Atmospheric pressure hot water boiler, the working principle of the hoist
The earliest no opening and closing valve design, the atmospheric pressure boiler a furnace, the stove staff have to immediately close the return valve to ensure that the water does not turn back.
On the front of the drum, the rear end is provided with a riser at the boundary between the descending and rising water flow, and the watertight plate only cuts the lower half of the drum.
Natural circulation of hot water boiler, into the water from the top of the top of the tube, the water into the distribution pipe will be directed into the downfall into the front and side under the box, through the water pipe wall heating up.
Mainly in order to prevent the system water back into the boiler, because the atmospheric pressure boiler is generally designed to have a mouth of the water tank or normally atmospheric discharge tube, if the water back from the system back to fill the boiler, the system will all overflow from the boiler
