Valveforce's Boiler House Service Agreement ensures planned regular maintenance and servicing of boiler house equipment. All work is carried out by specialist Valveforce service engineers. An initial audit of the boiler house system is undertaken with the customer prior to commencement of scope of work. The audit typically includes the following: Work on
6 Month visit
Work on major visit
ON / OFF and Modulating Boiler Water Level Controls
Extract the level probes, clean, inspect, check for fatigue and replace using new seal gaskets.
Remove and strip down globe control valve to inspect trim and clean spindle, replace packing once per year. Reassemble body using a new cover gasket, inspect electric actuator motors, potentiometer for wear and travel.
Visually inspect the controller internals for integrity. Check all terminations for tightness and electrical contact. Inspect bases to ensure good electrical contact is made.
Test controls with and empty and de-pressurised boiler then bring up to normal working level with attention to firing the burner and testing cut-out on low water alarm conditions.
Test that the controls are working at normal working pressure.
Carry out a functional test of remote boiler shutdown panel.
Suspended Solids TDS Control systems    
Extract the TDS probes, clean, inspect, check for fatigue and replace using new seal gaskets. Visually check blowdown valve for gland leakage, replace packings once per year. Strip down TDS valve and inspect high pressure drop internals for excessive wear at least once per year.
Take a boiler water sample then compare to TDS controller set point. Recalibrate controller to ensure that only the required amount of boiler water is being discharged.
Calculate and record boiler percentage blowdown rate to assess potential energy losses.
Witness and functionally test the TDS system for correct operation.
Manual and Automatic Bottom Blowdown Control    
Visually inspect the controller internals for integrity. Check all terminations for tightness and electrical contact. Inspect bases to ensure good electrical contact is made.
View timed bottom blowdown settings and ensure optimum times for maximum boiler efficiency. Record settings.
Visually inspect the blowdown valve, actuator and solenoid valve.
Functionally test system to ensure correct operation.
Hotwell and Feedtank Level Controls    
Extract the level probes, clean, inspect, check for fatigue and replace using new seal gaskets.
Remove and strip down globe control valve to inspect trim and clean spindle, replace packing once per year. Reassemble body using a new cover gasket, inspect electric actuator motors, potentiometer for wear and travel.
Visually inspect the controller internals for integrity. Check all terminations for tightness and electrical contact. Inspect bases to ensure good electrical contact is made.
Blowdown Vessel and Heat Recovery Systems    
Check cooling water system for temperature and compare gauge to the vessel. Ensure the TDS heat recovery systems is not blocked and is working as it should be, if possible purge the steam trap.
A service report is provided per visit, noting findings, corrective actions and any recommendations.
