— gas fuel based on MAF — the so-called. methylacetylene-allene fraction (plus about 25% propane for stabilization). In terms of combustion characteristics, it is similar to acetylene (see the relevant paragraph), it gives a slightly lower flame temperature (from 2900 °C), but has a higher calorific value. At the same time, MAF costs 2-3 times cheaper, compresses better and does not require fillers for storage in cylinders, due to which almost four times more MAF can fit into one standard cylinder than acetylene — 21 kg versus 5.5 kg, with the same total weight containers.
