80 results about "Pyrolant" patented technology

A pyrolant (from Greek pyr, fire) is an energetic material that generates hot flames upon combustion. Pyrolants are metal-based pyrotechnic compositions containing virtually any oxidizer. The term was originally coined by Kuwahara in 1992, in a paper on magnesium/Teflon/Viton, to distinguish between compositions that serve as propellants and those yielding hot flames which are not necessarily suitable for propellant purposes.

ActiveCN107804868BPromote environmental protectionPlay the beneficial effect of environmental protection and energy savingIncandescent ignitionChemical industryCombustionControl system
The invention discloses a plasma gun ignition blow-on method of a boiling chlorination furnace. High energy plasma generated by a plasma gun is taken as start energy for ignition and heating; compressed air is taken as the combustion improver; a boiling chlorination reaction raw material bed is gradually heated and ignited in a sectional type; after ignition and heating, the control system of a chlorination reactor is started, and the ignition-heating and device starting-running are seamlessly jointed. The technology is characterized in that (1) high energy plasma generated by a plasma gun istaken as the start energy for the ignition and heating of a boiling chlorination furnace, and the plasma is simple and is easy to control; (2) the raw materials are used to build a bed; other fuels such as coal, oil, gas, and the like, are not needed; the burning does not generated any smoke, and the technology is clean and environmentally friendly; (3) petroleum coke of the raw materials for building the bed is burned by the plasma flame, fine petroleum coke is burned at first, then coarse petroleum coke is burned, the burning is fast, the temperature is easy to control, energy is saved, andthe efficiency is high; and (4) ignition-heating and device starting-running are seamlessly jointed, and the production efficiency is high.

Carbon monoxide emission reduction sintering synergist and use method thereof

The invention discloses a carbon monoxide emission reduction sintering synergist and a use method thereof, and relates to the technical field of fuel combustion supporting. The carbon monoxide emission reduction sintering synergist is prepared from the borax, the alkaline earth metal oxide, the oxygen producer, the alkali metal salt or the alkali metal hydroxide, the desulfurizing agent and the combustion improver as raw materials, and the prepared sintering synergist can provide sufficient oxygen for fuel in the combustion process by adjusting the composition and the proportion of the raw materials; the combustion speed of fuel is increased, emission of carbon monoxide is reduced, and sufficient combustion of the fuel is achieved.
