Industrial boiler can be divided into fire tube boiler, water tube boiler, and water-fire tube boilers from the internal structure. So what is the difference between water tube boiler and fire tube boiler?
First, the water tube boiler refers to a boiler which a combustion chamber and a heating surface are arranged outside the drum, water and steam flow in the tube.
A fire tube boiler is also called a shell type boiler, carton steel steam boiler, the flue gas generated by the combustion of fuel flows through the pipe, heating the water, steam or steam-water mixture outside the flue tube.
Difference between water tube boiler and fire tube boiler
1. Structure: The water tube boiler has a complicated structure, which is composed of two parts: the boiler body and auxiliary equipment.
2. Water quality: water tube boiler and fire tube boiler are different in water quality. Water tube boilers have high requirements on water quality. If the water quality is poor, it will have a great impact on the performance of the boiler, and it will also bring great safety hazards. The latter fire tube boilers have low water quality requirements, but the boiler fouling takes longer Not conducive to heat absorption, it will increase in fuel consumption.
