This video will show you how to overcome an airlock if your system will not dispense fuel after you have had you tank refilled.

What are the implications of using bio-liquids in existing oil storage and supply systems
Findings from the heating oil project have shown that, subject to the use of bio-liquid compatible filters and fire valves, no other modifications are required to the ancillary equipment to facilitate the safe storage and supply f bio-liquid blends. However, it is recommended that all components in contact with oil are proven to be compatible with bio-liquids.
It should be bourne in mind that FAME is hygroscopic. Therefore, it absorbs water and can promote bacterial growth. It also acts as a cleaning agent and will pick up any debris and contaminants contained within an oil storage tank and carry it downstream causing filter blockages.
It is recommended that wherever possible and practicable, new integrally bunded oil storage tanks suitable for bio-liquids are installed as the cleaning effect of the fuel may well find weaknesses in existing tanks which could lead to leaks.
Oil Tank husbandry is essential in maintaining equipment reliability. Prior to storing FAME it is recommended that:
- Tanks should be checked for material compatibility, general condition and all water should be removed; and
- A strict maintenance schedule should be put in place to ensure that the tank remains free of water and bacterial growth does not occur.
Where bacterial growth is identified, specialist help may be required to assist in tackling the problem in emptying the tank, cleaning it and the possible use of biocide additives and filtering. To prevent long term storage stagnation it is recommended that smaller tanks are utilised to increase fuel turnover.
Despite bio-liquids being more viscous, field trials during the winter months have shown that the storage and suppy of the B30K was not prone to premature waxing and is unlikely that there will be a need for supply line insulation or trace heating other than in exposed locations which are susceptible to wind chill.
Attention should be paid to suction line sizing as a correctly sized kerosene suction line may require an increase in diameter for example from 6mm to 8mm or even 10mm due to increased fuel viscosity.
What are the implications of using bio fuel in existing appliances ?
The properties of bio-liquids and bio-liquid blends in comparrision to mineral fuels such as kerosene are different. This is an important factor to bear in mind as this means that to change from 100% mineral fuel (even kerosene or gas oil bio-liquid blend) will require formal conversion and re-comissioning of installations and equipment. Results following fuel analysis identified the viscosity of the bio-liquid to be significantly higher than that of kerosene; literally speaking it is thicker and heavier. The properties of bio-liquids being different to mineral fuels mean it reacts differently to different materials. Traditional oil carrying seal materials,which are commonly encountered in existing mineral fuel installations, were not found to be reliably compatible with bio-liquids.
When considering converting an installation to operate on B30K, its important to ascertain the exact fuel blend and ensure that the supply will be via proven/approved source. Pressure jet burners can be converted with relative ease. Manufacturers have conversions kits available for their equipment to assist with the modification of their existing components to ensure material compatibility. Howevr, in some cases it may be necessary to obtain a bio-liquid compatible burner.
Typically, pressure jet conversion would commonly require at least the replacment of:
- Atomising Nozzles
- Fuel Pumps
- Flexible Oil Lines
- Filters and /or Filter Seals
NOTE : Vapourising burners and appliance installations should not have bio-liquids introduced to them. It has been proven that bio-liquids in kerosene can immediately adversely effect vaporising burner combustion and manifest in the rapid onset of premature carboning in vapourising sleeve burner bases – even within hours. It is recommended that vapourising appliances such as range cookers are converted with appliance manufacturer’s (or appliance manufacturer’s approved) bio-liquid conversion burners.
