Energy from non-conventional resources like biomass would be crucial in meeting the growth targets in the power sector. Biomass is the most commonly used domestic fuel and for independent power plants. Based on up-to-date combustion technologies, biomass and waste supply approximately 4.5 EJ (105 Mtoe) of direct heat to the industrial and residential sectors, and 2 to 3 EJ (47 to 70 Mtoe) of he...

This paper presents the debugging test of biomass circulating fluidized bed gasifier in a rice mill factory Jiangsu Province. The main process system is reported. typical problems during period are analyzed, including blockage primary cyclone separator, loop seal, inventory leakage blast cap on air distribution plate, feeding tube coking, and large fluctuation pressure. Reasonable improvement c...

This work presents the modeling and thermodynamic analysis of two novel small-scale polygeneration systems that are capable simultaneously converting residual biomass to methanol (MeOH), electricity, heat a CO2-rich stream for agricultural greenhouses. The first system is based on downdraft gasifier, while second relies dual fluidized bed (DFB) gasifier. Both configurations leverage H2, O2, ele...

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 ...

This work presents the hydrogen production from steam gasification of palm kernel shell (PKS) at 700 C in the presence of 5% Ni/BEA and 5% Fe/BEA as catalysts. The steam gasification was performed in two-staged reactors to evaluate the effect of calcinations temperature and the steam to biomass ratio on the product gas composition. The catalytic activity of Ni/BEA catalyst decreases with increa...

It is well known that fossil fuel combustion has tremendous negative impact on ecology and global climate. It is non renewable as well. The present rate of technological and economic growth of a country may be unsustainable due to rapid consumption of fossil fuel like crude oil, natural gas or coal. Thus people search for viable renewable energy sources like biomass, hydropower, geothermal ener...
