Product thermal capacity: 2-10 t/h
Working pressure: 1-2.5 MPa
Product thermal capacity: 2-10 t/h
Working pressure: 1-2.5 MPa
Product thermal capacity: 1.4-7 MW
Working pressure: 0.7-1.25 MPa
1. The water tube boiler has a wide range of pressure adaptation, which can break through the pressure limit and meet the steam supply requirements of more than 2.5MPa. The fire tube boiler is limited by the material wall thickness and pressure, and is used under the pressure of 2.5MPa.
2. The water tube boiler of three passes can be a large-scale boiler, and the water-tube structure is usually used for boiler capacity above 35t/h. The fire tube boiler has the characteristics of compact structure. Under the same output, its appearance and equipment weight are lower than those of the water tube boiler.
It is found that the fire-tube boiler and water-tube boiler have their own advantages and disadvantages, and each enterprise should choose the appropriate boiler type according to the actual demand of its own production line, such as steam demand, reasonable boiler room area, boiler operation cost and maintenance simplicity, etc.
