The basic characteristics of natural gas during combustion are studied by measuring ionic current in a straight conduit combustion bomb, which can control the change of temperature and A/F to avoid the unstable state of combustion and ionic current resulted from the cyclic variation in the engine experiment.

Analysis of ionic current signal character in long-straight tubular combustor and its application in engine;

For the direct-flow burner special laying style,the inner air dynamic of this kind of burning style boiler was studied and the problem of slagging was solved.
