A coal fired steam boiler uses 3000kg of coal per hour. Air required for combustion is 15.5 kg per coal at a barometric pressure of 98.2 kPaa. The flue gas has a temperature of 285C and an average molecular weight of 30. Assuming a ash loss of 11% and an allowable gas velocity of 7.5m/s, find the diameter of the chimney.Get Price
Boiler tubes, usually are made from carbon steel and are subject to. high rates of heat transfer, bending stresses due to uneven heating, especially at expanded or welded joints into headers or drums, external erosion from burners and flue gas, possible corrosion on the boiler side, and; occasional manufacturing defects.Get Price

The steam strips the dissolved gas from the boiler feedwater and exits via the vent valve at the top of the domed section. This vent valve should not be opened sufficiently the deaerator will not work properly, causing high oxygen content in the feed water going to the boilers. Should the boiler not have an oxygen-content analyser, a high level Get Price
