Construction of 113 t/h Boiler for
Appleton Estate, Jamaica
Appleton is where the famous Appleton rum comes from so the traditional sugar factory steam balance is distorted by the extra steam demand of the distillery. J Wray and Nephew, the owners, therefore wanted a new, more efficient boiler to replace their existing units. As the one boiler was to replace all of the others it had to be a reliable unit. There was also a timing issue with respect to upgrading HP steam users so the boiler had to be designed for a lower initial steam pressure.
The principle characteristics of the boiler are:
|Evaporation||113 t/h||Feedwater Temperature||105 °C|
|Steam Pressure||3 620 kPa||Bagasse Moisture||48 %|
|Steam Temperature||399 °C||Boiler Efficiency on GCV||65 %|
The initial steam pressure is 3 100 kPa.
It can be seen that the boiler is top supported. This is because Appleton is in a seismic region and it is more economic to select a top supported boiler for such requirements.
