Problems solved by technology

For example, it may be necessary to change the pipe circuit by introducing bends or height differences, which determine undesired, unexpected load losses
[0025] Known equipment does not allow modulation of carrier fluid flow to compensate for differences in design and actual operating conditions found in routine equipment operation
In particular, it is not possible to use fans in a universal manner, and as a result, current devices often do not work under ideal conditions and with maximum efficiency

Embodiment approach

[0069] According to one embodiment, the regulating device comprises a flow regulating device of the carrier fluid 5 .

[0070] According to the embodiment of the present invention described in FIG. 4 a , such means for adjusting the flow rate of the carrier fluid 5 may include means for adjusting the speed of the fan 7 , such as converters 11 or other types of actuators.

[0071] According to the embodiment of the invention described in Figures 4b, 4c, such a flow regulating device for the carrier fluid 5 may or may not include one of the inlets of the flue gas discharge chimney 13 and / or the suction duct of the combustion air A Or more adjustable doors 12,120.

[0072] In particular, each of said doors may be arranged individually or in combination with other doors and in combination with or independently of predetermined fan speed actuators.

[0073] From an operational point of view, this means of regulating the flow of the carrier fluid 5 - whatever its specific embodimen...

Abstract

A heating apparatus with radiant tubes includes a burner of a gas-combustion air mixture, the burner being adapted to produce high temperature combustion products. These combustion products are introduced into a closed circuit with radiant tubes. In a closed circuit, these combustion products heat a carrier fluid, which is circulated at low pressure under the action of a fan arranged upstream of the burner. The equipment is provided with regulating means, including a regulating valve for gas flow. The regulation of the regulating valve is directly controlled by at least one pressure value detected in the combustion chamber which at the same time determines the forced intake of the combustion air flow.

Description

technical field [0001] The invention relates to a heating device with a radiant tube. [0002] In more detail, this device can be conveniently used for heating any type of area, such as residential and industrial buildings, especially large buildings such as warehouses, factories, theaters, cinemas, supermarkets, greenhouses, swimming pools, etc. Background technique [0003] Such equipment is provided with burners for producing high temperature combustion products, which are hereinafter referred to as flue gases. The flue gas circulates in a closed circuit. The circuit consists of radiant tubes capable of heating the above-mentioned areas by radiation. [0004] Due to their shape and modularity, radiant tubes are also called radiant belts in the technical terminology of the art. The radiant tubes consist, for example, of annealed or aluminized steel pipes and are arranged slightly below the ceiling of the building to be heated, preferably using thermal radiation in the i...
