1 The ability of coal to release a combustible gas has long been known.

2 The result shows that the content of combustible gas is far lower than the lower explosive limits and there is no the explosion danger in heating furnace.

3 The ensuing drop in oxygen and combustible gas levels should be noted.

4 A type of combustible gas alarm device, which is controlled by single chip microcomputer,[] is introduced.

5 The main products are toxic combustible gas detector, for flue gas monitoring systems, dust analysis systems.

6 A combustible gas probe is arranged between the exit of the channel of the air casing and the exhaust gathering pipe.

7 The longest in Asia, the world's second - combustible gas combustion test system.

8 Once combustible gas is ignited , which often leads to explosion, the explosion pressure wave and propagation of flame will be influenced by many factors.

9 The detection and monitor of the combustible gas and the noxious gas have become the desiderative tasks of enterprises at present.

10 A method suitable for calculating the burning rate of combustible gas in CFBC has been created.

11 Working Medium: Water, Oil, Non - corrosive and non - combustible gas.

12 According to the virtual instrument technology, an integrated test system is designed to get properties of combustible gas sensor under various condition.

13 The clogging of a briquet hole is prevented; a plurality of combustible gas is provided for the combustion chamber, promoting the sufficient combustion of the briquet.
