“…A cyclonic combustor consists of a rotational flow inside a cylindrical chamber, where the particulate solid fuel in combustion follows a cyclonic motion caused by the tangential air injection from outside of the environment to inside of the combustor through a fan. ZARZYCKI et al [24] and CAR-NEIRO et al [25] describe the structure of this technology studied with more details. The main difference between the boiler used in this work and the commercial one, is the "water wall".…”

“…It means that the fuel burn while performing tangential movement in relation to the combustor axis-line, exchanging the heat with water flowing outside the reactor wall. This technology enables a stable flame along the combustion zone with a more efficient mixing of the fuel with the oxidant, reaching high values of combustion efficiency around 98.4% to 99.6% [25].…”

“…Hence, the electric generator efficiency is adopted between 16 and 42%, taking into account the estimated values presented in Figure 6 to calculate the electric and mechanical powers of the steam turbine. As previously stated, the steam turbine operates with a cyclonic combustion boiler of 44% thermal efficiency [25], allowing it to operate at low pressures.…”

In the Amazon, local electrical energy production is very important due to the large number of isolated communities, usually far from the conventional grid. In this context, steam turbines are relevant technologies to be used in the region, since waste biomass is widely available in several communities, besides, where sustainable agricultural activities take place, such as the use of açaí seeds, sugarcane bagasse, among others. Currently, there are not many relevant studies in the literature for small steam turbines operating at low pressure, conditioned to the reality of the Amazon region. Hence, the main goal of this work is to develop an experimental study of a small steam turbine operating at low pressure, in order to apply it to small energy demand, typically found in the Amazon. We developed measurements on the behavior of mechanical and electrical powers in relation to the shaft rotational speed of the small steam turbine, taking into account pressures of 0.1, 0.2 and 0.3 MPa. We concluded that the preliminary experimental survey, made in this work, demonstrates a good mechanical behavior of the small turbine and could be an alternative for electricity generation system to supply small demands in isolated communities in the Amazon, taking advantage of biomass from sustainable agricultural activities.

ABSTRACT. Various kinds of biomass fuels are used for boiler and other kinds of thermal applications. The presence of moisture, ash and calorific value are known to be the most significant quality factors which influence the effective performance of a biomass fuel for a plant. The reasons for measuring the above mentioned quality factors are to perform the economic analysis and to control the combustion. The relevant industries are interested to obtain a method for predicting these quality factors quickly and consistently; and also to identify biomass fuels containing optimal level of these factors. In the present work, five different biomass fuels have been considered such as rubber wood, eucalyptus wood, mixed wood (tamarind tree and neem tree woods), palm shell with fiber and juliflora woodchips. The moisture content in the considered woods have been found to be 27.74 wt.%, 37.78%, 30.19 wt.%, 23.26 wt.% and 37.01 wt.% respectively. The main objective of this work is to maximize the efficiency of production. Grey relational analysis has been carried out to optimize the moisture content, ash content and calorific value in order to achieve cost savings and fuel efficiency. Also, the economic analysis has been done with the operational costs. KEY WORDS: Biomass, Fuels, Energy, Boiler, Optimization Bull. Chem. Soc. Ethiop. 2023, 37(4), 1055-1064.
