LT5065B - An iproving method of a burning process - Google Patents

Abstract

The invention relates to methods of burning process and can be used in boiler rooms, furnaces or for another fuel burning field. The methods comprises the following steps: supply with air or oxygen to maximum density of a burning gas at the moment of an open flame, forced mixing of a burning gas with air or oxygen. A canal for supply with air or oxygen has even distributed holes, a diameter of a mention canal depends of quantity of burning gas.

Description

The invention relates to heat generating and air or liquid heating devices and can be used in large boilers, domestic heating boilers, fireplaces, furnaces and any other fuel burning field.

Generally, combustion gases are not completely burned during combustion. When there is a lack of oxygen in the combustion process, the flammable gas is discharged unburned through the smoke outlet.

Known heating device described in Lithuanian patent no. 4588. In this unit, the combustion process occurs in two chambers. In order to increase the burning intensity, additional air is supplied to the second combustion chamber from below.

The combustion process described in this patent is not efficient enough to produce low thermal energy

The object of the present invention is to burn as little fuel as possible and to obtain as much heat as possible.

The objective is achieved by supplying air or oxygen to the point of maximum accumulation of flammable gas in an open flame, forcing the combustible gas with air or oxygen, and supplying the air or oxygen with a duct with evenly spaced apertures, diameter and hole arrangement are selected based on the amount of flammable gas.

The present invention is directed to the efficient combustion of combustible gas and the recovery of as much thermal energy as possible. The largest quantities of combustible gas are lost by burning solid fuels in various furnaces. A solid fuel combustion boiler was chosen to illustrate the method of improving the combustion process. FIG. Figure 1 shows a general diagram of the boiler; FIG. Figure 2 shows an air or oxygen supply tube.

The boiler consists of a housing 1 with a door 2 for supplying fuel to the combustion chamber 3, which is provided with a grate 4. The grate 4 contains solid fuel.

The bottom of the housing 1 has a lower air supply valve 5 with an opening control mechanism 6. An air supply tube 7 with a plurality of evenly spaced openings 8 is provided above the disposed fuel 8. The smoke outlet 9 is located in the wall of the boiler body 1 preceded by the smoke baffles 10. The arrows show the directions of air and smoke flows.

Boiler operation:

The combustion of the fuel in the chamber 3 is arranged on a grate 4. The combustion air for the fuel is obtained through the damper 5. The combustion of the fuel is slow. Flammable gas from the bottom of the fuel burns incompletely due to lack of oxygen and rises to the top when unburned. The part 2 of the combustion chamber where most of the unburned flammable gas accumulates is provided with an air supply pipe 7 with apertures 8 arranged in its surface area, which may be supplied with air or oxygen, and may be forced by air intensity of combustion process required. In this way, the tube 7 acts as a gas mixer. The intensity of the combustion process in this part of the furnace is indicated by the blue color of the flame and the air supply tube heating up to red 7.

Advantages of this device:

1. Simple installation by its design.

2. Little need for funds to equip.

3. Can be operated as spontaneous and forced air or oxygen supply.

4. Economic effect is achieved.

5. Very cheap and easy operation.

6. Increases fuel burn time.

This method of improving the combustion process is unique and convenient in that the air is supplied to the combustion chamber where it has the greatest need for combustion gas combustion.

For this purpose, an air duct is used to supply air to the combustion chamber where it is most needed. At the point where flammable gas is accumulated, holes are made in the duct. The holes in the duct are made to the extent necessary to aspirate or inflate air or oxygen to burn flammable gas. The location, diameter and number of holes may vary. Depending on the length, width and volume of the combustion chamber. The diameter of the ducts depends on this air demand. The duct can be made of the simplest metal pipe whose diameter will depend on the amount of air needed to burn the flammable gas. The hot duct still serves as a gas burner.
