Processing of pine wood chips in a pilot-scale downdraft gasifier generated a carbon-rich fly ash as a byproduct. Studies on biomass-derived fly ashes have generally focused on their direct characterisation, as generated, to develop options for utilisation or disposal. Analogous to studies on coal-derived fly ashes, strategies were applied here to assess the feasibility of isolating chars for v...

This paper reviews ways that biomass can be converted by thermal depolymerization to make synthetic gas, i.e. syngas. Biomass, being carbon neutral, is considered as a form of solar energy stored during the growing season by photosynthesis. An effective biomass is one with low moisture and ash content, high lignin content, high calorific value, and small particle size. Woody biomass with low as...

Direct firing of biomass in conventional clay brick manufacturing process aggravates deforestation, climatic change, poor economic benefits to rural industries, and health issues the public. To overcome such drawbacks, adaptation eco-friendly energy sources, implementation advanced technologies conversion systems systematic studies on are mainly focused recent times. The utilization biomasses t...

The development of a one-dimensional (1D) phenomenological model for biomass gasification in downdraft reactors is presented this study; the was developed with aim highlighting main advantages and limits related to feedstocks that are different from woodchip, such as hydro-char derived hydrothermal carbonization green waste, or mix olive pomace sawdust. An experimental validation performed. num...

Currently, the use of fuel is increasing, it feared that fossil fuels will run out in near future and national energy policy make target new renewable to reach 23% 2025, especially those most widely used for electricity fuel. Energy from vegetable waste one solution produce biomass an alternative replace fuels. The potential at Indonesian, West Sumatra area very large, which solid rice husk agr...

The integrated gasification combined cycle (IGCC) is a power generation technology which combines clean coal technology with a combined cycle. The system modeling is significant for design, operation and maintenance of the IGCC power plant. However, the previous IGCC modeling methods only contained a simplified compartment gasifier model, which is useful to consider the heat transfer and chemic...

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal based power systems, including the KBR Transport Gasifier, a hightemperature, high-pressure syngas filtration system, and a gas cleanup unit. Designed to be at a sufficient scale to test advanced power systems and components in an integrated fashion, the PSDF provides data necessary for commerci...

Abstract. Utilizing date palm waste as an energy source is a potential low-carbon source, especially in areas such the Middle East. This study investigates air gasification performed downdraft gasifier. The aims to analyze impact of various parameter ranges temperature 600-900 ᵒC, flow rate 1.0 4.0 l/min, and particle size <2-6> mm on gas ratios producer gas. H2/CO ratio important which i...
