Although acetylene generators for used in welding and cutting are "Water to Carbide", "Carbide to Water", and Dipping" type, almost generators have been designed from the empirical data. We have introduced from many actual working shops that the requred pressure of accetylene at nozzle is 0.03〜0.1kg per cm^2 for manual welding (or cutting) and 0.3〜0.5kg per cm^2 for automatic. When we design the large capacity automatic acetylene generators (1) Average acetylene yield (2) Acetylene yielding rate (3) Water temperature (4) Quantities of carbide residue are necessary basic data. However, from the theoritical standpoint, the relationship between acetylene yielding rate and water temperature is most important. Authors settled the foundamental data for construction the acetylene generators by measuring the acetylene yielding rate and some. For the acetylene yielding rate measurement, for example, the second class carbide (JIS) 5kg. 7cm cubic lumps dipped at 20 ℃ water temp., we can yield 4m3 acetylene per hr., and at 30℃, 5m^3 per hr. We concluded also that 35〜50℃ generating water temp, is suitable from acetylene yielding rate, moisture quantity satulated by acetylene, solubility of acetylene, ammonia, hydrogen sulphide in water and supplied water temp. Still more, we found that the water quantities necessitate for lowering the water temp, are 10 literper 1kg carbide. We can not use the homogenous quality carbide, but these data are useful for construction the large capacity stationary generators.
