<div><br></div><div> The problem with IIsc desig design has some gas recirculation un like many other incluing GEK , thus more flexible. You need to increase the air inlet temperatures such one well done in GEK , steam quenching can hlep solve your problems .Some opeartional resarch , optimization as recently done by the new generation of gasifers such as Two stage gasification modifications by dutch univeristy Mechanical engineering departments , can be also used in solving tar lignin condensation of your systems </div>
<div><br></div><div> Increasing temperatures is one way , where lignin need to be cracked. Free radical help fragmented condensed condensation and tar problems , depending on the temperature.</div><div> Tom Reed is in favour of several chemical uses for this tar as product , as this can be very easy seperated </div>
<div><br></div><div>There are many ways to solve ,wish your team a good undestanding of problems , process, controls and optimization problemas and good solutions</div><div><br></div><div>Thanking you<br><br><br>Yours truly</div>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">I was working on the biomass pellet trial on one of the wood chip gasifier (Gasifier design is IISc India design- Open top downndraft). I found that gasifier was able to make good quality gas when switched from wood chips to these biomass pellets. However, two major problems I came across are TAR and Clinkers. Clinkers are primarily due to the temperature in the reactor bed which is exceeding probably ash fusion temperatures for the biomass pellets I used. I want to know from you the ways to control this reactor bed temperature inside gasifier, such that I can avoid clinker formation and also reduce the temperature<u></u><u></u></span></p>
