Wood Gas - The Future Biomass-Derived Fuel at Krzy

's suppose, namely you own a harvest. You produce grain and have a lot of fodder. You'd like to make your energy aboard site from the biomass you have available. You might vegetation your fields with rapeseed alternatively canola and generate biodiesel. But you'd absence to obtain methanol and lye premier, since either of them can't be made there! And you tin use your biodiesel merely in compression ignition (diesel) engines. And what whether you have an old genset powered by spark-ignition (petrol / gasoline) engine? I calculate I might have a solution as />
You'll make use of a technology that's extra than 200 annuals old. It's greatest evolution took location during World War II in 1940s in Europe. At that time most of petroleum-derived fuels were used by military and there was not fuel left for civilians. So they made their own oil, the lumber gas from lumber or charcoal. In some countries 95% of civil transport (trucks, buses, even fishermen's boats) were fueled with this gas.
What is this wood gas? From chemical point of view it's a mixture of combustible carbon monoxide (CO), hydrogen (H2) and methane (CH4), dilluted with some water vapor,[link widoczny dla zalogowanych], carbon dioxide (CO2) and nitrogen (N2). This gas can be accessible used for virtually every internal combustion engine. Well... besides for the most modern ones, they'd require to have their electronics to be modified.
How wood gas is made? When you heat wood it is pyrolysed,[link widoczny dla zalogowanych], i.e. always the tars vaporize. When you join some oxygen, the carbon bound among the wood cells is burnt to carbon dioxide. The vapors scald too. When those burnt gasses pass via a wafer of very hot char, they are depressed to carbon monoxide and hydrogen. A small amount of methane is also produced. When the gas is cooled and cleaned of anybody tars and particles, it can be used in inner combustion engine, boiler or any other device!
What do you need to produce your own wood gas? You'd need a device that's shrieked gasifier. It consists of fuel hopper, gasifying room and a set of filters. It's very easy to construct, the human during WWII made it out of old water heaters and matter like that.
Is wood gas secure? Well, if you don't inhale it, you'll be OKAY. Carbon monoxide is very noxious and poisonous, so remind namely required while using wood gas. From the engine point of outlook, if it's neat, it's secure. The tars might abbreviate inside the engine, case in point on valves, which might reason the engine to fail. The particles would probably break the adjoin surfaces on pistons and cylinders. If the gas is too hot the engine will not work (peppery gas is reduced and has small energy content per unit volume), merely it will not injure it.
Any drawbacks? One that's value mentioning. Petrol engines will suffer 1/3 power loss -- the wood gas does have small heating worth. Diesel engines will no suffer such power wastage, since they go on stratified fusions and because of that you can introduce more wood gas to revive the power wastage. You'd need to depart some small amount of diesel to be injected to the cylinders to kindle the wood gas.
Interested? One liter of petrol / gasoline can be replaced with 2.5 - 4 kg (5.5 - 9 lbs) of wood. How chilly is that!
