Under a series work conditions, the quenching diameters and self-stability ranges of natural gas combustion in ceramics foam were determined experimentally, which might provide a guideline for the development and design of the porous media burners.

The performance of different diameter cartridges of several explosives was obtained by tests in this paper, and their misfire diameters were also measured by cone charges.

The assumption of unity Lewis number in the flamelet model of turbulent combustion is examined and the influence of differential diffusion and radiation on the flamelet structure, nitric oxide emission and extinction limit is investigated.

In a pilot scale reverse flow reactor with a liter of catalyst, catalytic combustion of typical industrial waste gas contaminated with volatile aromatic compounds (VOC) was systematically investigated, and the "temperature run-away"in the case of too high feed concentration and the "extinction of reactor" in the case of low feed concentration were observed.

Using the digital image processing technique and the laser tomography technique, a novel approach based on the turbulent intermittence was proposed here to describe the extinction process of turbulent flame.

The quenched samples of GAP/AN propellant after combustion extinguishment were obtained by a new quenching method.

Only in this year,extinguishment has occurred several times,especially for a DG 670/140-8 boiler, DCS data recorded showed some phenomena not encountered before when it extinguished.
