This boiler was specified to operate at an initial pressure of 3,100 kPa even though its design operating condition is 4,100 kPa. Although that might sound simple, it is not because the different specific volume of steam at the lower pressure means that the volume flow [which dictates the steam/water separation technology] is 33% higher. The boiler is equipped with TES pinhole grate, triple drum bagasse feeders and pneumatic spreaders. ![]() This picture was taken in mid November 2007. |
