The addition of tubes inside the drum containing the water increases the heating surface. The heating surface is the part of the boiler with water on one side and the gases of combustion on the other. By increasing the heating surface, more heat is extracted from the gases of combustion by the surrounding water. This results in a more rapid water circulation and faster formation of steam bubbles. When larger quantities of steam are released, the thermal efficiency of the boiler increases. Thermal efficiency is the ratio of the heat absorbed by the water to the heat supplied from the fuel. Modern fire tube boilers with improved design and heat transfer rates have achieved thermal efficiency …Get Price
