Also a balanced ‘clean air flow’ distribution does not necessarily result in a balanced ‘dirty air’ or ‘coal flow’ distribution amongst the discharge pipes of a mill The focus needs to be on dirty airflow and coal flow balance measurements The relative flow distribution between burner pipes is assessed by

1 Utilize the Advanced Coal Flow Measurement (ACFM) equipment to accurately measure both air flow and coal flow rate in each pipe 2 Analyze the data to determine if the balance is within industry standards of 5 for the air flow balance and 10 for the coal flow balance 3 For those mills that are outside of industry specifications

Pulverized Coal Pipe Testing and Balancing By Richard F (Dick) Storm PE The first step in optimizing combustion system performance is balancing the air and fuel flowing through each of the plant's coal pipes—the pipes that convey the air fuel mix from the pulverizers to the individual burners in

Dec 15 2017 The Clean Air Act especially after amendments passed in 1990 drove a shift toward low sulfur coal as one of the main methods of reducing sulfur dioxide emissions from coal plants Since the predominantly subbituminous coal west of the Mississippi emits much less sulfur per unit of energy this trend favored western surface mines as a dominant

Clean air balance of within 2 of the mean This is a good starting point but by itself it does not guarantee fuel balance The fuel balance is dependent upon supplying equal amounts of pulverized coal to each individual coal pipe Clean air balancing is a mandatory prerequisite to balancing coal flow among coal pipes 3 Measure on a grid

The deflector liners from the zone where the coal has been entrained by the airflow to the elevation where the air meets the coal The lower position of the deflector liners redirects the primary airflow while it is still ‘clean’ and redirects it inward over the bowl rim where it entrains the coal The coal is then rolled
