DZLseries single drum coal
fired steam boiler
* Thisthread boiler smoke pipe, arch tube sheet, wing flue structure, is the firstvictory in national development and National patent in 1991, after nearly twodecades of continuous improvement and perfection of its structure is morereasonable, environmentally friendly energy.Effects become moreprominent.
* for the application of different fuels, chain grate andreciprocating grate is divided into two series. With energy, strong radiationarch, can be applied to all types of bituminous coal combustion.
* with highstandards, high-quality auxiliary equipment, accessories, automated control toensure the boiler is safe, stable.
* Compact ,1-10T / H fast assembly ,15-35T/ H large assembly, single-layer arrangement, one-time investmentprovince.
* boiler capacity of 1-35T / H (0.7-29MW).
