Effects main operating parameters such as moisture content biomass, air flow rate i...

Penerapan konsep pemanfaatan limbah penggilingan padi sebagai sumber energi dapat mendukung peningkatan produktifitas terbarukan. Konsep eksergoekonomi dijadikan salah satu langkah untuk melihat peluang sekam penambah di sistem yang telah teritegerasi dengan gasifier. Specific Exergy Cost (SPECO) metodenya, dimana metode tersebut menggabungkan analisis eksergi dan ekonomi menerapkan biaya ke da...

Rubber wood (Ficus elastica) is one the biomass waste that can be used as raw material for a gasification process and has a calorific value of 4,069 cal/gram. Gasification is a process to convert a solid fuel to syngas (CO, CH4, and H2) through a combustion process using limited air between 20% to 40% of air stoichiometry. Depending on the direction of airflow, the gasifiers are classified as u...

In spite of the past few decades, gasification of waste is being used in the developed countries. Reducing the space for landfill sites, producing fuel from waste, as well as avoiding negative impacts of landfilling, are of advantages of gasification. The research was aimed at feasibility study of application of Tehran municipal solid waste (MSW) gasification in addition to understanding the wa...

The efficient use of renewable energy is receiving more and attention in the context “carbon neutrality” peaking”. For a long time, biomass has been used less efficiently as source, but with development fluidized gasification technology, it can play an increasing role industrial production. A bed gasifier strong nonstationary process due to its complex energy–mass exchange, analysis reaction pr...

Crops can also be grown for energy could produced in large quantities, and likely to become the most popular future. One of widely used renewable source heating is biomass form fuel wood, charcoal, agriculture residues etc. A lab model Fluidized Bed Gasifier (FBG) handling low density leafy materials like rice husk, saw dust, bagasse, tree leaves was developed. The performance study gasifier de...

Coal and biomass pyrolysis and gasification has gained importance in the last few decades for synthetic fuel synthesis, which is a promising solution to the current energy crisis. Efficient fuel feed is necessary to the coal and biomass utilization processes. Common gasification systems employ large-scale slurry feeders to inject the fuel into the gasifier vessel. The presence of excess water i...

The model has been developed by considering two distinct zones in the downdraft gasifier: pyro-oxidation zone and reduction zone. The process in the pyro-oxidation zone has been solved based on the chemical equilibrium consideration considering water gas shift reaction and methanation reaction. The composition of different species (H2, CO, CO2, CH4, H2O, N2 and Char) and the temperature of the ...
