The invention discloses an ignition system of an energy-saving eternal lamp utilizing exhaust gas. The ignition system comprises eternal lamp ignition units and natural gas sources which are connected with the ignition unit, wherein the eternal lamp ignition unit comprises an eternal lamp igniting device; each eternal lamp igniting device comprises an eternal lamp loop and an ignition loop; the multi-gas-source eternal lamp ignition system is characterized by also comprising a flammable exhaust gas source, a liquid separation tank and a classified water sealed tank, wherein the flammable exhaust gas source is connected with the liquid separation tank and then connected with the classified water sealed tank; the eternal lamp ignition unit comprises at least two sets of eternal lamp igniting devices; the classified water sealed tank is connected with the ignition loop of at least one set of eternal lamp igniting device; the natural gas sources are connected with the ignition loops of all sets of eternal lamp igniting devices in the eternal lamp ignition unit; the flammable exhaust gas source is connected in parallel with the natural gas sources. The ignition system disclosed by the invention can be used for igniting an eternal lamp by utilizing exhaust gas, and also utilizing the gas sources in a multi-stage manner, and is safer and more reliable.

A method and system for a helicopter blade emergency detachment system that has an activator in the cockpit to initiate the system, an ignition train to provide the detonation signal, a transfer system at the base of the main rotor shaft to move the signal from the stationary helicopter to the rotating blades, and explosive charges located at the root of each main bearing-less rotor blade to separate the composite blade from the main rotor. These four components interact in the way described to enable the blades of the helicopter to be detached during an emergency, thus increasing the stability of the aircraft during a hard landing and/or allowing for the use of an occupant ejection seat or parachute while the helicopter is still in flight.

The invention discloses a temperature-controllable biomass burner, which comprises a shell, a fire tube, a fire mouth at the end of the fire tube, a fire grate, a combustion chamber at the upper part of the fire grate, an ash chamber at the lower part of the fire grate, an ash discharge port at the bottom of the ash chamber, a feeding system which is connected with the combustion chamber, an explosion-proof port which is installed at the top of the combustion chamber, an air distribution and ignition system which is connected with the fire grate, an access door which is arranged below the shell, and a control system which is installed outside the shell. By adopting the method, the temperature-controllable biomass burner provided by the invention has the advantages that the temperature of the fire mouth of the combustion chamber can be controlled, and not only can the influence caused by too low temperature be avoided, but also the damage caused by too high temperature to equipment can be avoided.
