An overview of problems and solutions for componen

Dec 21, 2017· In water tube boilers, the water to be heated flows in the tubes and the combustion gases flows around the tubes, thus converting the water into steam. These types of boilers are used where high steam and pressure are required. The capacity of these boilers varies from 4500 to 1,20,000 kg/h [3, 4].
