Definitions

  • the invention belongs to the field of steam generators.
  • the invention belongs to the field of risk management inherent in the implementation of boilers.
  • the invention belongs to the field of functional safety of boilers.
  • the combustion automaton also comprises safety management means relating to the burner and the combustion.
  • a risk reduction level for a given safety function can be quantified by the Safety Integrity Level (SIL) integrity level, which ranges on a scale of 1 to 4. reliability of the instrumented safety system increases with SIL.
  • SIL Safety Integrity Level
  • the SIL takes into account the probability of occurrence and the risks and severity of their consequences.
  • the figure 2 represents the correspondence table between the level of security integrity SIL and a risk reduction factor RRF ( Risk Reduction Factor in English terminology) equal to the inverse of the average probability of failure at the request PFD ( Probability of Failure on Demand in Anglo-Saxon terminology).
  • RRF Risk Reduction Factor in English terminology
  • the SIL security integrity level of a system depends on the security integrity level of the constituent subsystems.
  • an Instrumented Safety System comprises a sensor subsystem (input interface), a logic subsystem and an actuator subsystem (output interface).
  • the devices composing the subsystems may be arranged in series or in parallel.
  • the figure 4 represents the evolution of the probability of failure at PFD bias as a function of time for two sensors A and B associated with a level SIL 2.
  • the sensor A represented by a solid line curve, can be considered to have a SIL 2 level during a unit of time, for example a year. Beyond that, the average probability of PFD failure is too high. It should therefore be ensured after one year that the sensor A is functioning correctly. After verification, sensor A can be reused for one year without verification.
  • the sensor B represented by a dashed line curve, can be considered to have a SIL 2 level for five time units, for example five years. The operating state of the sensor B is therefore checked only every five years.
  • the invention proposes a safety system for a steam generator that makes it possible to obtain a SIL security integrity level equal to 3. Such a level of security integrity makes it possible to further space out the functional integrity verification tests. security systems. In particular, thanks to the device according to the invention, the safety tests are only to be performed once a year.
  • the invention also relates to a steam generator comprising a combustion automaton, a food pump, a control automaton and a safety device according to the invention.
  • control automaton acts on the combustion automaton and the food pump.
  • the steam generator is a boiler.
  • the invention relates to a safety device intended to be implemented on a steam boiler.
  • a safety device intended to be implemented on a steam boiler.
  • the figure 1 represents a steam boiler 1 in a simplified manner, and the boiler 1 comprises other elements not shown, for example a natural gas supply, a vent, a chimney, conductivity probe, control valve, etc.
  • a heat produced by the burner 11 is transmitted to the feed water contained in the heating element 10.
  • This heat exchange is for example achieved by means of a combustion of a fuel element, such as fuel or water. gas (not shown).
  • the burner 11 is controlled by the combustion automaton 110 which sends a power instruction to manage the amount of steam produced.
  • the pressure switches 40 of excess steam pressure make it possible to detect an abnormal rise in the pressure inside the boiler.
  • the two pressure switches 40 are mounted on the boiler independently. These pressure switches each have a level of SIL safety integrity equal to two, for example a pressure switch from the company GEORGIN (registered trademark), and symbolized graphically by a double border.
  • the very low water level probes 41 control the minimum water level inside the generator.
  • Each of the probes used has a SIL security integrity level equal to three, symbolized graphically by a triple border. It may be, for example, probes from the company GESTRA (registered trademark).
  • the two emergency stops 42 are respectively disposed on one side of the heating body 10 and on an electrical cabinet 14 and each have a safety integrity level SIL equal to three, symbolized graphically by a triple edge. They can be chosen for example from the range of PILZ products (registered trademark).
  • the pressure switches, water level probes and emergency stops form safety contacts connected to the safety PLC 23 via input electrical connections 25.
  • the safety PLC 23 has a level of integrity security SIL equal to four, symbolized graphically by a quadruple border.
  • the relay assembly 24 is connected to the outputs of the safety PLC via electrical output connections 26, and acts directly on the combustion automaton 110 associated with the burner 11, on the feed pump 120 for supplying power. feed water, and on the regulating automaton 13 to stop the boiler in case of emergency.
  • the number of elements making up the relaying assembly is limited compared to existing relaying assemblies in order to limit the probability of failure of a relay element and therefore of the boiler.
  • connection input / electrical output connection is chosen with reference to the safety controller assembly 23 and relaying assembly 24, the information transmitted by the security contacts constituting entries of this set, and the orders sent to the combustion automaton 110, the food pump 120 and the control circuit constituting outputs of said assembly.
  • the electrical connections are symbolized on the figure 1 by dashed lines.
