Measuring Gases Produced by Waste Gasification to Improve Control and Efficiency
Waste gasification is a type of waste to energy process where waste material is used as a fuel to create heat, electricity or other chemical products. Specifically, in waste gasification, the waste material is decomposed in such a way to produce gaseous products, often known as syngas, a combination of hydrogen, carbon monoxide and some carbon dioxide.Conventional incineration uses heat and ...

Green Energy: From Waste to Syngas Production
Syngas production from waste gasification is one way to produce renewable energy. However, varying waste compositions can make gasification challenging to control, resulting in inconsistent syngas compositions. Closely monitoring gas composition and adjusting process conditions during gasification can ensure consistent, high-quality syngas production. Infrared sensors are the ideal solution for ...

Converting waste into valuable resources with the Gasplasma process
Abstract This paper reports on a novel process development to convert waste into renewable energy using gasification. Advanced Plasma Power (APP) has developed an advanced thermal conversion technology, (Gasplasma ), capable of treating a wide range of organic and inorganic wastes. In the two-stage thermal process, the fluidised bed gasifier (FBG) converts the waste to a crude syngas containing ...

Hydrogen-rich synthesis gas production from waste wood via gasification and reforming technology for fuel cell application
The purpose of this study was to establish a fuel process for an advanced power generation system in which hydrogen-rich synthesis gas, as the fuel for the molten carbonate fuel cell (MCFC), can be extracted from biomass via gasification and reforming technologies. Experiments on waste wood gasification were performed using a bench-scale gasification system. The main factors influencing hydrogen ...

Preliminary studies of lignocellulosics and waste fuels for fixed bed gasification
This study was carried out to understand the decomposition behaviour of a range of biofuel and waste feedstock during gasification in a downdraft gasifier. A laboratory scale large sample thermogravimetric analyser (LSTA) is used which allows the data on burn-out characteristics of different fuel particles to be measured under agitated conditions. The conditions chosen simulate the combustion ...

Plasma resource recovery technology –converting waste to energy and valuable products
Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired eductor ...

Air gasification of Malaysia agricultural waste in a fluidised bed gasifier
Hydrogen production from agricultural waste has been investigated experimentally using a bench-scale fluidised bed gasifier with 60 mm diameter and 425 mm height. During the experiments, the fuel properties and the effects of operating parameters such as gasification temperatures (800?900?C), fluidisation ratio (2.0?3.33 m/s), static bed height (10?30 mm) and equivalence ratio (0.16?0.46) were ...

Small-scale heat and power at B.C. mills
Fred Scott introduced the B.C. Bioenergy Network (BCBN) as an alliance between Pristine and Nexterra Energy Corp. BCBN is a network of 15–20 individuals, with 10 MW power plants located across B.C. at mill operations in forest communities. Nexterra has developed a proprietary gasification technology that “takes wood waste material and [produces] clean burning synthetic gas or syngas,” Scott said. ...
