boiler flash up procedure
TOPICS TO BE COVERED
Boiler flashing up procedure
Procedure to commission new boilers
Procedure of raising steam from cold
Soot Blowing Procedure
Actions to be taken during Fire and explosion in boilers
Boiler emergency conditions and actions to be taken
OBJECTIVE
To contribute for the first lecturer’s assessment (LA) for the engineering knowledge steam subject.
To make sure that the course is more interesting and not only one sided.
To ensure everybody understands the topic better as it is presented as per students understanding.
To make sure proper teamwork is practiced by everybody regardless of motor or steam ships.
INTRODUCTION
Hence the job has been divided into this 3 main topics as per our team leaders instruction.
Research was carried out and the product of the research is this presentation.
We hope that everybody will understand and gain a lot from this presentation
INTERNAL INSPECTIONS
All tubes – proved clear from oil, tools etc
Apertures in drum ends to water gauges – no blockage
Internal surfaces – free from scale and oil, includes oil from tube expanders
Internal fittings – fully secured such as perforated plates, feed pipes, internal steam pipes and baffles
Header hand hole plugs and manhole doors – replaced
EXTERNAL INSPECTION
Refractory – good condition especially protecting drum surfaces
All valves, safety valves and cocks – good operable condition and shut
Manhole and hand hole door joints – good condition and tight
Superheat control valves – correctly set, all initial flow must through superheaters
Gas passage - clear
FLASH UP BOILER PROCEDURE
• Lined up blow down valves.
• Run up Main D/Alt. paralled with running T/Alt.
• Ensure Steam Drum Vent Valves, Superheater Vent Valves, Hot Start Valve Manual
