1. Combustibility behavior of PCI coals, green petroleum coke and charcoal fines used as fuel for injection into blast furnace tuyeres
Abstract Pulverized coal injection (PCI) into blast furnace tuyeres is widely used by integrated steel mills worldwide to reduce the consumption of coke and costs. High injection rates are desirable. The big challenge is to achieve them with cheaper and lower quality raw materials, without losing the quality of the hot metal and the productivity of the blast

2. Combustibility and reactivity of coal blends and charcoal fines aiming use in ironmaking
Charcoal is a very important reducing agent in Brazil, the world’s largest steel industry based on charcoal blast furnace. Charcoal generates large amounts of charcoal fines during its production and processing. A good alternative for harnessing this fuel is the injection into coke-based blast furnaces via PCI process (Pulverized Coal Injection), a key tec

3. Gestão da qualidade aplicada à melhoria do processo de produção de carvão vegetal / Quality management applied to improve the production process of charcoal
The forestry sector contributes significantly to the Brazilian Gross Domestic Product (GDP), as well as to generate employment and income. The research for this sector brought numerous technological advances in areas such as forestry, plant breeding, soil management and water resources. However, few studies have studied management, responsible for increasing

4. Desenvolvimento de briquetes autorredutores a partir de carepas de processamento siderúrgico para utilização em forno elétrico a arco
A indústria siderúrgica do Estado do Rio Grande do Sul é do tipo semi-integrada e produz aço a partir de sucata, utilizando fornos a arco elétrico. Em suas atividades gera vários tipos de resíduos, dentre estes as carepas, cujo componente principal são óxidos de ferro. Este material não encontra utilização e geralmente tem destinação final em a

5. Efeito da granulometria e de aglutinantes nas propriedades de briquetes de finos de carvão vegetal / Effect of size and binders in briquettes properties of charcoal fines
O objetivo deste trabalho foi avaliar as propriedades dos briquetes produzidos com finos de carvão vegetal para a geração de energia. Para confeccioná-los, foram utilizados três frações de finos de carvão (20, 35 e 60 mesh) e aglutinantes de amido pré-gelatinizado (APG), farinha de babaçu, dextrina, silicato de sódio, nas proporções de 15, 25 e

6. Caracterização de carvão vegetal para a sua injeção em altos-fornos a carvão vegetal de pequeno porte
Hot metal in small blast furnaces (working volume <300 m3) in Brazil represents ca. of 35 % of all of hot metal produced in the country, generating a waste, the charcoal fines. This Project studies the use of this waste into Powder Coal Injection Installations. The main point studied is the behavior of charcoal to be injected into the tuyeres of blast furnac

7. Redução do teor de cinzas dos finos de carvão vegetal por concentração gravítica a seco
The ashes, or more especifically the impurities, of charcoal are harmful to the production of pig iron, causing higher charcoal consumption, larger slag volume and increased costs. The elimination or minimization of the ashes content is imperative. The reduction of impurities was performed based on the differential properties identified from the technologica

8. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom
