Preparing your tanks for winter

Here are two recent headline stories that will likely affect generator fuel and its usage in the coming winter:

Winter 2014 set to be ‘coldest for century’ Britain faces ARCTIC FREEZE in just weeks

Heavy and persistent snow, freezing gales and sub-zero temperatures threaten to grind the country to a standstill for up to FIVE MONTHS, horrified long-range weather forecasters have warned. The impending bout of extreme weather will come as a shock and forecasters have warned Britons should not to be lulled into a false sense of security by the recent mild conditions. January is currently showing signs of temperatures hitting “record-breaking” lows meaning parts of the country could see the mercury plunge to -27C (-17F).

National Grid warns of lower winter power capacity

National Grid has warned that its capacity to supply electricity this winter will be at a seven-year low due to generator closures and breakdowns. Spare electricity capacity, which ran at about 5% over the winter months last year, would be nearer 4% this year, National Grid said. Three years ago the margin was 17%.

Fuel tanks and more specifically the fuel they hold, can be affected by cold temperatures. As the temperature drops, the fuel “waxes”. The colder it gets, the thicker and more difficult the oil will be to pump or use. Generators themselves will typically be in a pre-heated room, but if you need fuel from an external bulk tank, you may not be able to get it!

More things to know:

  • 1. Have all bulk tanks checked for water & sludge in the bottom, immediately remove anything that is found other than good fuel.
  • 2. Take a fuel sample from the top & bottom of each tank. The samples will be lab analysed and we will offer a report on each tanks fuel condition. Particular attention will be paid to any suspended water in the fuel.
  • 3. If necessary, polish or filter the fuel to get rid of any suspended water or contaminants.
  • 4. Treat the tank with a winter fuel additive, the additive will need to be fully circulated in the tank.

Additional Facts:

Diesel Waxing

Diesel fuel is prone to waxing or gelling in cold weather; both are terms for the solidification of diesel oil into a partially crystalline state. Below the Cloud Point the fuel begins to develop solid wax particles giving it a cloudy appearance. The presence of solidified waxes thickens the oil and clogs fuel filters and injectors in engines. The crystals build up in the fuel line (especially in fuel filters) until the engine is starved of fuel, causing it to stop running.

Winter Fuel Additive

FSS offer a hydrocarbon based liquid which is added in advance to diesel fuels during the winter months at dosage rates as low as 1:1000.

We do not prevent the formation of wax crystals, and the cloud point of fuel is not lowered. The additive actually encourages the initial formation of wax crystals as the cloud point temperature is reached, controlling their formation so that the resultant crystals are much smaller in size than those in untreated fuel. Other components inhibit the further growth of wax crystals, which remain as long needle-like crystals which can pass through fuel filters. The viscosity of treated fuel does not increase substantially, unlike untreated fuel, another factor leading to fuel starvation at low temperature.

Dispersants maintain the fine wax crystals in suspension throughout the fuel, preventing separation and settling, which can block outflow pipes and filters. Treated fuel will continue to flow through fuel lines and filters down to temperatures below -22°C

NOTE: Additives will not affect fuel that has already started to wax. They MUST be added before temperatures drop below 2°C
