Abstract

The invention concerns a process and a system for controlling the correct operation of pressure equipment, comprising a generator (1) of a heated fluid, a burner (14), safety devices comprising at least a first pressure sensor (2) and at least a first temperature sensor (3) for said heated fluid adapted to detect working parameters (p, T), an electrical panel (4) comprising a device for management, control and signalling of any faults, where said process comprises the steps of: providing a second pressure sensor (5), a second (6) and a third (7) heated fluid temperature sensor, a fourth (8) and a fifth (9) flue gas temperature sensor; providing a logic control device (10) connected to said second pressure sensor (5), said second (6) and a third (7) heated fluid temperature sensor, said fourth (8) and a fifth (9) flue gas temperature sensor; providing a plurality of switching devices that act directly to shut down the burner (14); providing a plurality of interface devices (15) that allow interaction with said logic control device (10); providing a measuring device (16) of the operating time parameter (t) of said generator (1); switching off said burner (14) and generating an alarm signal if the preset limit value exceeds even only one of the working parameters or upon reaching the zero value of said operating time parameter (t).
