How to build an Offgrid Wood Gasifier that can produce alternative free fuel

    This project goes over the build of a cross flow wood gasifier that powers a generator or a car or any kind of internal combustion engine using nothing more than wood scraps, paper, coal or any other organic materials. This unit was built in nothing more than an angle grinder, and a hand drill and parts that you can find lying around.

    这些设备正在利用一种名为气化的过程,您可以采用任何类型的有机生物质,真正的任何自然都是自然的,烧伤并通过加热它,您可以通过称为热解的过程将其分解为其基本元素。这产生了一种叫做合成气或木材气体的气体。在这里,我们在氧气贫困环境中燃烧生物量。并且这种热量通过足够的氧气持续到不扩散以点燃与周围材料的热量相互作用产生的气体是我们使用的过程来制造木质气体。

    出来的气体含有从木材中水分含量的水蒸气,也造成焦油和克雷糖。所以我们需要过滤出气体。并且使气体足够清洁以运行发动机的主要关注点是通过冷却下来。我们将来自压力罐的未过滤的气体连接到散热器中以使其冷却,然后进一步连接到填充有锯灰尘的铲斗以过滤。

    电抗器单元由旧的5加仑绘画压力罐制成。第一步是将其烧掉旧残留物和油漆。也烧掉内部容器。

    确保盖子上的盖子上的所有内容被移除并用插头或螺栓密封。取下盖子背面的橡胶垫圈。盖子表面上的孔覆盖有三个第八英寸螺栓。

    在锅的底部,我们将两个管道连接到进气口和SYN气体吸力输出。借助一个四分之一的英寸管法兰,这些管子紧紧地握在盆中。

    这air comes up from the bottom, the gasification happens in the middle of this reactor and the ash gets sifted to the bottom through a passive shaker grate. The output pipe is capped at the top to prevent the residue ash going out and small holes are drilled along the pipe to allow the wood gas to pass through.

    下一步是建造燃料实际坐在哪里的格栅插入物。炉排将距离锅底大约两个半英寸。格栅由带有压力喷涂罐的其他不锈钢容器制成。

    Grid of holes are drilled along the surface of the grate using a quarter inch drill bit. The grate is finally is inserted into the reactor pot chamber .

    盖子背面的垫圈被取出并用玻璃纤维绳替换,可承受温度高达2000度的华氏度。绳索使用垫圈水泥和炉子密封剂固定到位。盖子夹在适当位置,直到垫圈水泥干燥。

    下一步是构建冷却和过滤系统。为了让所有焦油和蒸汽凝回回它们的液体形式,我们使用旧的油加热器散热器,充当冷凝水捕手。从反应器中出来的气体连接到散热器,散热器使大部分热量从它们中脱离。

    We build the filtration system using a 5 gallon metal bucket to get the gas as clean as possible. The output pipe is attached to the bottom of the bucket using a flange. The bucket is filled with a filter medium such as wood shavings or sawdust that will trap any sort of particulates and get more tar out of the gas.

    An old car blower from a toyota is attached to the top of this bucket to get that gas up to the point where it can burn. The blower motor is supported with a old 10 tin can that is then secured at the center of top of the bucket .Another soup can is soldered to the 10 can on the side to attach the output hose pipe.

    We don’t want there to be enough oxygen to actually just burn all the material in there before we can extract the gases . So we are limiting this by using a one way gate valve . The one way valve is important to prevent flashbacks if too much oxygen is there inside the reactor .

    We load the reactor with wood sticks and put some starter down in there, which is just some cloth, some paper and a sprinkle some wood pellets on top just to give us something small to start off with. We pack the reactor leaving a spot in the center . The fans is turned on and we start the ignition process.

