and a buildup of scale inside the boiler. One way to lower the amount of dissolved oxygen in feedwater is use a sparge tube. This injects steam into the feedwater to increase the temperature to 160°F to180°F or so to remove oxygen. Scale is a very effective insulator that will cause a loss of heat transfer efficiency and eventually tube

heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost.

⑥ Press the tube through the water or gas can be divided into categories: fire-tube boilers, water boilers and fire tube boiler combined. ⑦ by the use of the boiler is divided into: life, boilers, industrial boilers, power station boilers and hot water boilers. 3.What is the fire-tube boilers?

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) 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

The stack temperature of 3 pass will be lower than that of 2 pass boiler, of the same design and operating pressure. Efficiency is more than two pass boiler. Each pass in boiler should be designed with cross sectional area to achieve optimal flue gas velocity, which in turn maximizes heat transfer while also minimizing performance robbing sooth
