Nov 24, 2016 · Q.(A).What is the affect of sulfur in coal when used in boiler? Sulfur will get oxidized to SO2 and fraction of SO3 and will react with water to form sulfuric acid and this occurs at a temperature called the acid dew point which normally is about 120 oC. The sulfuric acid so formed corrodes the steel when it comes in contact with it.Get Price
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

It would be quite difficult to make a boiler with bloomery iron. The blast furnace only showed up around 1100. The Romans could certainly have made a Newcomen-style low-pressure steam engine; the first boilers were made of lead and copper (though they quickly switched to iron). However, those are of only mild usefulness.Get Price

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low …Get Price
