This projects goes over the build of waste oil powered free hot water heater for your home .This converts an old used domestic water heater to run on waste oil, engine oil or cooking oil. With as little as one liter of waste oil, this heater gives twice the heat output than a domestic electric powered water heater .As waste oil is free, this is more economical than running on gas or electric.
The setup of this waste oil heater is very simple and easy. We have a waste oil burner that is placed under the domestic water heater. The burner is connected to a blower from a car. This blower is powered by a 12V battery charger . The burner is also connected to a drip feed waste oil pipe through a small pipe.
The oil feed from a suspended tank, which gives it a gravity feed dribbles into the inlet pipe on the burner and it is simply blown into the burner by the force of the air from the blower. To control the oil flow ,we have a valve on the oil tank.
The cold water comes into through the inlet hose at the bottom of the tank . From there burner just fires the heat up through the center of the heater as it would normally if it was gas fired. The hot water comes out from a outlet hose at the top of the tank.
The waste oil burner is made out an old fire extinguisher bottle. The beauty of using extinguisher bottles is you don’t have to worry about any flammable gases in them, and the metal seems to be quite durable.
Make sure that the air and the fuel enter the bottle at a slight angle in order to create some swirling. This makes sure that the air and the fuel mix and will burn completely. And also that the bottle is kept hot so that the liquid oil will vaporize and the gas will burn.
The inlet pipe for the waste oil and the blower is positioned at 25 to 35% of the way up to the bottle. The inlet pipe has a small bend in it so as to promote swirling within the bottle. This is important in keeping the bottle hot and self sustaining. The burner has a clean burn with almost no smoke.
The output of the oil burner can be controlled by the amount of waste oil being dripped into the burner and by the amount of air blown into it. This oil gas burner is more powerful than a gas burner and the heat produced can overpower the heat sink threshold of the water heater . A vent line is installed on the system so that any build up pressure can be released. Apart from heating hot water , this set up can be used for space heating , pool heating or garage heating.
- DIY Video :How to build your own Homemade Lumber Mill from Scratch .This projects goes over the build of a cheap homemade lumber mill using materials around your home This mill has a 12 inch saw blade purchased from Home Depot that cab do cross cuts, or it can do longitudinal rip cut.I am gonna be cutting the long direction on the word. First step is building the rollers. Four rollers are made out scrap materials lying around. The wheels are made of polycarbonate material .These are adjusted on a drill to ensure that they roll smoothly on the pipes. Next step is the build the tracks.Here I use 2 old steel pipes and welded to make a long one. 3 more pipes are welded on top of those 2 long pipes horizontally to give stability. Make sure the pipes are all lined up . 2 rolling carts are made from the leftover pipes tha slides across the pipes.Make sure these are parallel to each other.4 sliding pipes are bolted on these carts. 4 pieces of pipes are welded on top of these rolling pipes that are paralled to the horizontal pipes below .They act as a crank that can pull the sliding pipes. Threaded holes are put along the pipe that connects the sliding pipes.2 cables are connected in opposite ways to a small spring pulley system that can help sliding pipes move vertically up and down when the top crank is rotated. The Saw Blade is attached to a steel rod.The blade is attached to a washer on the other side to ensure it doesn't fly off. The axle is passed through a square metal box which is bolted using a bearing on both sides. The motors attaches to the top of the box mount .A pulley is then attached to the metal rod from the motor using a small wheel. The next step is to take whole side assembly thing attach it to the cart so it can pivot. Ball bearings are attached to the box on both sides.This must be placed at a very specific distance away from the blade. So that when I flip it the the edge of the blade will line up so it cuts clean without cutting deeper into the wood and without not cutting far enough and leaving it still attached.When its swiveled it will pivot the blade perfectly. Next step is make take the whole motor and blade assembly and attach it to our rails so that it can slide and rotate . We attached 2 pieces on both sides of the motor blade assembly to ensure that the system stays perfectly straight while cutting horizontal or vertical. https://www.youtube.com/watch?v=KtL7LoFeTyg https://www.youtube.com/watch?v=txUgR7kYpgI https://www.youtube.com/watch?v=LUxo36NebVA https://www.youtube.com/watch?v=IOEHT1UrbKM https://www.youtube.com/watch?v=deblj68KZug https://www.youtube.com/watch?v=Axo2w5_qHd8 https://www.youtube.com/watch?v=_uhvSBLY0Xc https://www.youtube.com/watch?v=5sPu_TcUtyU
- How to build a Homemade Multi Use Water Purifier that uses no electricity .Works as Water heater and stove burner too….This project goes into the build of a simple and cheap two stage DIY water filter.Also doubles as a stove burner. The materials needed for this build are some bricks,bottles,copper coil,activated carbon,sand,gravel I got the sand and activated carbon water filtration part on the far left. In the middle, I've got it heated in a copper coil running on isopropyl alchohol. The purified water is coming out on the right side. The first step is to make the 1st stage filter. We take a 2L bottle cut in half, drilled a quarter inch hole on the bottom and drop in a couple of cotton balls and pack it in there. Next step is to add the activated carbon,sand and gravel.Rinse all of them before adding . Align the bricks and place the cans on top. Place a small tin with the isopropyl alcohol inside the middle can. A copper coil is inserted into the middle can and connect between the first can and the water bottle. Add the sand mixture filter bottle on top of the first can below the copper pipe. For the first can the one that holds the activated carbon filter,just remove the label and drill one small hole at the bottom. Then for the second cam that holds the copper coil, you cut down the top, take about a third of circumference off and cut about two thirds of the way down. Then put one small notch on the top and a hole down below for the coil. To make the copper coil just wrap it around from top to bottom in a smallcan, push the can out and leave about a foot on either side. Notice I added a couple of bricks and pointed the end of the copper tubing down directly into the can so we won't lose hardly any water and make sure to drill those steam vents so the pressure doesn't build up. Make sure to drill vents on the bottle so that the pressure doesn't get build up. Pour the alcohol under the coil and fire it up. Just put a little in ,you don't need too much. A full glass of water gets purified in three to three and a half minutes. This gravity fed two stage water filter should take care of pond water stream water swamp water, just about any water you can think of. Don't try using this without the heavy sand gravel and activated carbon in there or the water will backflow and it may spray out. An easy way to store this filter when you're not using it is just save the bottom half of the two liter bottle you cut in half and drop the filter in it ,holds it perfectly. This cheap 2 stage heated oil water purifier can also be used to both purify water and cook at the same time.
