Coal Firing Boiler

Boiler Design for Modern Coal Fired Power Plants

2015-12-2 · With former designs of firing systems for hard coals, the possible minimum load was in the range of approximately 40% boiler load without back-up firing. By a proper adjustment of the mill size and taking into account the operating range of the burners, the minimum can be extended to approximately 25% of the boiler as shown in Figure 3 .
