Resumo

Biomass energy is the most abundant resource in the nature and it can be regenerated. Its sulphur content and ash content is lower, and its hydrogen content is higher than coal. It is one of the important energies which human depend on it to survive. Particle biomass fuel is a kind of solid fuel made by biomass material, with many advantages, such as high efficiency, clean molding, easy ignition, and low carbon dioxide emission, etc. It can replace other fossil fuels and can be used in the civil fields, such as cooking, heating, and other industrial fields, such as boiler burning and power generation. In this paper, the idea that particle biomass fuel is added into sintering production is presented. At the laboratory conditions, Φ 200 mm × 600 mm pot grate tests were carried out for three particle biomass fuel ratio (0%, 0.3%, 0.5%) respectively, vertical sintering speed were measured, they are 28.57 mm/min, 17.91 mm/min and 17.65 mm/min. Sinter metallurgical property were compared, reductive degree index are 65.72%, 81% and 83%, tumbler index are 70.13%, 51.03% and 50.87%, reduction degradation index (RDI + 6.3 mm) are 37.7%, 25.42% and 24.88%. The results show that it is difficult to use native biomass fuel in sintering process, Because it is easier to absorb more water, this leads to water content in the mix material higher than raw material, bed permeability is decreased, sintering speed is lower, the strength of sinter is decreased, but reduction degree index is higher. In the future biomass fuel carbonized will be further studied in sintering process.
