Fuel conversion.Β Many different parameters was important for fuel conversion. The influence of fuel reactor temperature and specific fuel reactor inventory is shown in figure 6. Tests were performed using specific solids inventories between 619-1650 kg/MW. For the case with 1650 kg/MWth the fuel flow was not high enough to fluidize the bed and therefor nitrogen was added to the fuel to increase gas velocity. This of course, has the effect of diluting the methane stream, which could affect the reactivity. From the figure it is evident that the gas yield varied between 60-85%. The gas yield increased as a function of solids inventory and temperature. Another important parameter for fuel conversion was the total inventory of particles. Unfortunately the total inventory was impossible to keep constant due to the high elutriation of particles. The total inventory also affects the circulation of particles which is an important parameter for fuel conversion. In the current experiments the air flow was varied between 160-180 L/min, but no observable effect on conversion was seen.

Oxygen itself gets a negative oxygen demand since it can be used to burn the other gases. The fuel conversion is an equivalent parameter to the methane conversion in other units. 𝐢𝐻4 + 𝟐 𝑂2 πŸ‘ͺ 𝐢𝑂2 + 2 𝐻2οΏ½οΏ½ 𝐢𝑂 + 𝟎. πŸ“ 𝑂2 πŸ‘ͺ 𝐢𝑂2 𝐻2 + 𝟎. πŸ“ 𝑂2 πŸ‘ͺ 𝐻2𝑂 𝐢2𝐻6 + πŸ‘. πŸ“ 𝑂2 πŸ‘ͺ 2 𝐢𝑂2 + 3 𝐻2𝑂 𝐢3𝐻8 + πŸ“ 𝑂2 πŸ‘ͺ 3 𝐢𝑂2 + 4 𝐻2𝑂 Another important value is the global air-to-fuel ratio (Lambda). The available oxygen in the air reac- tor is set in relation to the needed oxygen for combustion of the corresponding amount of natural gas. The total available oxygen (air reactor feed) is lowered by the oxygen that is needed for combus- tion of added propane to the air reactor. πœ† = (𝑛̇𝑂2 )π‘Žπ‘–π‘Ÿ π‘Ÿπ‘’π‘Žπ‘π‘‘π‘œπ‘Ÿ 𝑓𝑒𝑒𝑑 βˆ’ (𝑛̇𝑂2 )π‘Žπ‘–π‘Ÿ π‘Ÿπ‘’π‘Žπ‘π‘‘π‘œπ‘Ÿ π‘π‘œπ‘šπ‘π‘’π‘ π‘‘π‘–π‘œπ‘› (𝑛̇𝑂2 )π‘›π‘Žπ‘‘π‘’π‘Ÿπ‘Žπ‘™ π‘”π‘Žπ‘  π‘‘π‘’π‘šπ‘Žπ‘›π‘‘

  • Casual Conversion A casual Employee, who has been engaged by the Employer on a regular and systematic basis for a period in excess of six-weeks, thereafter, will have their contract of employment converted to permanent employment unless otherwise agreed in writing between the parties. Regular and systematic shall be defined as an average of 4 days or more, per week, over 6 weeks. Eligible current employees will be transitioned to full time no later than 6 weeks from the date of approval of this agreement.
