Introduction Fire Tube Steam Boilers are the most traditional technique for the production of saturated steam, high pressure hot water or superheated steam for a range of outputs from 250 to 50 000 kg/h (175 to 34 000 kW). Operating Principle Steam is generated by heating a large volume of water in a pressurised drum by means of hot gases, which are produced from the combustion of liquid or

2017-6-3 · It is assumed that boiler feedwater preheat from ambient to condensate temperature (usually about 200°F) will be done by heat exchange against a process stream, outside the boiler island battery limits, with only some "top-up" heat recovery against hot boiler blowdown. The use of steam to preheat boiler feedwater was common when energy

Absorbers Absorbers bring gas and liquid phases in contact, so that contaminants in the gas phase absorb into the liquid phase as a result of their interaction. One example of a spray column is in the absorption of sulfur dioxide from coal-fired boiler exhaust gases. Advantages Disadvantages Low pressure drop. The geometry of the trays
