Reciprocating grate coal hot water boiler
Water tube forced circulation boiler
High-efficient combustion low emission

Take QXW29-1.25/130/7-H as an example:

Patent:
Fly ash inner circulation fluidized reburn device based on high-temperature separation
----------------------------
Main Features:
1. Large-volume, efficient combustion, low pollution
2. Reciprocating grate, simple structure and sufficient combustion.
3. Two kinds of water circulation, reliable, safe and efficient
4. totally-enclosed membrane water wall, good sealibility, good appearance
------------------------------
Detailed information:
1. Reliable water circulation structure
It adopts full membrane water wall, self-supporting structure. The drum, downcomer and rising tube together form auxiliary water power of forced circulation, and the rising water speed of membrane water tube is ensured above 0.5m/s, essentially guaranteeing high mass velocity and completely eradicate the danger of soaring of the wall temperature.
2. Reliable power failure protection capacity
A drum of 10m3 water volume provides water power for natural water circulation. With large-diameter corner tube, the water capacity of the boiler proper reaches 37m3, which provides sufficient time for dealing with power failure emergency and efficiently prevent vaporization and water hammer.
The water wall all adopts rising water circulation pattern, therefore, natural circulation will be triggered as soon as there is power failure, efficiently preventing dangerous occasions such as backflow and stagnation.
3. U-shape slot-type inertia separating gear is set between the last convection bank and air pre-heater, collecting fly ash into the dust mouth, and furthest reduce original dust emission concentration.
