Page 12: Components
COMPONENTS SIXEN steam generators are equipped with a set of components that can be divided into: – Safety components (safety valves, safety level switches, safety pressure switch). – Indicator components (level indicator, pressure gauge, flame warning light). – Adjustment components (level regulators, pressure switches, pressure transmitters). –... - Page 13 The main components of the safety valve are: Lifting lever Spring Valve body Drain Fluid inlet IMPORTANT Before starting the generator, remove the steel wire that blocks the lever during transport. Make sure that the lifting lever is free to move. In case of conveyed drain, bracket the conveying pipe to compensate the reaction force generated when the fluid is drained.
- Page 14 VALVE MAINTENANCE The valve is a very delicate mechanism, so the system operator must check its efficiency. If necessary, contact a technician authorised by the manufacturer. It is good practice for the safety valves installed to protect the plant: – to be operated (once a week) with system pressurised, by activating the manual lifting lever of the shutter –...

Page 15: Level
Intrinsic safety operation for increasing pressure The figure shows a section of the intrinsic safety bellows for increasing pressure. When pressure increases, the contact lever interrupts the connection between terminals 1 and 2. Should the internal bellows pierce, the pressure will be sent to the external bellows. The external bellows surface is three times higher than the one of the internal bellows. -
Page 16: Installation
With these valves you can periodically test the efficiency of the level control system by performing the following operations. Open the purge valve for a few seconds and close it again. If the water disappears and then quickly returns to the starting point with large swings, it can be assumed that the level works well. Whereas, if the water slowly returns or stops at a different point from the previous, it means that one of the communications is obstructed;... -

Page 24: Loading And Supply Of The Generator/System
LOADING AND SUPPLY OF THE GENERATOR/SYSTEM The steam generator is fed with a multistage centrifugal pump. The water must reach the pump intake with a certain head in order to avoid cavitation. The minimum temperature of the sucked water must be greater than 60°C; this favours the elimination of oxygen which, in any case, must be completely eliminated with suitable chemicals. -
Page 25: Water Characteristics
WATER CHARACTERISTICS The values in the following tables are extracted from tables 5.1 and 5.2 in EN 12953-10 (requirements concerning the quality of water supply and the water in the generator). Even for generators that are not covered by the aforementioned provision it is however necessary to adopt at least the indicated limits and however, to refer to the specialised companies that manage selecting the type of treatment to be carried out on the basis of a thorough analysis of the water available. -

Page 28: Checks After Commissioning
CHECKS AFTER COMMISSIONING With cold start, check that: – the generator is filled with water up to the minimum level – the volume increase due to heating (thermal expansion of the water) does not excessively increase the level making draining necessary at regular intervals to bring the level back to half scale of the glass indicator –... -
