Description

Device for combustion of gas with higher content of hydrogen

Technology area

The invention relates to device for combustion of gas with higher hydrogen content, especially for production of heat and hot water, in facilities designed for home and small spaces, designed primarily for end consumers.

Present condition of technology

Currently, the device for production of heat and hot water depends on the combustion of solid fuels or gas, where the combustion medium must be transported to the device and stored. There are also known some prototypes of boilers for combustion of hydrogen which has a gas storage or the boilers produce gas for immediate consumption by the steam electrolysis in the generator. These prototypes, however, still do not address the use of heat in the production of gas with higher hydrogen content and the problem remains in the form of frequent failure of such devices because of their insufficient cleaning of gas destined for incineration and the frequent failure of the combustion chamber from the reasons due to the high temperature during the combustion of gas with higher hydrogen content.

Principle of technical solution

The above deficiencies are largely solved by this device for combustion of gas with a higher hydrogen content of the present invention where the components are ranked in order of generator, heat exchanger, separator tank, filter tank and the combustion unit. This order in itself is known, but this technical solution aimed to modify these individual items of device to eliminate the above disadvantages of the device.

Exchanger consists of a tank and heat exchanger spiral, which is stored in the exchanger tank. Because in the spiral there is the hot water with gas from hydrogen generators, this mixture in a spiral is under tension. The outer shell of the spiral according to this technical solution is non-conductive. The advantage of this solution is that a mixture of water and gas from the generator is hot and it heats the water in the heat exchanger tank. This water is returned here from the radiators. Thus a system of heat transfer is used here before the gas combustion.

Separator tank consists of a water input and output, gas outputt, fitting of level sensor, output of gas and purifying sieve. Water with gas after the cooling in the exchanger is blown under the purifying sieve which prevents from excessive bubbling of gas, while under the puryfying sieve the outlet of gas-free water is placed and the gas has its output created above the puryfying sieve in the top of the separator tank.

From the separator tank the gas with higher hydrogen content and remaining water goes into the filter tank. The filter tank consists of a gas input and outlput, the output of condensing water and condensing sieve. The gas enters the filter tank through the pipe that goes under the condensing sieve, on which the water contained in the gas condenses. The gas passes freely through a sieve and gas outlet gas and purified gas passes into the combustion chamber. The excess condensate that can be recycled leaves the filter tank through the output of condensed water.

The combustion chamber is filled with water and insideof the combustion chamber there is a four-level ( four-story ) labyrint for water heating. In the first stage the gas is combusted when the flame touches the ceiling of the combustion chamber. Because the water is around the labyrinth, the ceiling of the combustion chamber does not burn. In the ceiling of the combustion chamber there is a pipe for combustion products exhaust that carries hot combustion products and that forms a second level of the labyrinth. The third and fourth level has a recooling function of combustion products to leave the combustion products/gases the labyrinth at a temperature below the temperature of the fluids in the combustion chamber.

List of pictures on the drawings

The invention is further illustrated by the drawings, where Figure 1 shows a diagram of connections of parts of the device, Figure 2 shows the heat exchanger , Figure 3 shows the separator tank, Figure 4 shows the filter unit and Figure 5 shows the combustion chamber. Example of technical solution conduct

The components are ranked in order of generator 1, heat exchanger 2, separator tank 3, filter tank 4 and the combustion unit 5. Exchanger 2 consists of a tank 10 and heat exchanger spiral 1 1, which is stored in the exchanger tank. Because in the spiral there is the hot water with gas from hydrogen generators, this mixture in a spiral is under tension. The outer shell 12 of the spiral !i according to this technical solution is non-conductive. The advantage of this solution is that a mixture of water and gas from the generator is hot and it heats the water in the heat exchanger tank 10. This water is returned here from the radiators. Thus a system of heat transfer is used here before the gas combustion.

Separator tank 3 consists of a water input 20 and output 21, gas output 22, fitting 23 of level sensor, output of gas and purifying sieve 24. Water with gas after the cooling in the exhanger 2 is blown under the purifying sieve 24 which prevents from excessive bubbling of gas, while under the puryfying sieve 24 the output of gas-free water 2J_ is placed and the output of gas 22 is created above the puryfying sieve 24 in the top of the separator tank 3.

From the separator tank 3 the gas with higher hydrogen content and remaining water goes into the filter tank 4. The filter tank 4 consists of a gas input 30 and output 3_i, the output of condensing water 32 and condensing sieve 33. The gas enters the filter tank through input 30 consisting of the pipe that goes under the condensing sieve 33, on which the water contained in the gas condenses. The gas passes freely through a sieve and gas output 3J_ and purified gas passes into the combustion chamber. The excess condensate that can be recycled leaves the filter tank 3 through the output of condensed water 32.

The combustion unit 5 is filled with water and insideof the combustion chamber there is a four-level ( four-story ) labyrinth 40 for water heating. In the first stage, in the combustion chamber 40a, the gas is combusted when the flame touches the ceiling of the combustion chamber 40a. Because the water is around the labyrinth, the ceiling of the combustion chamber does not burn. In the ceiling of the combustion chamber 40a there is a pipe 4_1 for combustion products exhaust that carries hot combustion products and that forms a second level of the labyrinth 40. The third level 40b and fourth level 40c of the labyrint 40 has a recooling function of combustion products to leave the combustion products/gases the labyrinth 40 at a temperature below the temperature of the fluids in the combustion chamber. Industrial efficiency

The above-described device can be advantageously used to obtain thermal energy for retail customers without the need for storing a mixture of hydrogen and oxygen and without the need for long heat distribution from the producer to the customer.
