Issues we have found with burning oils.

Most of the time your oil will come from the same source, so your heater will sit on the same delay and pump times all the time and nothing changes, however there are times when your going to receive oil from other suppliers who you don't know the purity of the oil as we did last week. The first 6, 20 litre containers where hydraulic oil excellent stuff burnt very clean, with no real ash build up in the burning pot. We had to change our settings from car engine oil we were burning from 6 second delay, to 13 seconds delay for the hydraulic oil.

However went to the next container started to pour it into the heater container, and saw it was very thin so didn't go any further. Lite the heater with that oil I poured in, and the water temperature shot up from 64-85c very quickly. This heater had been running all day clean as it should on hydraulic oil, then noticed every time the pump pumped smoke would show out the flue, not alot but enough, so I increased the delay time from 6 seconds eventually to 12 seconds no change with the puffs of smoke although the water temperature did decrease, it wasn't so much the temperature of the water but the rate of increase which said to me there's either alot of either petrol or diesel in the oil, and I think it was the latter as petrol won't create smoke. By this time the day had warmed up so I turned it off. So to get around this I poured that oil mix into the waste oil drum where the diesel will be mixed at a lesser consistency than it was in the 20 litre container, now the next 20 litre container is the same but I could smell petrol in this one, so we won't be using it as heating oil but for starting the heater from cold only. For your own safety never start a hot heater with petrol or even diesel, never! You'll get a meter away from the heater before it goes bang. And it isn't a small bang either, it's not so much the bang it's the skin burnt off your legs, the flue changing to a rocket, and the black sooty ash everywhere, it's a big clean up job.

My heater started to play up last couple of days, oil wasn't flowing as it normally does, and wanted to go out soon after lighting it, so presumed it had a blockage, so I popped the compressor gun down the inlet tube while the pump was going that seemed to clear it, however found out later not so, so removed the filter and cleaned it with petrol a messy job, blew out the tubes and put it back together. I ran the oil for a while into a different pot in the heater once we have 1/2 a litre into the pot removed it and poured it back into the drum, lite the fire, and away she went and has been going all afternoon which is great. So yeah you'll get blockages from time to time especially when getting near the bottom of the drum. Or you get a delivery of crap oil.

So if your heater smokes it's simply because there's too much oil going into the pot, by increasing the delay time on the wo controller you will clean that up and if you still have a slight smoke increase the fans speed to clear that up.

With it comes to the new blue flame heaters, the fan needs to be powerful, and the issue with smoke doesn't come into it. 

So much for renewable energy, which obviously can't be achieved without burning coal or gas.

We have been mislead!!! We need to learn how to burn this stuff cleaner then.

Genesis Energy to phase out Huntly coal use

2:18 pm on 14 February 2018

Genesis Energy has pledged to stop using coal to generate electricity except in exceptional circumstances by 2025.

Then it goes to say Huntly power station looking to going until 2022, that covers their arse.

Sitting under the umbrella of hydro but as water is drying up reverted back to coal.

New Zealand has 17 wind farms operating. These wind farms currently have a combined installed capacity of 690 megawatts. They supply around 6% of New Zealand’s annual electricity generation, which is about the same amount of electricity as 300,000 kiwi homes use in a year.
There is currently approximately 2,500 MW of wind generation consented in New Zealand and developers are exploring sites throughout New Zealand for new wind farms.
Developers generally progress from holding a consent to build once they are satisfied that market conditions will provide a commercial return. It is not expected that all consented wind generation will be constructed.
