This paper presents a new method for measuring tar concentration in biomass-derived producer gas streams. This solvent-free method is much simpler than the evaporative method of the International Energy Agency (IEA) tar protocol. In tests on producer gas from a fluidized bed biomass gasifier this so-called dry condenser method yielded tar measurements with precision better than 5% and accuracy ...

Gasification involves turning organic fuels (such as biomass resources) into gaseous compounds (producer gas or syngas) by supplying less oxygen than is needed for com­ plete combustion of the fuel. Gasifica­ tion occurs at temperatures between 1112o and 2732o F and produces a lowto medium-energy gas depending upon the process type and operating conditions. Gasification of biomass resources is ...

Since fossil fuel subsidies entail significant economic, fiscal, social and environmental costs, more and more attention is being paid to phasing out fossil fuel subsidies. The OECD has recently completed a report quantifying the amount of both producer and consumer subsidies for their member countries, and some work has been implemented on analyzing the effects of consumer subsidy removal. How...

Abstract Biomass gasification is a thermochemical conversion process of solid biomass into gaseous fuel called producer gas that can be used to generate power and electricity. The consists around 47% Nitrogen (N 2 ), 24% Carbon Monoxide (CO), 16% Dioxide (CO 12% Hydrogen (H 1% Methane (CH 4 ). However, ) content in the reduces its heating values as N acts diluent because low calorific value (LC...

Biomass gasifiers convert the solid biomass to Producer gas that can be used for thermal, mechanical and electricity production. This paper deals with proximate and ultimate analysis of a number of biomass feed stocks like sawdust, pine wood, sal wood, eucalyptus and popular wood. These fuels have been used for the operation of 5 kW biomass gasifier installed at AHEC for electricity production ...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...
