The role of biomass boiler drum

　　Boilers are divided into double drums and single drums according to the drum. The double-drum boiler has an upper drum and a lower drum, and the upper and lower drums are connected by convection tube bundles. The single drum has only one upper drum.

　　The role of biomass boiler drum:

　　1. Connect the ascending and descending pipes to form a natural circulation loop, accept the feed water from the economizer, and deliver saturated steam to the steam superheater at the same time;

　　2. A certain amount of saturated water is stored in the drum, so the water supply of the boiler is interrupted for a short time, and the boiler accident will not occur immediately, and it also has the function of buffering the air pressure;

　　3. The internal device of the drum can purify the steam and live the steam with good quality.
