Professional Design Coal Hot Water Boiler With Customized Service

1. Three pass structure.
Function: ectend the flow of smoke and enhance the heat transfer.

2. Water-fire tube type.
Function:Fire tube:the flue goes through furnace, wing-shape flue and fire tubes to form three pass as said in the above.Water tube: water in some tubes rises after heating and some declines, which forms a natural circulation.

3. Wing-shape flue.
Function:reduce the smoke temperature of high temperature tube plate to slow down subcooled boiling. In this way, it can prevent tube plate cracking, reduce heat load of boiler bottom and prevent bulge.

4. Simple circulation loop, large sized down pipe and bottom container.
Function: Prevent tube explosion , increase the reliability of water circulation ,avoid deposition of debris and dirt,reduce fuel consumption and improving the operating time of boiler.

5. Optimally designed water feeding apparatus and steam separation device.
Function:The optimally designed water feeding apparatus reduces overhigh water level in shell high temperature zone due to overheat;

6. Optimally designed steam separation device is good for gravity separation, which makes the steam humidity lower than 1%, obviously lower than national standard of 4%;
Small overall dimensions and low boiler room investment cost. Function: The main heating surface is installed in the shell, and a boiler with less capacity can cancel the rear heating surface. Its overall dimension is obviously lower than other furnaces. The boiler below 100 steam tons (70MW) can be arranged in single layer, making the investment of the boiler room save more than 50% than other furnaces;
