SU99936A1 - Burner to ensure combustion in household heating appliances gases with a calorific value below 1500 kcal / m3 - Google Patents

Description

In the burners of gas household heating devices, in which combustion takes place with a flame in the form of separate tabs, it was not possible to squeeze gases with a low calorific value, since the process of the combustion was unstable.

The burner described in this way doesn’t consistently burn gases of the specified quality in household heating appliances. This is achieved by such constructive execution of the burner, in which the outflow holes in its head are located between themselves at distances of no more than half of their diameter or are connected to each other. In order to raise the flame temperature, the burner head is made with an end arrangement of the outflow openings and is surrounded by a low shaft. In order to effect a flameless combustion of gas in the mine, a ceramic pasad is installed.

FIG. 1 shows a burner in a longitudinal section with an external one; c) T -; furs1; on

FIG. 2 - the same with the internal arrangement of the outflow openings; in fig. 3 - burner for gas-free burning. The direction of flow of gas and air into the burner is indicated by arrows, respectively, with the letters a and c.

The burner shown in FIG. 1, is made like burners used in sushi gas stoves, but Bneunie bodies differ from them, which does not have a removable head, and it works without prior gas replacement with air.

The upper part of the burner corus 1 is an irradiated head, which is a raziodedelny head, with 2 holes d: 1 gas outflow. The holes are located between each other at a distance of no more than half of their dialtetra or can be connected with each other, for example, by means of an external collar: l. Raspatggeliya tolovka vyiolpeya in one piece with the body of the mountain, tkn.

The burner shown in FIG. 2, valid with preliminary displaced g ch. Feature

This burner consists in arranging the outflow holes on the insert 5 in the end part of the burner and surrounding its hull with shaft 4. Combustion of the finished gas-air mixture in this burner takes place without access of ambient air. The direction of the jets of gas and air entering the burner is shown in FIG. 2 and 3, respectively, arrows with letters g and c.

In the described burner, equipped with a shaft, a ceramic nozzle 5 can be installed as shown in FIG. 3. In this case, the perforated insert in the mount serves to heat the gas-air mixture entering the sediments. Combustion of gas in a burner with a ceramic nozzle is also carried out without access of ambient air and is not accompanied by the formation of a flame (flameless combustion).

Subject invention

Claims (3)

1. A burner for ensuring the combustion in domestic heating appliances of gases with a calorific value below 1500 kcal / m with openings on its upper part for the outflow of gas or its mixture with air, so that the outflow openings are located at a distance of no more than half of their diameter or communicate with each other. 2. Burner according to claim 1, characterized in that, in order to increase the temperature of the flame by reducing the influx of secondary air to it, the burner is placed in the shaft or in the recess of the heating device. 3. Burner io p. 2, that is, so that the ceramic nozzles are installed in its mine.
