A burner with compressed air forced feed.
– heating of ferrous metal and nonferrous metal before
welding and surfacing, removal of welding deformations;
– heating of interference fit unit at assembly and disassembly;
– fusing bituminous roll material while roofing and waterproofing work;
– drying of casting molds;
– flame treatment of agricultural animals’ carcasses.
The torch “DONMET” 280 is designed for heating of products made of ferrous and non-ferrous metals, non-metallic materials; heating of metals before surfacing and welding; flowing of bituminous rolled material during waterproofing of various structures. It is also used for heating of plastic tubes before bending, drying of concrete panels and brickwork; as well as for flame treatment of farm animals’ carcasses.
The torch operates on an air-gas mixture using natural gas (methane) as gas fuel. It is allowed to use propane-butane as gas fuel.
The torch basic parameters conform with ISO 9012:2011.
|Flame jet length no more than, mm||300–800|
|Natural gas (methane)||0,01…0,1|
|Natural gas (methane)||4,2…6|
|Rate of heat flow no less than, KW||Natural gas (methane)||40…57,5|
|Flame temperature, 0С||1870°|
|torch length no more than, mm||1185|
|torch weight no more than, kg||1,4|
Note: one kilogram of liquid propane-butane mixture when evaporates generates around 500l of gas.
