Structure principle of Central Heating Hot Boiler Systems
In the natural circulation central heating hot boiler systems, the inlet and outlet water are piped from the top of the pot. By the water intake pipe, the inlet water drop pipe is guided into the front and side of the header, and heated up through the water cold wall tube.
In front of the drum, the back end is provided with a water barrier at the boundary between the downfall and the rising flow, and only the lower half of the drum is cut off. For forced circulation, the inlet water is connected to the front lower header, the front water wall pipe rises to the top of the drum (when the front water wall drop pipe is canceled), and then it is transferred to the side water wall drop pipe to the side bottom header, and then the side water wall pipe is put up to the up drum.
From the front convective tube bundle down to the down drum, and finally on the top, between the pan tubes. A few more twists and turns out the water from the back of the pot. Forced circulation central heating hot boiler systems do not carry economizer.
