The Advantage of Flue Gas Cycle Three Pass Structure Boiler

The first return process is arranged in the lower part of the middle of the boiler body, the third return is the right and left sides of the combustion chamber, which is located in the low water level area and no radiation loss, and the second return pipe group is placed above the symmetrical third return pipe group. The advantages of this heat transfer arrangement, large-capacity combustion chamber (furnace) can ensure that the gas or liquid fuel can be fully burned, the uniform spread of flue gas to reduce NOX emissions, clean and environmentally friendly. ZBG WNS series boiler is the use of three principles of flue gas cycle design.

The advantages of the three pass structure boiler include: a. Combustion chamber designed for low arrangement is completely contained in the water, the heat of the radiation after the transfer of water to the pot, then instantaneous movement, the water generated by the huge temperature difference generated by the agitation Natural convection, to promote the boiling of the steam rise cold water down, never stop the symmetrical circulation process to achieve the best heat transfer, to ensure uniform heating of the boiler. b. Boiler tube left and right symmetrical layout of the boiler to withstand the thermal stress on the left and right, greatly extending the life of the boiler; c. ZBG WNS series design not only retains a large water level safety, but also makes the steam moisture content is low ,which ensures the quality of steam.
