The time has passed when a private house could be heated in one way - the Russian stove. Today, civilization has reached the owners of suburban real estate. Now a person has the opportunity to equip his home in such a way that life in it is comfortable and convenient. You can try to implement the plan in more modern ways, which today are very controversial.
Heating options
Improved materials and technologies make it possible to equip the heating system in different ways, because the following can act as a coolant:
- antifreeze;
- steam;
- water;
- gaseous substance.
The choice is quite extensive, therefore, having familiarized yourself with the pros and cons of each option, you can choose the best one for yourself. Brown gas, for example, is also used today in the heating system. It is also known as green gas, oxyhydrogen or brown gas.
What is Brown gas
In order to determine what this gas is, you need to go a little deeper into the theory. The described substance is an odorless and colorless explosive gas , which consists of one part of oxygen and two parts of gaseous hydrogen.
Today, heating a house with hydrogen is considered a know-how that has not found wide distribution, but has already managed to attract the attention of consumers and win their recognition. However, to this day discussions are underway on whether it is advisable to use this method for a heating system.
Disputes revolve around two issues, one of which is security. Some emphasize that hydrogen is explosive. The second question is expressed in the cost-effectiveness of obtaining the product. There are doubts as to whether Brown's gas is worth the costs that go into obtaining it.
Conclusion
Brown gas for heating a home is a mixture of oxygen and free hydrogen, which is obtained from water by an electrolytic reaction. Water, the formula of which is known even to children, is oxidized hydrogen.
The chemical elements in the composition are individually active, and hydrogen burns well and is considered an energy carrier. Oxygen supports combustion. That is why this idea, which consists in splitting cheap water, is so popular today.
Brown gas production for heating
In order to understand where the described gas comes from, it is necessary to consider a device called a generator. It is used to produce gas, which is so actively discussed today by many experts. This invention provides a reduction in the cost of producing hydrogen and reduces the amount of harmful emissions.
Water is split under the influence of alternating current; as a result, independent components are obtained. Brown's gas generator allows you to split water, for which it is necessary to spend 442.4 kilocalories per mole. This indicates that 1866.6 liters of detonating gas can be obtained from 1 liter of water. Reacting with oxygen, hydrogen returns energy 3.8 times more than the cost of its production.
If hydrogen is produced using this technology, then it can be used to power buildings and buildings. Brown gas heating is not so common today, because this approach is quite new. The production of hydrogen boilers is only gaining its popularity, and in the Western and Russian markets such products are only just beginning to appear.
DIY generator making
Do-it-yourself Brown gas can be obtained by assembling the generator. The cost of such equipment is overstated, and the efficiency rarely exceeds 50%. To carry out the work, it is necessary to purchase some components, among them it is necessary to highlight the capacity where distilled water will be poured. It will enter a sealed container with a dielectric, where a set of stainless plates is located. They must be connected to each other through an insulator.
A voltage of 12 V must be applied to the stainless plates, this will allow the liquid to decompose into gases. But the most effective way will be to supply alternating current with a certain frequency from the generator. In this case, instead of direct current, you can use a pulsed or alternating, achieving increased efficiency of the installation. And to build this design you will need:
- stainless tubes of different diameters;
- PWM controller
- capacity.
Care must be taken to have stainless steel sheets.
How the design works
The described invention of Brown, which allows gas to be obtained, works according to a certain algorithm. When the generator is operating, voltage is supplied to the PWM, and the regulator generates voltage with the desired frequency. The gas production efficiency will depend on the frequency.
Voltage is then applied to stainless tubes or plates where water is located. Under the influence of current, rattlesnake is released in them. She through flexible tubes enters the capacity of the dryer, from which it passes into the air supply circuit. Such Brown’s invention, which allows gas to be obtained, can be used for heating:
- country houses;
- garage cooperatives;
- other premises.
To use such a device, it is necessary to remake a gas or solid fuel boiler. You can use tap water for the unit if it does not contain heavy metals. The best effect can be achieved using a solution of sodium hydroxide, which is added to distilled water. For 10 liters of water you will need 1 tablespoon of sodium hydroxide.
Generator Specialist Recommendations
Brown gas can be produced using a self-made generator. Many home masters wonder what metal to use in the assembly process. Some believe that only rare metals can be used.
Experts say that you can stock up on any stainless steel. Excellent results can be achieved if ferromagnetic steel is used; it does not attract debris particles. When choosing a metal, it is better to give preference to stainless steel, because it is not subjected to oxidation.
If you are interested in the question of how long the plates of electrodes are ready to serve, then you should know that there is no need to change them, because during operation they are not destroyed. For preparation, before welding, they must be washed well in a soapy solution, and then treated with an alcohol-containing substance like vodka. If you decide to make Brown’s invention, gas that allows you to get, you will need to drive the cell for some time, replacing the dirty water. Repeat this procedure until the water has washed the dirt. If the liquid is clean enough, the installation will not overheat.
When the electrolyzer was assembled correctly, when it is used, the plates and water will not heat up. The cell should not be heated more than 65 ° C. If this parameter goes beyond the norm, then the plates will be covered with dirt. Removal will have to be done with sandpaper, and as an alternative solution, replacing the elements with new ones.
In conclusion: specialist advice to home masters
When making Brown’s invention, gas that you can produce, you must place the electrodes in a container of water. The larger their surface area, the higher the productivity of the installation. Steel plates can be used which are fixed to the dielectric base.
The electrodes should be placed in a container where salt is added to improve the reaction. A gas tube is discharged through the lid, which must go into the second vessel. It should be filled with water at 2/3. The second tube from this tank is connected to the burner. Voltage is supplied to the electrodes from the transformer, it is important to control it with a multimeter.
