A kettle reboiler (Figure 10.1) consists of a horizontally mounted TEMA K-shell and a tube bundle comprised of either U-tubes or straight tubes (regular or finned) with a pull-through (type T) floating head.The tube bundle is unbaffled, so support plates are provided for tube support. Liquid is fed by gravity from the column sump and enters at the bottom of the shell through one or …Learn More
water. Fire tube boilers have low initial cost, and are more compacts. But they are more likely to explosion, water volume is large and due to poor circulation they cannot meet quickly the change in steam demand. For the same output the outer shell of fire tube boilers is much larger than the shell of water-tube boiler.Learn More

What is Steam Boiler? A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam …Learn More

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.Learn More

The heat in the steam produced is about 95% of that lost by the gases passing through the boiler. Heat lost by hot gases = V s ( t 1 − t 2) MJs − 1, where V = m 3 gas/sec, s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs ( t1 − t2 )MJ s −1, t1 and t2 = temperature of hot gases before and after the W.H. boiler, °C.Learn More
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell.
