What are the types of boiler structures? I believe everyone is curious, so today we will briefly introduce them.
What are the types of boiler structures? In fact, common types of industrial boilers include water tube boilers, fire tube boilers, and water fire tube boilers.
A water tube boiler refers to an industrial boiler in which a combustion chamber and heating surface are installed outside the drum, causing water and steam to flow inside the tube. The structure is relatively complex, and the steam water system mainly includes the drum (steam drum), header, water-cooled wall, convection pipe bundle, economizer, and superheater, etc; The combustion system mainly includes the burner, furnace and flue, air preheater, etc. The structural forms include water tube boilers, straight water tube boilers, curved water tube boilers, etc.
A fire tube boiler, also known as a shell boiler, is a type of boiler in which the smoke generated after fuel combustion flows through the fire tube or smoke pipe, heating the water, steam, or steam water mixture outside the fire tube or smoke pipe. The basic structure is to install small cylinders, tubes (referred to as “fire tubes”), or other shaped shells (referred to as “furnace liners”) inside a large cylinder (pot shell). The fire tubes are isolated from the large cylinder and form a jacket, which contains water. The fire tubes and furnace liners act as combustion chambers and flues, accommodating flames or smoke. The heat generated by combustion or smoke is transmitted to the water supply through the wall of the fire tubes.
The water fire tube boiler is a new type of steam boiler developed on the basis of horizontal external combustion fire tube boilers.
