What are the differences between combustion and gasification?
Combustion involves burning a substance in the presence of oxygen to produce heat, carbon dioxide, and water. Gasification is a process that converts organic materials into a syngas (mixture of hydrogen, carbon monoxide, and methane) in a low-oxygen environment. Gasification typically allows for more efficient use of the feedstock and can produce a cleaner syngas compared to combustion.
Where can you get hydrogen from?
Hydrogen can be obtained from various sources, including natural gas reforming, electrolysis of water, biomass gasification, and some industrial processes like coal gasification. It is also produced as a byproduct from certain chemical reactions.
How can wood fired electricity be generated sustainably and efficiently?
Wood fired electricity can be generated sustainably and efficiently by using advanced technologies such as biomass gasification or co-firing with other renewable fuels. These methods help reduce emissions and maximize energy output from the wood, making the process more environmentally friendly and economically viable.
Can you make your own hydroen?
Yes, hydrogen can be produced through various methods such as electrolysis, steam methane reforming, or biomass gasification. These processes involve breaking down water or hydrocarbons to obtain hydrogen gas.
What modes of combustion requires liquid or solid fuels to be converted to the gas phase or vaporized?
Modes of combustion that require liquid or solid fuels to be converted to the gas phase or vaporized include gasification and pyrolysis. In gasification, solid fuels are converted into a synthetic gas mixture consisting of carbon monoxide and hydrogen, which can then be burned. In pyrolysis, solid or liquid fuels are heated in the absence of oxygen to break them down into gas, liquid, and solid products.
