Embodiment Construction

[0034] Referring to the above-mentioned drawings, numeral 1 designates the burner according to the present invention as a whole.

[0035] Preferably, the burner 1 comprises a head 2 where a combustion zone 3 is defined where the combustion takes place.

[0036] More preferably, the burner 1 is of the non-premixed type (mixing between fuel and oxidizer takes place directly on the head 2 rather than before).

[0037] More specifically, the burner 1 comprises a first fuel inlet 4 in which there is an inlet valve 5 for regulating the quantity of fuel supplied. Preferably, the first inlet 4 is defined by a conduit for conveying fuel 6 along which an inlet valve 5 is placed. The conduits for conveying the fuel 6 extend in the direction of the combustion zone 3 for feeding the fuel.

[0038] The inlet valve 5 intercepts the fuel and is configured to regulate the amount of fuel in transit by directing the first inlet 4 towards the combustion zone 3 . The inlet valve 5 is of a known...

Abstract

The invention describes a method for controlling combustion in a burner (1) comprising a first device (12) for measuring the fuel flow rate (Vg), a second device for measuring the combustion-supporting flow rate (Va) Two means (13), first operator means (14) for controlling the opening of the inlet valve (5) as a function of the quantity of fuel supplied to the burner (1), Function of the amount of oxidant to control the second operator means (15) of the oxidant flow regulator means (8); according to the invention, this device (11) comprises a unit (16) which can be used to control the first operator means (14) and a second operator device (15) as a function of the values ​​measured by the first measuring device (12) and the second measuring device (13).

Description

technical field [0001] The invention relates to a device for controlling the combustion of a burner, a burner comprising the control device and a method for controlling the combustion of a burner. [0002] Preferably, the invention confines to controlling the mixing between the fuel and the oxidant to control the combustion in the burner. [0003] The present invention relates to burners that are used both domestically (eg for heating) and industrially (eg for generating heat in general, for ovens, for heating air, etc.). [0004] More particularly, the invention is used in non-premixed burners, ie, in those burners, the oxidant and fuel are mixed directly at the head of the burner. Background technique [0005] According to the prior art, a burner comprises an inlet duct for a fuel (usually a gaseous fuel) and an inlet duct for a combustor (usually air). These inlet ducts merge in the combustion zone where the burner head is located. In this way, the mixture of oxidant a...
