RE:Computer modeling The durability of the torches is well known and only a small portion of the torch would be in the furnace. Any auxiliary or supporting equipment would be proven technology (gas supply for example). Peter has stated the life of the torch is similar to the oil burners that they will be replacing, 20-25 years. The properties of the metal used to manufacturer the torches are known and selected for durability. There are consumables that requires maintainance and replacement every 6 months or so that the 5% $$$ yearly maintenance contract would cover, buyers are aware of this also as it is part of the negotiations.
Finally, these will come with significant warranties without a doubt. I highly doubt reliability will be a major concern.

It's led me to wonder what computer modeling can and potentially can't tell a customer about the effects of new equipment on an industrial process. We know Clients A and B were happy with the results of the modeling. It's been stated the torches have no effect on the quality of the pellets and there is operational cost reductions. But my question is can it tell anything about the durability of the torches under real life operating conditions? Is the reason Client B requested a quote for such a small number of torches is they want to test durability for a certain amount of time? Perhaps someone on the board has experience with computer modeling.
