Presented at ICALEO 2011

Fusing of glass tubes for solar thermal collectors is dominated by the flame based heating and melting technology. The low energy transfer efficiency of the flame in conjunction with long process times, leads to massive gas consumption. Consequently, the use of high amount of energy for fusing raises the interest to substitute this process by a more efficient one...
