Product Description
DZL series industrial coal fired boiler is a new type boiler designed according to the market demand. The advantages of DZL steam boiler is compact structure, simple volume, time saving and material saving, high reliability, cushion efficiency and strong overload capacity. The electric control realizes the stepless speed adjustment of the grate, alarm of limit parameter and interlock protection. This boiler is widely used, is the vast number of small industrial and mining enterprises with steam production and people’s first choice for heating.
Technical Advantages
Low Cost
Compact structure, save boiler house infrastructure investment. Fast heating and boosting, less coal consumption, high thermal efficiency, can save 25-30% of coal.
High Efficiency
High efficiency heat transfer threaded pipe is used to enhance heat transfer. The flue gas longitudinal scour convection tube bundle makes full use of heating surface to improve boiler efficiency.Stable operation, easy adjustment, sufficient output, overload capacity.
Grate air warehouse into the warehouse, the wind volume of each warehouse can be adjusted independently, grate stepless speed regulation, adapt to a wide variety of coal, full combustion.
Natural ventilation, no need for blower and induced draft fan, no noise.
Easy to Maintain
Scale is easy to remove, changing the tube. Because the flue gas multi – return multi – cycle to achieve the effect of natural dust removal.
Complete automatic control and monitoring instruments, high degree of automation, safe and reliable, easy to operate.
