The pulp and paper industry use biomass residues, such as sludge bark fuel to provide energy for their plants. However, issues high-water content or low heating value limit the amount of that can be utilized. Processes improve heat generation include densification, which facilitates transportation handling increase yield. technical feasibility briquetting is a function feedstock preprocessing. This study introduces novel approach briquette production from residues by utilizing wet with water...

Biomass is nowadays a very important alternative to energy consumption, since it provides less environmental harms. Briquettes come as an option they include logistical and efficiency advantages. This study aimed characterize Leucaena leucocephala (leucena) Gonoacantha piptadenia (pau-jacaré) biomass, define their potential verify the briquettes' moisture content mechanical resistance. Six treatments were provided: 2 species three different contents (10%, 12% 15%). Fifteen briquettes...

According to the environmental and energy global scenario, biomass emerges as a promising source of for its availability, low emissions greenhouse gases it is renewable source.However, disadvantages in use problems with transportation, handling, storage calorific values impair purposes.Therefore, improve use, compression becomes an efficient alternative.Briquetting process that changes material having regular shape, increase density higher value per volume.However, heterogeneous material,...

With the increasing demand of resources for production sustainable energy, use solid biofuels becomes an important alternative since biomass is a clean and renewable source energy.The aim this study was to compare characteristics different types briquettes.The raw materials used were residue sugarcane, pine sawdust red angelim.All with moisture content 10% particle size (granulometry) retained in sieves 20 35 mesh.The results show that angelim briquettes had greatest mechanical resistance...

The use of biomass as raw material in renewable energy production has been studied alternative source to fossil fuels.The aim the current study is physicochemical characterization Leucaena leucocephala (leucaena) tree species order produce briquettes.Leucaena wood treated with three moisture levels -T1 (10%), T2 (12%) and T3 (15%)was used briquettes.The was divided following stages: analyzing grinding lignin cellulose particle size distribution, chemical analysis, calorific value...

In lignocellulosic biomass, the volatile matter can vary from 65 to 85%. Different standards are described in literature for obtaining this parameter. However, it is observed that some studies of regression models have not considered these differences. They create a content database, where same parameter different. Thus, objective study was verify whether different present statistically equal values. That if they be compared with each other, without danger bias. For this, three types...

Ashes constitute a waste produced in the heat generation process from bioenergy. This study aimed to improve biomass energy efficiency used an industrial boiler. The physicochemical analysis was perform improvement quality of for solid fuel. Four types (eucalyptus bark, wood chips, sawdust, and recycled waste) were analyzed. material (ash) collected every two months over one year. All samples characterized regarding proximate analysis, chemical composition (macro micronutrients),...

Brazil emerges as the world's second-largest producer of broiler chicken.In production, there is formation poultry litter, usually consisting sawdust, water, feed, droppings and feather chickens.After chicken lots are created, material discarded.The aim this study was to characterize biomass from litter analyze its potential a raw for biochar.The samples were collected in three different times: Pinus spp.sawdust, with creation one lot two lots.Moisture tests proximate analyzes performed...

The use of Chromated Copper Borate (CCB) for wood treatment is known with several studies on a laboratory scale. However, there lack field to analyze the effect CCB over time. This study aimed evaluate properties Eucalyptus urophylla S.T. Blake x grandis W. Mill ex Maiden (called E. urograndis), treated as well leaching chromium, copper and bore (Cr/Cu/B) in test. experiment, untreated (no application), was installed 2016 remained until 2018. Wood physico-mechanical were evaluated each...
