<div>Hi,</div>
<div> </div>
<div>I have a question regarding combustion quality of PG. </div>
<div>When we talk about natural gas, in short 'Methane index/Methane Number' provide combustion quality. For gasolin/petrol it is 'octane rating'. Can we use 'Methane number' as indicator for PG also ??</div>
<div> </div>
<div>Thanks</div>
<div>With Regards,<br>Vikrant Bhalerao<br>Cummins India Ltd.</div>

<br>Please define your version of bio-coal, as it can have differing interpretations. It suggests charcoal, if so, one might expect for you to consider a number of options. Tell us more. because there is a huge gap between raw and "pre-charred" fuel gasification.

<br>Biocoal isNOT charcoal! It contains 80% of the energy in the original wood, but is friable, easily compressed, briquettes or fired as a powder in utility boilers by itself or as an aid to better combustion of powdered coal.<br>

<br>A little clarity is in order. I am a designer for an R&D company that<br>tends to contract to Federal agencies. I have discussions with top level<br>decision makers within the company. I have pointed out the US Army's seven<br>
billion dollar energy acqusition program and have suggested that my<br>employer consider a Power Producing Agreement (PPA) with the Army. I have<br>suggested that Federal lands provide the space for biofuel crops. These<br>
crops would ultimately be converted via pyrolysis to a coal surrogate that<br>can be handled like fossil coal. However, the PPA power would likely have<br>to be distributed in a decentralized, on-site fashion and on a scale much<br>
smaller than the typical gigawatt power plant.<br><br>It's not my interest to employ gasification as the fuel product, but as<br>part of the process to produce a transportable, exportable, friable, solid<br>fuel from the feedstocks. My review of the gasification industry shows<br>
that the technology for producing the "bio-coal" is mature and readily<br>available. However, it doesn't appear there are small scale, power-plants<br>suitable for on-site power production. Any suggestions?<br>
<br>Thanks again, and Bioenergylists is one of the best forums on the web.<br><br><br><br><br>On Wed, Oct 10, 2012 at 12:35 AM, doug.williams<br><<a href="mailto:Doug.Williams@orcon.net.nz">Doug.Williams@orcon.net.nz</a>>wrote:<br>

<br>A little clarity is in order. I am a designer for an R&D company that<br>tends to contract to Federal agencies. I have discussions with top level<br>decision makers within the company. I have pointed out the US Army's seven<br>
billion dollar energy acqusition program and have suggested that my<br>employer consider a Power Producing Agreement (PPA) with the Army. I have<br>suggested that Federal lands provide the space for biofuel crops. These<br>
crops would ultimately be converted via pyrolysis to a coal surrogate that<br>can be handled like fossil coal. However, the PPA power would likely have<br>to be distributed in a decentralized, on-site fashion and on a scale much<br>
smaller than the typical gigawatt power plant.<br><br>It's not my interest to employ gasification as the fuel product, but as<br>part of the process to produce a transportable, exportable, friable, solid<br>fuel from the feedstocks. My review of the gasification industry shows<br>
that the technology for producing the "bio-coal" is mature and readily<br>available. However, it doesn't appear there are small scale, power-plants<br>suitable for on-site power production. Any suggestions?<br>
<br>Thanks again, and Bioenergylists is one of the best forums on the web.<br><br><br><br><br>On Wed, Oct 10, 2012 at 12:35 AM, doug.williams<br><<a href="mailto:Doug.Williams@orcon.net.nz">Doug.Williams@orcon.net.nz</a>>wrote:<br>

Content-Type: text/plain; charset="iso-8859-1"<br><br>Dear Tom<br><br>I would agree with you that a Top Lit Updraft Gasifier, operated in a batch mode would be great for producing "Heating Grade Gas" (HGG), when there was a desire to also produce charcoal. However, if Masi was interested in maximum use of the corncobs for producing HGG, then a "top lit gasifier system" would not appear to be the best approach, because the charcoal left over would be undesirable. Additionally, there is the problem of a "batch operation."<br>
<br>If Masi wanted a gasifier system to produce a woodgas suitable for powering an Internal Combustion engine, I cannot see how the Top Lit Gasifier could possibly produce an Engine Grade Gas. (EGG) I would suggest that it would have excessive tar, that would make it useless for fuelling an IC Engine. Additionally, there is the inherent problem of the batch nature of the TLUD gasifier.<br>
<br>As I see it:<br>1: The TLUD gasifier is great for use with a close coupled burner system, where there is a wish to produce a residual charcoal, and where batch operation is acceptable.<br>2: A TLUD gasifier is not appropriate for producing Engine Grade Gas, because of an unacceptably high tar content.<br>
3: A TLUD gasifier is not appropriate unless it is desired to produce a charcoal by-product.<br><br>I might be missing something, but do you know of any way that a TLUD can produce engine Grade Gas?<br><br>Best wishes,<br>
