Background technique
Igniting and underrun stage are the operating conditions that station boiler certainly exists, in the two operating conditions,
Breeze gas flow temperature and environment temperature are lower, it is difficult to absorb enough ignition heats, realize stable kindling and burning.In order to realize
Above-mentioned purpose, the general fuel or additional High temperature ion body and hot wind ignition etc. being readily burned by the oil and gas that burns in scene
Heat source.
Due to the raising of oil, coal price lattice, currently, few (micro-) oil drop fire and oil-free plasma ignition is widely used in coal fired power plant
Etc. technologies, but there are some defects for these technologies.For few (micro-) oil drop fire, in Publication No. CN 101093077A
State's patent, " a kind of eddy flow powdered coal burner lit up by tiny oil " also need arrangement oil although reducing in the dosage of oil
It stands, this necessarily spends the expense for security maintenance and land used, and compared with the igniting of conventional fuel oil, economy is not obtained significantly
Improve；And plasma igniting is then that the starting the arc is contacted using DC current, under high-intensity magnetic field control, so that with certain pressure
Pure air generate directed flow air plasma, formed localized hyperthermia, to light by coal dust be then sprayed into burner hearth
Kindling, such as the Chinese patent of Publication No. CN 1230556A, " burner on plasma ignition device ", this igniting
Technology is there are cathode operating condition is severe, the short feature of working life, and the requirement simultaneously for coal characteristic is also higher；For heat
Wind igniting, such as the Chinese patent of Publication No. CN 1490562A, " coal powder boiler high temperature air ignition method and its device ",
There are high temperature air generation and the problems of air transported in method.
For lighting operating condition and running on the lower load, it is important to so that can breeze airflow reach ignition temperature.Many institutes
Known, the chemical reaction velocity of combustion of hydrogen is fast, so that centralized release energy, ignition temperature can be more than 2000 DEG C.Therefore, sharp
It, can firing coal-dust airflow with the localized hyperthermia of combustion of hydrogen.The technology relative maturity of electrolysis water hydrogen making, publication number CN
The Chinese patent of 101187473A, " hydrogen and oxygen mixed gas burner ", a kind of hydrogen and oxygen mixture combustion of the patent disclosure
Burner, but the burner does not have coal dust and ignites function；The Chinese patent of publication number CN 101532678A, " coal burning boiler of power station
Brown Gas (oxyhydrogen) ignition system " discloses a kind of method of power plant's oxyhydrogen coal dust booster burners, but the technical solution
Only simple illustration does not suggest that specifically how to realize using oxyhydrogen as ignition source.