    • 如何构建一个螺母液压泵,该泵使用没有电泵送水。
      水是您可以拥有的最重要的资源之一,并将水放在您的财产中最高点,以便您可以将其存放并水水,您的花园和您的动物,果园是非常有价值的。This project goes over the build a water pump that can pump water uphill with no other external source of power except for the water flowing into it. If you have got a piece of land with an abundant source of water like a pond or a creek, a ram pump lets you get that water to a tank or a location at a higher elevation without using no electricity or fuel.RAM泵本质上是两种方式止回阀,一个称为废阀和另一个称为输送阀。为了让它开始,你只是暂时打开废阀,让水流。之后,它正在自己工作,以将水泵上坡泵在源极的升高之上。这ramp pump works by the principle of water hammer. As the waste valve opens, water flows into the pump and immediately out the valve. But as it picks up speed, the flowing water eventually forces the waste valve to slam shut. Now the water is stopped in the pump, it had kinetic energy, but now it doesn't. That means that kinetic energy was converted into pressure.Slamming a valve shut converts all the kinetic energy nearly instantly, creating a huge spike in pressure which opens the second check valve and forces water entering the pump into the delivery line. An pressure tank is included in the pump to smooth out those sharp spikes and pressure and provide a more even flow rate out of the delivery pipe, reducing wear and tear on the pump components.在这里,我们使用PVC气缸作为压力罐。随着输送管打开,它将允许恒定的水流量作为压力构建。如果您快速打开阀门,这将在其上保持一定的压力,使泵不会因压力损失而停止。以某种方式从源头到泵将水送到泵中,需要有管或管道。该管子是一个被称为驱动管的驱动管。这需要头部压力或升高。驱动管具有与废阀相同的尺寸。材料越坚硬,泵的效率越高。您可以使用钢或PVC管或柔性管。为了让水到我们所需的目的地,我们将需要有一个叫做送货管的东西。在这里,我们正在使用花园软管作为送货管。这是组装一个季度我的步骤nch hydraulic ram pump. The parts you need to build this pump are : Six one quarter close pipe nipples - This allows the components to be screwed close together and not have any extra gap between. Two three quarter pipe nipples 2 One and a quarter ball valves 3 quarter threaded union 2 One and a quarter PVC union 2 threaded PVC tees - threaded on all 3 sides A threaded spring check valve - This has a spring on the inside. That allows water to flow through one direction and not the other. A bushing that goes from one and a quarter down to three quarter. A brass or stainless steel swing check valve - This is threaded on both ends. And inside there is a little lever that closes on a swing motion. Teflon pipe tape to make sure things are tightened up and couple of wrenches.泵组件的第一步是采用Teflon胶带并将其放在这些一英寸和三个四分之一管嘴周围。这是在顺时针位置完成的,使得只要才能实际拧到该组件上,我们希望确保它们不会拧下或删除Teflon磁带。该管带将允许组件以更流体的方式拧紧在一起。它有助于在组件中创造更好的密封。Next step is take your one and a quarter ball valve and a pipe nipple and thread that together.Take the one and a quarter union and connect it to the other end of the taped nipples.Connect a tee to this unit with the help of another pipe nipple.接下来将弹簧止回阀连接到本机。您需要确保流量指向我们刚刚放在一起的组件。这些上有一个箭头,可以区分流动方向。通过乳头将另一个PVC发球台连接到阀门。螺纹衬套将在第二个发球区域结束时进行。在这三季度的衬套上,我们将把三个季度管道乳头中的一个。从那个管道乳头,我们将把另外三个四分之三英寸联盟放进去。A three quarter ball valve is connected to this end through another pipe nipple.We connect the swing brass/stainless steel check valve to the first PVC tee with the help of another pipe nipple. When connecting the check valve, make sure that the door or flapper is going to fall open from gravity. So it is going to screw on to this pipe nipple with the door hanging open.第二个PVC TEE与另一个管道乳头连接到压力罐。确保两个T恤面对相同的方向。要为泵和四分之一泵构建压力罐,您需要四英寸PVC时间表40管,四英寸联轴器,四英寸的插座,一个四分之一的螺纹衬套,四英寸盖,自行车内管。Take your angle grinder and cut a 17 inch long pipe from the four inch PVC schedule 40 pipe .Once the pipe section is cut, it's time to assemble the pressure tank.将联轴器内部与PVC水泥一起涂覆并粘贴到我们的17英寸管道内。当然它在那里真正的舒适。联接器的另一侧连接到螺纹衬套。Next step is to insert the bike inner tube into the pressure tank .Grab it from the underside and pull it enough that we can attach my pump to it. 用自行车泵开始填充管。泵直到整个管似乎紧张。将盖子放回顶部并使用PVC水泥密封它们。这last step is to attach your pressure tank onto this threaded nipple that is connected the second PVC tee on the pump. Next step is installing the ram pump near the water source .This one and quarter inch pump requires around eight gallons per minute to operate. The amount of water that you get at the top is increased as the pump size goes up.因此要启动泵,首先需要关闭输送管的球阀,并确保打开驱动管的球阀。您需要立即将废阀推下来,直到驱动管内的所有空气出来。水掉了该驱动管,并撞上止回阀以将其关闭。它创造了一个压力波,将驱动管击中备份。如果压力波找到气袋,则泵将停止。Start priming the pump by opening the valve manually couple of times until the pump starts to work on its own. After the pump has been running for a minute or two, you're gonna open up your delivery pipe valve out because the pressure tank now has enough pressure in it to push water uphill. https://www.youtube.com/watch?v=K8Fy__ThqpQ

