The invention provides a composite incendiary agent for destroying ammunitions and a preparation method of the composite incendiary agent. The composite incendiary agent is prepared from the following components in percentage by weight: 60%-70% of a main reaction medicament, 1%-5% of a diluent, 5%-10% of a gas making agent and 20%-30% of an auxiliary medicament, wherein the main reaction medicament is prepared from 0.3-1.5 parts of iron sesquioxide, 1.6-2.9 parts of ferroferric oxide and 1 part of powdered aluminum; the dilute is alumina powder; the gas making agent is prepared from 0-5 parts of silicon carbide powder and 6 parts of potassium nitrate powder; the auxiliary medicament is prepared from 6 parts of copper oxide powder, 4 parts of powdered aluminum, 1-3 parts of silicon dioxide powder, 5 parts of nickel powder, 0-3 parts of calcium fluoride powder and 0-3 parts of calcium carbonate powder. The composite incendiary agent is stable, the combustion pressure is uniform, the fluidity of generated metal melt is good, the jet velocity meets incendiary requirements of the ammunitions, and the composite incendiary has strong capacity for smelting shells of projectiles the strong capacity for igniting explosives and does not detonate the explosives. When applied to the destroying of the ammunitions, the composite incendiary agent is low in dosage, high in action speed, relatively safe, efficient and convenient.

The invention relates to an ignition device for a biomass gasification furnace and a using method thereof. In the device, an ignition bar formed by a heating wire and a ceramic tube element is vertically arranged in a three-way inlet tube of the biomass gasification furnace; the upper end of the ceramic tube element wound with the heating wire is positioned above a grate; the biomass gasificationfurnace are filled by granular biomass materials and compacted; the biomass materials are closely contacted with the heating wires; after the ignition bar is electrified, the biomass materials at theperiphery of the ignition bar is directly heated; a draught fan is opened after 10 to 20 seconds of heating, air is introduced to the bottom of the gasification furnace from the lateral side of the upper section of the ignition bar; the power supply of the ignition bar is closed after the electrification lasts for 10 to 20 seconds; and the ignition bar is twitched downwards and is rotated to ensure that the ignition bar is retracted inside the three-way inlet tube, the ignition bar is separated from the biomass material subjected to high-temperature gasification reaction with the ignition bar, and the air is introduced into the biomass gasification furnace from clearance between the upper end of the ignition bar and the inlet tube to maintain constant performance of the gasification reaction. The ignition device has the advantages of high success rate of ignition, short ignition time, simple and convenient operation and safe use.
