Waste Vegetable Oil / Re: My New WVO Processor
« on: October 19, 2011, 11:58:08 PM »
veggie,

I noticed you've got a pressure relief valve in there where I see a lot of systems just using a ball valve to get about 90 PSI out of their pumps.  I've been warned against our cheap friend that is on most every water heater.  What are you using?  Do you have any other suggestions.  

Casey

Casey,
The R/V is a spring loaded, adjustable brass unit with 1/2" NPT connections.
Cost me approx. $20 at a water systems supply store (Water well pumps, pressure tanks, etc...)

It's there against accidental valve closure which might blow a fitting or hurt the centrifuge.
The R/V has a dial adjustment which is set at 90PSI (The upper recommended limit for the centrifuge).

cheers,
veggie

Nice move Casey,

When you see 1/3 of a cubie as a creamy white liquid.....RUN !
That's saturated fats. Bad for WVO us burners and usually unwanted by bioiesel refiners.

The oil I get stays in the restaurant frier for approx. 1 week.
It is darker when I pick it up compared to when it's finished
processing, but I have seen darker oils from some of the other suppliers I worked with.

I really enjoyed watching this video and several others on your site. I am amazed how pure the processed oil looks as it came out. Did you start with dirty waste motor oil?

Yes. I take the collected oil and settle it for a week. Then pour it through a strainer into the processor.
I think the key to this system is to keep the batches small and try to get as many passes through the centrifuge as possible in a 1 hour period.
( I say 1 hour because that's what I targeted as a processing time )
That's why I reduced my tank from a 45 gal. drum to a 9 gal. (30 liter) vessel.

thanks for the update

question
Do you know how much energy is consumed during processing?  
Deeiche

Yes...
Heater = 500 watts
Pump = 230 watts
Fan = 75 watts
============
Total = 805 watts

Warm up time is 1/2hr = 500 watts X 1/2 hr = .25 kw/hr
Process time is 1 hour = 805 watts or .8kw/hr

Total elec. energy used is = 1.05 kw/hr

In my area I pay 8.5 cents per kw/hr so total processing cost is 8.9 cents.

Now, if I had to process off grid using the listeroid, I would burn approx. 1 liter of fuel to do this job.
So, for every 20 liters of free WVO that I process, 1 liter would be used, netting 19 liters of product.

cheers,
veggie

Hi All,

I finally found an LD1 and joined the ragtag fugitive gang of Lister owners !  ;D

Can anyone help me determine the year that my engine was made?
Serial number is: 643LR118

Hi Todd,

The Changfa 1115 (12kw) does not have any low level thumps because it has internal counterbalance shafts to negate a thump.
It's actually a very smooth engine. Therefore tires won't make much difference.
What the Changfa's do have is a very loud ignition knock and lots of internal gear clatter because of the straight cut gear teeth driving the counterbalance shafts.
Here's a few of the things that help to tame a Changfa....

- A good (low back pressure) exhaust muffler
- An inlet air muffler (not critical but you will get a pop...pop...pop...without it)
- An enclosure (small box or full shed) lined with acoustical foam. Be careful to keep adequate air flow for cooling.
- RPM....The noise drops substantially below 1800 rpm (if you don't need the full HP output of the engine).

I got the best results when the engine was slowed down and an exhaust muffler added.
Here's a link to discussion and video of my Slow Speed Changfa project on the MicrCogen forum.
http://www.microcogen.info/index.php?topic=477.0

If it's any consolation, I've heard they quite down somewhat after about 1000 hrs. of running  :) so you can look forward to that.
(I don't have anywhere near that much time on my Changfa yet.)

***GM90 HEAD GASKETS***

Hi everyone,

I have been working with John to produce a gasket for us GM90 users.
I sent a GM90 head gasket to John at "Gaskets to Go" and a gasket is now available for the 6hp and 8hp GM90 models.

John is making the gasket available via an Ebay page here.....

I have tried the gasket myself and I am happy with the results,
