A CFB boiler typically has one or more high temperature cyclone-type solid separators. These cyclones can be built separately, Fig. 10.8, or integrated into the furnace. Small-diameter cyclones would have a higher collection efficiency, but …Get Price
This method calculates boiler efficiency by using the basic efficiency formula η=(Energy output)/(Energy input) X 100 In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred.Get Price
2014/3/20 · Boiler to be drained when drum metal temperature has dropped to 90 deg. C. Rinsing : Rinsing operation is carried out by filling and draining method. Rinsing should be done till drain water is free from alkali and PO4 content has reduced to less than 50 ppm.Get Price
2007/1/1 · In a fossil fuel fired boiler, flame temperature is generally less than 1500 C, so NO x formation is dominated by fuel NO x mechanism. The high HCN concentration presenting in the vicinity primary air nozzle is in favor of controlling the early stage combustion in a reducing atmosphere, and thus fuel NO formation might be suppressed or part of the formed NO can be …Get Price
