Abstract
A method of compacting particulate material includes providing a primary fuel mixture of air and natural gas in a closed chamber enclosing a surface of the material to be compacted. An additive gas, such as hydrogen, having a higher combustion velocity is added to the primary fuel/air mix and ignited, creating an exothermic reaction which compacts the material. The additive gas increases the gradient of the pressure rise curve of the combustion. Various fuels and additive gases and disclosed.
