1. Potencialidade de uso não potável de água de lagoa de detenção
RESUMO As águas de lagoas de detenção geralmente não são utilizadas produtivamente e o seu potencial é desperdiçado. Por estarem disseminadas nas cidades, a utilização dessas águas pode reduzir os custos com transporte de água, além de permitir a preservação de águas de melhor qualidade para fins mais nobres. Algumas das possíveis utilizaçõ

2. Evaluation of mortar properties obtained through partial substitution of Portland cement by ashes of oil palm empty fruit bunch
Resumo Atualmente, o óleo de palma é líder em produção e consumo dentre os óleos comestíveis comercializados, com uma produção mundial que ultrapassa 66 milhões de toneladas anuais. Estima-se que a produção de resíduo da queima do engaço do dendê como combustível nas caldeiras corresponde a 5% em massa do total de óleo extraído. Este trabal

3. Antioxidant effect of the guava byproduct in the diet of broilers in the starter phase
ABSTRACT This work aimed to investigate the antioxidant capacity of the guava agroindustrial waste as a functional additive in broiler feed to improve the performance and meat quality of boilers. The experiment was conducted in a completely randomized design, consisting of four treatments and six replicates with 12 birds. Treatments included different levels

4. Effect of partial replacement with thermally processed sugar cane bagasse on the properties of mortars
ABSTRACT Sugar cane bagasse is a residue of the sugar-alcohol industry, and its main destination is represented by burning boilers for power generation. The bagasse cogeneration of power produces a sugar cane bagasse ash (SCBA) residue that does not have a useful destination. Ashes are commonly studied as pozzolan in Portland cement production. International

5. Evaluation of Corrosion Caused by the use of In Natura Biogas in Steam Generator Boilers of Carbon Steel Structural Elements
This work evaluates the corrosion process caused by the presence of hydrogen sulfide in the biogas in natura, in steels commonly used in the construction of steam generator boilers, simulating conditions close to those found on the real application of these materials, exposing the test bodies directly to biogas in natura, flame of combustion and gases result

6. INFLUENCE OF THE MODEL SCALE ON HYDRODYNAMIC SCALING IN CFB BOILERS
Abstract The paper presents the results of experimental verification of the simplified set of scaling parameters for which the particle density as well as the cold model length scale may be chosen independently. The tests were carried out on two large scale 1/10 and 1/20 geometrically similar cold models of the Lagisza 966 MWth supercritical CFB boiler. The

7. TRATAMENTO DA VINHAÇA POR ADSORÇÃO EM CARVÃO DE BAGAÇO DE CANA-DE-AÇÚCAR
The aim of this study was to develop an effective and economically viable technology for the treatment of vinasse, prior to its disposal in the soil for fertirrigation, aiming this way at reducing the environmental impacts generated by inadequately discarding this effluent. The primary treatment of vinasse by adsorption was evaluated. Adsorbents were prepare

8. Estudo da degradação energética em tubulações industriais
At REGAP, boiler feed water with high pressure is delivered from pumps 121-P- 01A/B/C/D, located at Utilities Unit, for various utilities clients within the refinery: boilers F-121-01A/B/ C, boilers 103-E-01, the steam generator 209-V-03 and furnace 52-F-01A/B. These customers are spread over a vast area and have a range of demands of pressure. To be able to

9. Análise termodinâmica de ciclo combinado operando fora das condições de projeto / Thermodynamic evaluation of a combined cycle operating under off-design conditions
O atendimento da demanda crescente de eletricidade, associado à necessidade do cumprimento de metas de emissões de gases causadores do aquecimento global, será um grande desafio ao setor elétrico nas próximas décadas. A geração de eletricidade ainda necessitará de combustíveis fosseis por muitos anos e a busca por eficiência energética nos proces

10. Utilização da cinza do bagaço da cana-de-açúcar como agregado miúdo em concretos para artefatos de infraestrutura urbana
Brazil is the main sugarcane world-producer and it is the leader in all segments (sugarcane, sugar and alcohol). The waste consisting of sugarcane bagasse is produced at the end of grinding process and it is used to generate energy through burning in boilers. At the end of burning, the ashes of bagasse are often thrown into environment improperly. In this co

12. Corrosion behavior of mild steel and SS 304L in presence of dissolved nickel under aerated and deaerated conditions
In dual purpose water/power co-generation plants, the presence of high concentration of Cu and Ni in the re-circulating brine/condensate as a result of condenser tubes corrosion has been attributed as one of the several causes of corrosion damage of flash chamber materials and water touched parts of the boilers. The present investigation deals with the effec
