Thank you very much for the information. I have been checking your links, and they are so helpful for me. I´m trying to find throttling calorimeters manufacturers, but I don´t find so much. Please, could you tell me some manufacturers??? I would be so pleasant. thank you very much again;

Hi everybody; Please, could anybody tell me a device to measure the quality of the vapour? Reading literature, I found a device that throttles a portion of mass flow. The philosophy consists in the measure of the throttled mass flow (isoentalphic throttling)in order to know the quality of the...

Hi everybody; I´m project engineer and I´m entirely involved in a heat recovery project. I´m defining a condenser, and I would like to know a software to simulate its performance in order to define it. So please, could anybody tell me a program, software...?? My intention is to use a plate heat...

OK MJCronin You are right. I didn´t know the difference between both concepts. I am interested in PROCESS ENGINEERING. So, could you tell me a link, guide, manual or something useful related to the PROCESS ENGINEERING??? Thank you so much

Hi everybody; Could anybody tell me a link, guide, manual or something useful related to the piping design in Organic Rankine cycles? Piping design in conventional Rankine cycles could be useful as well. Thanks

Hi everybody!!! I´m project engineer and I´m working in a Rankine cycle project. We are in the state of the project related to the pump definition. My question is, could anybody tell me a list of the best centrifugal pumps manufacturers? Thank you very much

I have been reading literature about boilers and after talking to manufacturers, I assume that that in plate exchangers cross of temperatures are allowed, that means that we are able to reach a higher temperature, in the outlet of the working fluid, than in the outlet of the cooling water...

Hi Rmw. Can you tell me the definition of pitch point? why did you recommend amot valves? Please explain me why we must not design the heat exchanger for the maximum condition, can you explain me that? Thank you for all

Hi everybody. I´m project engineer working in a new project. Our intention is to recover thermal power from the cooling circuit of an engine. We are going to set up a 3 ways valve in the outlet of the engine (instead of termostates) to maintain 90 ºC in the heat exchangers inlet. The temperature...

Hi everybody again!! thanks for all your answers, they have been really useful for me. We are still deciding the expander, this state of the project is lengthening too much. My question is; Does anybody know the operating mode of the vane compressors? Could you tell me a useful web side for that...

First of all thanks for your reply bigInch. Ok, but I think you didn´t understand what I´m looking for, that is; I´m designing a Rankine Cycle. sometimes I have less thermal power available, so we have to pump less mass flow to reach the same thermodynamic state. The problem is that we have to...

Hi everybody. I´m project engineer from Spain. I´m workig in a rankine cycle project and we are in the state of the project related to the pipes design. We have some doubts: If we reduce the mass flow, what happens with the pressure? (I think it drops, but I don´t know why). our intention is to...

Hi everybody! I´m project engineer from Spain. I´m working in a new Rankine cycle project and I´m looking for a heat exchanger (condenser). The conditions are different depending on the season, that is; Summer conditions: P= 2 bar, Temperature from 50ºC (inlet) to 33ºC (outlet) Winter...

First of all, thank you very much for all.Dcasto , there are no movies in the links or I didn´t find them, so I still don´t know the concept of bypassing. The rest of information helped me a lot, so, thanks again. What about air motors? how do they operate? and what about their efficiency? could...

Thanks for your replay dcasto. So the principal function of the oil is acting like a seal, but it works also as a refrigerant I suppose. I read some information about screw compressors and "dry ones" exist, that is; without oil injection, do you know this technology? I don´t understand the...

Thank for your prompt replay dcasto. I have some questions, what "high bypass rate" means? I don´t understood what do you want to say. The outlet pressures are 1 bar or 2 bar depending if we are in winter or in summer conditions. We are talking about a global efficiency of 11 percent in winter...

Hi everybody! I´m project engineer. We are working in a new ORC (Organic RAnkine Cycle) project and our porpouse is to recover thermal power from a low temperature source. The inlet conditios in the expander (is not defined yet) are: T=82ºC and P=8,3 bar. The oulet conditions are different...
