MODELING OF PULVERIZED COAL COMBUSTION FOR IN …

Low NOx burner and air staged combustion are widely applied to control NOx emission in coal-fired power plants. The gas-solid two-phase flow, pulverized coal combustion and NOx emission characteristics of a single low NOx swirl burner in an existing coal-fired boiler was numerically simulated to analyze the mechanisms of flame stability and in-flame NOx reduction.

15/10/2009 · Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up. Flame failure in a boiler