    • How to build a simple and effective Multi Purpose Waste oil Aluminum Scrapping Foundry / Forge out of Scrap Metal
      这个项目的构建可转换waste oil powered aluminum foundry / forge made out of recycled materials. Waste oil burning does get more than hot enough to melt down aluminum, which has a melting point of about 660.3 degree celsius.这materials you need for this project are old 10 gallon propane tank for the foundry, air compressor tank for the waste oil burner, blower from a car , three eighth inch hose and a brake line for feeding waste oil from a bucket, 12V marine battery for powering the blower. 我们拿一辆汽车加热器鼓风机和房子在旧锡罐内部罐头。这焊接到汤可以和一个和四分之一英寸的时间表80管道。本质将空气送入燃烧器容器中。作为废油的燃料源是用带有黄铜闸阀的五加仑水罐供给的滴灌。它通过三个第八英寸软管和金属制动线连接到鼓风管。 这waste oil burner is from an old air compressor tank .It has a two inch cap on the top where we start the ignition and light the system. The pipe from the blower goes half an inch into the burner at an angle. This generates a cyclone vortex effect . We want to make sure that the oil and air are very well mixed together. In order to sustain combustion on something that's so difficult to ignite like waste oil, we have to have a source of heat so it can actually atomize, turn into a vapor where it will burn very easily and very effectively.从燃烧器的出口连接到铸造丙烷罐,通过带有旋转联轴器焊接的三英寸轴。这可以独立地旋转,使得铸造厂可以在杠杆的帮助下旋转到锻造模式。 我们标记并切割丙烷坦克的顶部,基本上形成了我们的铸造体。接下来,我们将需要在内部放入衬里,大约两个四分之一英寸厚。这充当绝缘体。在这里,我们使用50%的巴黎石膏混合和玩沙子。丙烷罐填充有混合物,气体压缩机浸没在中心以形成模具。在我们将空气压缩机脱离之前,我们让坦克静置24小时以固化。 Next step is to create the hole into the side of tank that will be the outlet of our waste oil burner. The hole is cut at a height so that the the aluminum wont run down and back flow into the oil burner tank. We place a three inch axle through the hole that is welded to rotating coupling . This coupling attaches to the outlet of the oil burner.One the other side of the propane tank ,we add a small lever system with a latch to manually put the foundry into a forge mode. A one inch water pipe is connected to the tank .Inside of that one inch water pipe is this bit of one inch shaft with a hole drilled in to accept a three eighths inch bolt. A rebar with a latch mechanism is welded vertically to this pipe. The latch is pulled to pulled and the foundry is rotated into forge mode. 这foundry sits on a cradle during the forge mode .The cradle is made out of two inch flat bar. The frame is constructed from one and a half inch by one and a half inch angle iron that I had laying around. 为了启动系统,我们使用一点抹布,将其戳进入油燃烧器点火口的入口。我们应用一点废物机油并开始点火。一旦火焰开始,我们将通过将其连接到12V电池来向我们的鼓风机电源施加电力。https://www.youtube.com/watch?v=l95fksaaoee.
