Likewise draining and drying the boiler (emphasis on drying) is time consuming and leaves the boiler space full of air which will inevitably mix with the water introduced to the boiler for startup.

The above are the major water and steam circuit items in a boiler and are collectively called the ‘pressure parts’. This post is part of the series: Working Of A Power Plant Boiler. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat.
Choosing the best lay-up method for your boiler is not always so apparent and it sometimes makes sense for you to consult with an experienced water treatment service provider. A Dry boiler lay-up protocol should be used if boiler will be shut down for an extended period or when there will be no foreseeable urgency to restart the boiler.
A fourth boiler was needed at the plant. Two of the three original gas/resid-fired packaged boilers, each rated 40,000 lb/hr of 325-psig saturated steam when new 30 years ago, barely cover the typical peak winter steam requirement (process and heating) of 75,000 lb/hr. Steam heats the oil used for frying chips in a shell-and-tube heat exchanger
The preferred condition for boiler lay-up is dry; removing the water from the system is the best way to eliminate off-line corrosion. Every effort should be made to use the residual heat in the plant to assist the drying-out process. As boiler plant is brought off-load, it is normal practice to blow empty the boiler and associated circuits
The plant layout shall be arranged to: 1. maximize safety; 2. prevent spread fire 3. Facilitate easy operation and maintenance 4. Consider future expansion 5. Economize project Blocking The plant site shall be blocked in consideration of hazards attendant to plant operation in the area. All blocked areas shall be formed as square as possible by
Industrial Plant Layout: Meaning, Definition, Need and Importance! Meaning: Plant layout is the most effective physical arrangement, either existing or in plans of industrial facilities i.e. arrangement of machines, processing equipment and service departments to achieve greatest co-ordination and efficiency of 4 M’s (Men, Materials, Machines and Methods) in a plant.
The exact steps involved in both of these lay up procedures differ between boiler sizes and models, but in general these are the appropriate steps technicians should follow when shutting down their boiler. If your company does not have an experienced operator capable of performing a boiler lay up, contact Powerhouse today. Step 1 - Drain Your
The steps of preparing a boiler for wet lay-up are essentially the same for dry lay-up. The exception is when a boiler is closed and prepared to be filled with water and water treatment chemicals. Perform dry lay-up steps 1-6 (except do not swab the fireside with mineral oil) and then follow with step 7 below.
