Morocco 4Ton Coal Fired Boiler For Feed Mill

Features of DZL coal boiler
1. With the novel furnace structure, the boiler can tackle the deformation of bulge caused by directly heating the bottom of the drum.
2. The boiler can avoid the crackles happening in the plates.
3. the drum adopt single pass threaded pipe, so it can not only strengthen the heat transfer effect but also has the function of self-cleaning gray at the same time
4. Novel arch design makes coal combustion and coal adaptability strong.
5. Grate side sealing structure avoids the shortcomings of uneven ventilation and burning out side sealing.
6. Separate adjustable wind chamber under the fire grate is equipped and wind is fed from two sides. It adopts new type crack screw wind adjustment structure so that the wind adjustment and ventilation cross section proportion is 100%. Thus, it is easy to adjust and the wind is distributed symmetrically.
