How to build a Backyard Waste Oil Burner Powered Water Heater to produce Free Hot Water for your Home

    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.

    • How to build a Simple Homemade Wind Generator from Old Ceiling Fan ,Microwave Oven Parts ,Old TV Antenna and other free junk
      This project goes over the build of a homemade wind generator built from random junk ceiling fan ,microwave oven transformer ,office chair, an old piece of a TV tower, and some random electrical stuff. The blades are also from an old ceiling fan .It is extended with some wood and fibreglass on it to make it stronger. A scrap piece of pipe is attached as a shaft to the hub of the turbine. An office chair frame which can move freely is welded to the pole/post of the turbine. This is welded to an old TV Tower. 4 magnets are glued on the hub. The frame of an old microwave oven transformer is cut .Its core is exposed and that is welded onto the brackets. The magnets pass over the transformer core and induction takes place creating electric current. We can use that current to charge a battery or to power lights or whatever. A multi transformer setup would generate more power. We hook up a rectifying diode to convert from AC to DC and some capacitors which can even out the voltage and give us direct current. Also a diode to block the current from the battery to go up back up to the generator. This set up can charge small batteries. A piece of sheet metal is welded onto the bracket of the ceiling fan. Four magnets are spaced apart and aligned along their respective poles in north-south directions and glued to the bracket using 2 part epoxy. To generate more wattage from the wind generator ,we use an old 120V DC lawnmower motor. Because we have multiple poles, we have magnets that are really close to the armature, this is a way better motor to use. The only downfall of this is that it has brushes, eventually it's the brushes are going to wear out, you probably get a few years out of it before you need to replace those. This motor would probably put out about 100 watts.

    • How to build a Homemade Micro Wind Turbine for under $50 that can be mounted anywhere
      This project goes in the detail on how to build a mini wind turbine..The wind turbine is a nice addition to your solar generator system for times when it’s cloudy and you are not receiving as much sunlight as you normally First step is to build some cheap PVC blades, what kind of motor we're going to be using and how we're going to attach this to the motor. We are making six blades or rotors here.What we want to do is we want to cut our PVC pipe to length first. Once you've got it cut to length, then you want to take your your straight edge again and and Marco line down the center and cut it in half. Make sure that you do that on both sides. One on this side, one on this side. And that they're perfectly in the middle so that you'll get two even sides. We need to cut a small little block down at the blade end, where we are going to put a drill hole and put a screw through it so that it attaches to the hub.On the top of the blade, we're going to cut away some of the material to resemble a swept wing, kind of at an angle. These are 14 inch long blades that is attached to the hub using set screws attached to the motor. The 12V motor used here is a 300 RPM geared motor which would be its maximum speed and it produces 600 milliamps when its fully loaded. The motor is placed inside a One and half inch PVC pipe ,another PVC Tee is connected from where the wires will down to the bottom where another 7 foot pipe that act as the tower or pole. The end of the pole goes into a shower drain which is then attached to piece of wood that acts a solid base. For the YAW system at the back end,a tail vane is made of a cheap flashing material that is bolted between an 8 inch piece of PVC.Put a hole through the middle of it with a bolt in between so that it can't move anywhere. We use an an old OSB for the base, size is about seven inches square. And then I just have a piece of treated lumber on the bottom. It's attached to this ball bearings so it can spin around. The Shower drain PVC is placed in the middle through some ball bearings. Route the wiring down through the hole for to connect to the charge controller. Next step is the wiring through the piping.We just need to connect these terminals to the appropriate sides of the motor.
