The attemperation water, which is 2-5% of the total steam flow, may come from the boiler feed water pump outlet, or further downstream, just before the economizer inlet. From an energy efficiency standpoint, attemperation would be more effective and require lower flows if sprayed further downstream. The risk of waterRead More

Optimizing Combustion. The boiler is often a good place to begin to look for heat rate improvements. The operating conditions controlled by adjusting fuel and air flow rates among burners  adjusting mixing patterns of coal and combustion air and adjusting economizer O2 level. Changes to these parameters affect quantities suchRead More
