Discussion Overview

The discussion revolves around the design and calculations involved in dense phase pressure conveying systems, particularly in the context of ash handling in thermal power plants. Participants seek to explore technical details, calculations for air balancing, orifice sizing, and the dynamics of material conveying.

Discussion Character

  • Technical explanation
  • Homework-related
  • Exploratory

Main Points Raised

  • One participant seeks detailed information on dense phase pressure conveying systems, indicating a need for specific design considerations.
  • Another participant emphasizes the necessity of more context to provide assistance, suggesting that additional details about the intended application are required.
  • A participant with experience in a thermal power plant mentions familiarity with the system used for evacuating dry ash and expresses a desire for deeper understanding.
  • There is a request for information on design materials, air balancing calculations, and orifice sizing for airflow control, highlighting the complexity of the system's dynamics.
  • Concerns are raised about the observed increase in velocity during material conveying, indicating a need for clarification on this phenomenon.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants have varying levels of knowledge and specific questions regarding the design and calculations of dense phase pressure conveying systems.

Contextual Notes

Participants have not resolved the specific calculations or design considerations, and there are indications of missing assumptions regarding the system's operational parameters.

Hi.

Can anybody help me with detail informations on "dense phase pressure conveying system design"...

Thanks..
 
Engineering news on Phys.org
Not without more info on what you are trying to do, no...
 
Dear Sir,

Myself joined recently in a thermal power plant construction company any and my job profile is in ash handling system; Dense phase pressure conveying system is very familiar to evacuate dry ash handling from ESP. So I need to know more about this conveying system. So please help if possible.

Thanks...
 
Welcome to PF!

Hi prguha! Welcome to PF! :wink:

How much detail do you want?

Have you tried googling "dense phase conveyor" or "dense phase pneumatic conveying"?

You'll get things like http://www.powderandbulk.com/pb_services/ask_joe_archive/what_is_dense_phase_conveying.htm :smile:

Hello Tim;
Already I have collect more or less data about the pneumatic conveying system from Google.. Now I have some idea about the system also. What I need is the design material for this system. How can I calculate the air balancing for material conveying and what will be the orifice sizing calculation for air flow control etc. Even I observed that the velocity at conveying time are increasing with the distance (means material is being convey with some acceleration). I have a big doubt in this matter too...

Thanks for cooperation...
