves, cassava stem, other weeds, and leaf litters; mixing and crushing them to obtain main material; mixing combustible garbage, waste plastics, deodorizer, oxidant, coagulant, and fragrance; grinding them to obtain secondary component; mixing main material and secondary component at weight ratio of (6-8):(4-6); press molding into different shape mold blocks suitable for different types of gasification furnaces; and packaging.    USE - Preparation of refined gasification waste fuel.    ADVANTAGE - The refined gasification waste fuel can be fully gasified and combusted to produce residual ash product of less than 0.20 kg, without producing bad smell and harmful gas discharge to environment, thus achieving sanitation, safety, practicality, efficient energy-saving, and environment protection.    DETAILED DESCRIPTION - Preparation of refined gasification waste fuel comprises setting large plant stems and leaves into large-scale plant equipment; weighing and crushing them; mixing; pressing; and molding. It preferably involves taking stems and leaves of sugarcane, corn stalk leaves, sorghum stem leaves, reeds leaves, cassava stem, other weeds, and leaf litters; mixing and crushing them to obtain main material; mixing combustible garbage, waste plastics, deodorizer, oxidant, coagulant, and fragrance at weight ratio of (2-4):(1-3):(1-3):1:(0.2-0.4):(0.1-0.3); grinding them to obtain secondary component; taking main material and secondary component at weight ratio of (6-8):(4-6); mixing them; press molding into different shape mold blocks suitable for different types of gasification furnaces; and packaging using special packaging bag for block gasification fuel to obtain finished product. The gasification fuel together with external packaging bag is used into each gasification furnace, and is used according to operation method of gasification furnace, which involves ignition heating.
