Water for the Boiler - Spirax Sarco

Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high

CHAPTER 3 COMBUSTION CALCULATION

Methane is burned with air in a PA Hilton boiler to produce hot water oof 55oC. The fuel is fed at a rate of 7 kg/hr at 25 C, the air enters the boiler at a rate of 130 kg/hr at 42.5oC, and the water enters the boiler at a flow rate of 1000 kg/hr at 10oC. The composition of the dry flue gas leaving the boiler at 700oC are found to be 0.9% O 2

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
