What is the cause of boiling turbidity on the surface of the gas charge layer?
TIME:2017-2-6 13:11:54 | VIEW:
The normal layer surface should be clear, and the surface of the layer can be viewed directly from the fire detection orifice. But when the use of new small particles of coal, or screening efficiency is not high, a large number of pulverized coal into the furnace; or rain coal damp, pulverized coal sieve is not clean; or the use of mechanical strength or low heat intensity Coal, in the above factors, the surface layer may appear small particle powder to be raised by the airflow blowing, boiling state, when the gas flow increases, this time the boiling state increased, so from the fire hole to the furnace Inside the spy is very turbid.
In this case, should actively improve the quality of coal into the furnace, that is to reduce the pulverized coal into, and should reduce the gasification intensity, or a long time to continue, the furnace will further deteriorate, followed by gas heat will decline.
