Wood gas vehicles: firewood in the fuel tank - LOW-TECH

Jan 18, 2010 · The fuel for a wood gas car consists of wood or wood chips (see picture on the left). Charcoal can also be used, but this leads to a 50 percent loss in the available energy contained in the original biomass. On the other hand, charcoal contains more energy, so that the range of the car can be extended. In principle, any organic material can be

While the production costs and logistical benefits of biomass pelleting have been widely discussed in the literature, the downstream economic and environmental benefits of processing pelleted biomass have been largely neglected. To investigate those benefits, we performed a comparative techno-economic analysis and life cycle assessment of producing ethanol using loose and pelleted forms of

Combined cycle power plant - Wikipedia

A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy.On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant.The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant.

Cogeneration - an overview | ScienceDirect Topics

During combustion, a fossil fuel can reach temperatures above 1000°C, and it is a bad use of its energy quality, for example, to utilize it exclusively to generate hot water for heating. On the other hand, cogeneration systems use fuels for high-quality energy generation, such as electric power and, in addition, a low-level thermal energy, but

Review on Ammonia as a Potential Fuel: From Synthesis to

Ammonia, a molecule that is gaining more interest as a fueling vector, has been considered as a candidate to power transport, produce energy, and support heating applications for decades. However, the particular characteristics of the molecule always made it a chemical with low, if any, benefit once compared to conventional fossil fuels. Still, the current need to decarbonize our economy makes

Thermal Power Plant Components & Working Principles

Combustion of fuel generates a lot of radiation heat which is transferred to water in the membrane tubes. Flue gases generated during combustion travel at high velocity across the convection bank of tubes thereby heating water through convection heat transfer. Hot water is sent to a boiler drum at high pressure through the feed-water pump.

Gasification - Wikipedia

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in

Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

Pyrolysis: A Sustainable Way to Generate Energy from Waste

Jul 05, 2017 · Lignocellulosic biomass is a potentially more valuable renewable resource that can be utilized effusively as a chief source of heat for cooking and can correspondingly subsidize the production of electricity, heat, biofuels and chemicals including solid fuel like char or carbon. Lignocellulosic residues are mixed and burnt with coal to generate electricity.

On the Response of Ultralean Combustion of CH4/H2 Blends

May 04, 2021 · Fluctuations in the fuel flow rate may occur in practical combustion systems and result in flame destabilization. This is particularly problematic in lean and ultralean modes of burner operation. In this study, the response of a ceramic porous burner to fluctuations in the flow rate of different blends of methane and hydrogen is investigated experimentally. Prior to injection into the porous
