Difference Between ASME Power Boiler and Heating Boiler

When you create power you go with section 1 Power Boiler

If you just talking of "process heat" you use section 2

As per description there will be a difference in the pressure in the system.

The cut off is 160 psi.

Thanks for the reply.Your theory is noted. Based on that theory, I need a small clarification on my following query,

A boiler to be designed with an operating pressure 200 Psi (g) and operating temperature not exceeding 213.8 Degree Fahrenheit. In this case, ASME B&PV Section-I or Section 2 is applicable?

Whats the purpose of said boiler?

Thanks for the reply.The situation as follows,

The boiler is supposed to be erected in between a power plant and a process plant. There will be two branches from the main steam header. One branch will go to process plant to supply process heat and another branch will go to power plant to supply steam for power generation.

Let me know , if you need more info.

I believe you just answered your own question.

Put it that way. A rope has to hold a 5 ton load and a 3 ton load.

Will you can go with higher or lower specs for the rope.

What do you choose?

But there might be something in the standard pertaining to your situation.

Standard? Which standard?

Code then if you wish.

ASME is a standards organisation.

ASME is the abbreviated form of American Society of Mechanical Engineers.

ASME May be or may not be a 'standard' or 'sub standard' organisation. I don't know much about it's internal working system.So I am not eligible to comment on this subject.

However my query was based on ASME B&PV Section-I and ASME B&PV Section-IV (According to you Section-2)

So, these two documents (ie, American Society of Mechanical Engineers Boiler and Pressure Vessel Section-One and American Society of Mechanical Engineers Boiler and Pressure Vessel Section-Four a.k.a Section-Two) are considered as standard or Code or Recommended practice or Something else as per ASME (American Society of Mechanical Engineers)?

I see further down that it would be necessary for you to delve deep into the matter.

Process heat generated when mainly HEAT is required where as in a power generation process the heat is a byproduct and the POWER is what is needed.

Why on Earth are you looking into the code when you don't even quite know what a boiler does?

Sorry to be so frank but it is a curious mind of mine.

Thank you very much for the link and explanation. No problem for your query.But I don't know, how to give a specific answer to your query.Because your query has no connection at all to my original query (ie, off topic!)!

When the Boiler Inspector comes along to certify your boiler, your understanding of the Code and your design criteria will be more acceptable than the views of any members of any forum -with all due respect to my forum colleagues.

The ASME Code is fairly clear here though;

ASME Section 1 Power Boilers Section-I power boilers process boilers and high pressure boilers

"boilers in which steam or other vapor is generated at a pressures exceeding 15 psig"

Thanks for the reply and your theory also noted. All theories are good and gave me a fair understanding of the ASME B&PV Section-I preamble.

However, I disagree with the terminology 'Boiler Inspector'. As per ASME B&PV Code, the inspector who is authorised to inspect the boiler or pressure vessel is known as 'AI or Authorised Inspector' instead of 'Boiler Inspector'.

You should be word-crunching in the code! What is the difference in how you name the inspector please?

This will help you to understand about ,

inspector http://en.wikipedia.org/wiki/Inspector

Code http://en.wikipedia.org/wiki/Code

Standard http://en.wikipedia.org/wiki/Standard

Recommended Practice http://en.wikipedia.org/wiki/Standards_And_Recommended_Practices

Even you don't know the difference between Code, Standard and Recommended practice! Then why are you asking about Inspector?

Feel free to ask for more info.

There is those that can reurgitate definitions and dwelve on words and phrases and then there is engineers that understand associations and facts.

You clearly showed that you understand words and phrases. Now you just have to learn to put it in prospective.

Good luck!

<...didn't get enough time...>

Time is infinite, though. Why not use the time spent waiting for replies on CR4 to actually complete reading the documents?

Thanks for the participation.

I think, it will be very difficult for a dumb person like me to mug up the entire code book with in couple of days. I have heard that CR4 is filled with highly experienced intellectuals of current world. So, I think it is better to get the advice from experienced CR4 intellectuals before going to read the code book.

Heating boilers produce mainly saturated steam which is mainly used in factories for processing heating purposes.

Thanks for the valuable input. That means heating boilers does not have a super heater? To be frank, I don't know anything about heating boilers.I read from books about boilers with water wall panel , economiser, steam drum, water drum, main header and a super heater section. If you have any experience or knowledge in heating boilers, pls share.If possible please give the main difference between power boiler and heating boiler.Any technical presentation on heating boilers and power boiler are also welcome.

I found some information and I would like to share here.Thanks to babasiga for his/her precise info. on the subject.
