| 摘要 |
A gas torch assembly and its method of use are described for use in high-temperature applications such as a furnace, power generation station, pottery kiln and flame cutting and welding torches, which requires only inexpensive, low environmental impact, low pressure fuels such as propane gas and air; utilizes the initial internal combustion of the fuel gas to subsequently preheat air/oxygen and/or the fuel gas to well above ambient temperature; and dispenses with the need of arc-oxygen or arc-air cutting of metals.
