Welcome Center / Re: oil and water

Hi rich, I have 3000litres of this oil. Its been standing for 2 weeks or so and there is zero water in the bottom. Shiny black used oil.
There is no air to bubble thro the preheat tank it is black and only foames if heated above 100 C  ie boiling point of water.
Does the term 'hydroscopic' come in to this.

At the moment it is running fine at 90 C on half gas oil and half this suspect oil but this does spoil the economics of the job

Might be an interesting angle for US.
My understanding is that the UK regulator (Env. Agency boooo) lost a case in the high court which ruled that use of the oil in question to HEAT gave it a purpose and it was no longer a Waste product

Hi, first post an fron UK and have a 55kw Giersch preheat pressure system
Problem is have the first batch of oil that has been delivered from a waste oil pick up tanker.
After a few days of this oil am having cut out problems

No water  drains off from bottom of the tank but foamy bobbles with 'milky' appearance if I heat to 110c to try and get it to ignite. Lower temps not lighting and foam overflows and shuts off system

Ha, have it running on half diesel and half oil at 90C  Next is to reduce tractor diesel %
