A gas catalytic combustion element and a gas powered heating device |
摘要 |
A glue gun (10) comprising a body member (3) in which a glue accommodating and melting chamber (4) for receiving stick glue is formed and combustion chamber 910) is also formed for accommodating a gas catalytic combustion element (14). A temperature responsive valve (25) controls the supply of fuel gas to the combustion chamber 910) for maintaining the temperature of the body member (3) at approximately 140° C. A thermal mass (2) provided by a screw (27) is clamped onto a tab shaped portion (30) of the bas catalytic combustion element (14), and maintains the temperature of the tab shaped portion (30) above the ignition temperature of the gas catalytic combustion element (14) during periods of fuel gas interruption to the combustion chamber (10), so that when the temperature responsive valve (25) restores the supply of fuel gas, the tab shaped portion (30) immediately commences to convert fuel gas to heat by catalytic reaction, thus rapidly raising the temperature of the gas catalytic combustion element (14) to its ignition temperature. |
