Product Discription
DZH Series Manual Coal Fired Steam Boiler
DZH series manual coal fired steam boiler adopts mobile grate with auxiliary equipment such as blower, ventilator, economizer, dust collector, automatic water treatment, water pump, steam header, control cabinet, valve, equipment etc. . This series of boilers is an economical boiler with few auxiliary equipment, less machine failure, low maintenance cost, easy operation, saving time and material. Applicable to all types of coal fuel, environmental protection and moderate pricing are the first choices for steam processing production lines for SMEs.
Product Features
1. Easy installation:
Boilers are generally installed out of the factory quickly, which is convenient for transportation and site installation, greatly shortens the construction cycle, saves installation costs, and enables the boiler to be put into production in time.
2. Reliable operation:
Boiler heating surface layout is reasonable, water circulation is smooth, ensure that the heating surface cooling in time, thus effectively ensuring the safe operation of the boiler.
3. Maintenance and maintenance are convenient:
The boiler drum is equipped with manholes, which can be inspected and repaired. The smoke box in front of the boiler is easy to open, and the personnel can check it conveniently and clearly, which provides a good condition for the correct treatment.
4. Full combustion:
With secondary air and reasonable furnace design, the fuel can be fully burned and the black smoke can be eliminated.
5. High efficiency grate:
Boiler grate is matched with biomass fuel, which avoids air leakage, fuel leakage and uneven ventilation. It is easy to operate and has obvious advantages compared with ordinary grate.
6. Cleaning is convenient:
The installation of multiple ash clearing holes on the boiler can effectively clear the ash in time, avoid the operation obstacles and the decrease of thermal efficiency caused by the ash accumulation of the boiler, and ensure the stability of the boiler load.
