VENOT-HC, iSociet6 Anonyme, Avon (France) Combustion chambers

The invention relates to an improvement in combustion chambers, due to the better distribution of the combustion flue gases, a very quiet and even operation Combustion and effective protection of the refractory linings is achieved.

They are combustion chambers with tangential gas supply began in which the air-fuel mixture after a pre-combustion is introduced into the flint. These chambers have a single tangential feed, which disadvantageously reduces the flame is driven onto one of the inner walls of the chamber.

The invention relates to a combustion chamber from special training in which the actual combustion chamber and aie mixing chamber in the form of two consecutive compartments different volumes are formed. The combustion chamber has four gal. inputs, which are tangential and opposite in pairs are arranged and consist of jackets and connectors of suitable size with fire-resistant fittings Can.

Further advantages, details and features of the invention result from the following description, on the drawing the invention is shown for example, una zv.ar. Show

Fig. 1 is a longitudinal section through which the combustion and chimneys containing the mixing compartment,

FIG. 2 shows a section in a plane β-β of FIG. 1 to illustrate the tangential gas feeds to the mixing compartment,

Fig. 3 is a longitudinal section through the chamber to illustrate the return of the Breath gases and vapors, and

4 shows a section in a plane G-C of FIG. 1 to illustrate the tangential gas feeds into the combustion chamber.

The system according to the invention works as follows: A burner 6, with combustible gas, e.g. coke oven gas and with a just enough air is fed in for chemically neutral combustion is at the end of the first cylindrical compartment arranged and creates a very hot flame through combustion without excess air inside. The burner is through Combustion air cooled which flows through at 7fc after being under Pressure was applied.

The hot flame develops inside this first There are two tangential openings in the compartment and in order to prevent its radiation from affecting the inner wall too much 2 and 3 provided, in the same plane and in the same .Direction, but are arranged offset by 1bO ° and uurch üie a certain amount of oxygen-free gas is relatively lower Temperature flows. This gas is very often recovered and cooled raw combustion gases, flows

also under pressure and surrounds the flame in a vortex flow. The latter has a twofold effect, namely firstly to ensure a perfect air-gas mixture coming from the burner - therefore there are only negligible combustion jerks before - and secondly, to limit the rise in the temperature of the inner wall by means of a close exchange aer temperatures of the gaseous bodies.

all gases then flow into the second cylindrical compartment, which is arranged concentrically to the first, but has a larger diameter. Two openings 4 and 5 corresponding to the previous ones allow the inflow of a second quantity of neutral gas in order to terminate the entire mixing process of the gases to be generated and bring their temperature to their final chosen gradient.

By regulating the respective amount of in the two successive ones Incoming gases can affect the temperature in the interior of which are effortlessly kept even.

Of course, the described and illustrated jius guides can be modified without departing from the scope of the invention to deviate. Eo can have more than two tangential gas feeds be provided and the feeds can be arranged in different levels and in any number in each level uein.

The invention can be used in all those cases in which proper combustion in a practically neutral atmosphere and a pressurized neutral gas at the required temperature, without being switched on or used by Zuij'atzanlagen.
