Abstract: An apparatus which can confine almost entire available energy in the vicinity of ignition point during a laser-induced ignition process is proposed. Multiple reflection by a cavity surface when a small diameter laser beam is directed into the cavity is utilized in laser ignition. Shadowgraphs of the early stages of the combustion process for quiescent methane/air mixtures show that a hot gas jet emerges from the cavity. During subsequent flame propagation, both similarities with and difference from conventional spark ignition processes are observed, depending on the cavity size and the concentration of mixtures. With laser cavity ignition, the chamber pressure increases relatively rapidly and higher maximum pressure can be achieved. As a result, the combustion duration for laser cavity ignition is decreased relative to laser-induced spark ignition.

Further, electrical energy can be passed through the fuel conduit, raising the temperature of the conduit to a temperature above which the fuel will ignite when combined with the oxidant.

Abstract: A premix burner assembly for heating the combustion chamber of a dryer for an HMA plant, soil remediation plant, or the like is designed to meet the very low emission limitations that are imposed in certain areas such as the southern portion of California. The burner assembly includes a burner, a primary nozzle, an air source connected to the burner, a fuel source, and a fuel injection system connected to the fuel source and to the burner.

Burner efficiency is increased and emissions are further reduced by employing air distribution and control devices upstream of the fuel injection system and by carefully controlling the supply of both air and fuel to the burner.

Abstract: Disclosed is a gas lighter. To use the gas lighter, first, the push-down member is depressed. As a result, the rotary body rotates and the engage pawl of the rotary body engages with the ratchet teeth of the ratchet. This rotates the ratchet, causing the rotary ignition means to rotate. As the rotary ignition means rotates, it rubs against the flint to make sparks, which ignite the gas injected from the gas injection means. To stop using the gas lighter, the depression of the push-down member should be released. Consequently, the push-down member returns by the returning elastic member so that the rotary body rotates in the opposite direction, thus disengaging the engage pawl from the ratchet teeth. At this time, the ratchet teeth and rotary ignition means do not rotate.
