The regenerated lead alloy pot comprises a furnace body, a lead pot is arranged in a hearth in the middle of the furnace body, the furnace body is composed of a supporting layer arranged on the outer side and a heat preservation layer arranged on the inner side, and a heat storage cavity is formed by the distance between the inner wall of the heat preservation layer and the outer wall of the lead pot arranged in the hearth. A plurality of detachable combustors which are annularly distributed at the upper part of the heat storage cavity are detachably arranged on the supporting layer; the detachable combustor comprises a compressed air sleeve, a natural gas sleeve and an oxygen sleeve which are sequentially sleeved from inside to outside. The detachable combustors are annularly distributed on the heat storage cavity of the lead pan, and the outlets of the detachable combustors are tangentially arranged along the outer wall of the lead pan, so that the periphery of the lead pan is uniformly heated, the tail ends of the detachable combustors are prevented from being directly aligned to the outer wall of the lead pan for heating, and the service life of the lead pan is prolonged.

The utility model discloses a kind of combustion device and combustion system, comprising: hearth, hearth provides space for material combustion;Primary air chamber, primary air chamber is used to form primary air;Air distribution plate, hearth is communicated with primary air chamber by air distribution plate;Ammonia gas pipeline, ammonia gas pipeline is located in hearth and close to air distribution plate;Ammonia gas air cap, ammonia gas air cap is used to communicate ammonia gas pipeline and hearth, and the gas in the hearth is guided, the surface of ammonia gas air cap has ammonia cracking catalyst layer, ammonia cracking catalyst layer can at least part of ammonia gas that passes through ammonia gas air cap is cracked into nitrogen and hydrogen. Since the minimum ignition energy of hydrogen is lower than that of ammonia and the combustion temperature is high, hydrogen is more easily combusted than ammonia, which can improve the combustion characteristics in the hearth and enhance the effect of ammonia combustion, thereby reducing ammonia escape, while allowing more ammonia to react with nitrogen oxides, achieving the purpose of inhibiting the formation of nitrogen oxides.

The present application belongs to the technical field of solid composite propellant recycling, and particularly relates to a method for crushing waste solid composite propellant. First, a composite precipitate of iron hydroxide and aluminum hydroxide is generated by using ferric chloride hexahydrate and aluminum chloride hexahydrate, the precipitate is filtered and washed, and then is mixed with carbon nanotubes and ethanol for ball milling, and finally is calcined to obtain a nano composite grinding aid. After the nano composite grinding aid is prepared into a suspension, the waste solid composite propellant is crushed together with the suspension, and the crushed solid composite propellant particles are separated by screening. The nano composite grinding aid prepared by the present application can improve the performance of the propellant, and the crushing method is particularly suitable for combustion recycling of the waste solid composite propellant. In the combustion recycling, the combustion efficiency and energy release are enhanced, so that the recycling heat value and energy utilization rate of the propellant can be significantly improved.
