<p>A heating plant with radiant tubes comprising a burner of a gas - coitiburent air mixture suitable for generating high temperature combustion products which are introduced in a closed circuit with radiant tubes where they heat a carrier fluid circulated in depression by the action of a fan arranged upstream of the burner. There are provided regulation means comprising an regulation valve of the gas rate, whose modulation is directly controlled by at least one pressure value, detected into the combustion chamber, which at the same time determines the forced suction of the comburent air rate.</p> |
