GA DRAWING COMMENTS (16 sq.m and 20 sq.m SPDU):

Spiral Baffle Pitch:

I approve the spiral baffle pitch shown on these drawings. The assumption that double the flow area is required is exactly how I would have approached this.

Entrainment Separator Rotation Direction:

This is my final chance to raise some questions/doubts on the entrainment separator design regarding the direction of rotation of the entrainment separator blades. Bear in mind that these I do not want these discussions to result in a long drawn out design phase for the rotors of these units. 

Basically the units at GVT are performing satisfactorily regarding color of the oil coming off of these units. But the question continues to come to me: “Would these units put off better product if the rotors (ES Vanes) were spinning in the opposite direction.” While sitting in the Patil living room in your house on a hill in beautiful Nasik we discussed the pros and cons of both rotational directions and even today we had these discussions with Subu and Sara. And I have a feeling that I will continue to have these discussions if we someday do not decide this question in the field. So my question is this:

“Can the hinged wiper supports be designed in such a manner that the blades can be switched in the field to test this theory at a later date.” This switching would most likely take some small welding to reattach the wiper pins and that would be acceptable.

I look forward to your thoughts on this matter so that we can quickly decide which way to go. As stated above, I do not want this to turn into a long drawn out negotiation that will result in a project delay.

Thanks.
