Boiler Description
DZH series coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution. This series boiler is single drum horizontal type shell boiler, the combustion equipment is moving grate. The fuel could be II class bituminous coal and biomass fuel, the diameter of coal should be 6-25mm, and ash content should be less than 32.4%, and for the biomass fuel, carbon content should less than 50%, sulphur content less than 0.08%, and ash content less than 3%.

1. There are three coal feeding methods: hydraulic push, manual drive and chain drive.
2. Beautiful appearance: heat insulation material and high color board outer packing are adopted.Namely heat preservation and energy saving, and beautiful generous.
3. Simple operation: it can run for several hours at a time, and users can enjoy 24-hour heating as a power plant.
4. Energy-saving economy: reasonable structure, adiabatic combustion, high combustion efficiency, obvious energy saving, low fuel cost.
4. Saving investment: no investment of drum and induced draft fan, saving electricity cost, the products are fast installed and easy to install.
5. Environmental protection standards: the upper combustion mechanism design is adopted to meet the smoke emission standards of coal-fired boilers, which can be used in a class of environmental protection areas without disturbing the residents with noise.
Application for biomass steam boiler
wood fired steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.

Automatic control and fault protection of steam boiler
Boiler steam pressure automatic regulation system: boiler steam pressure automatic regulation system control system into the working state, in meeting the necessary conditions for combustion: when the steam pressure in the boiler is higher than or equal to the set pressure limit, the control system output stop signal.Until the induced draft fan is stopped.
Feed water automatic control: when the system is on duty and working normally, start the feed water pump, the water pump works, the water level differential pressure transmitter detects the water level signal, and keeps the water level of the pot stable.Ensure the quality of steam.The water level regulating instrument shows the boiler water level.
Manual control: The water pump can also be manually controlled by touching the key on the control panel.
Fault alarm and protection
The control system can monitor the current working conditions of the steam boiler in real time and carry out real-time and comprehensive intelligent fault identification and treatment.The control system can diagnose and deal with the following faults in real time:
Extremely high steam pressure protection: When the steam in the pot is overpressured, the control system will immediately enter the chain, and sound and light alarm will be given, and the screen will display "extremely high steam pressure".After the fault is eliminated, press the reset button to break the chain.
Protection of water shortage in boiler: in case of extremely low water level failure due to pump failure or other reasons, the control system will immediately shut down the power supply of induced draft fan, enter the chain, and alarm with sound and light, and the screen will show extremely low water level.After the fault is eliminated, press the reset button to break the chain.
Ultra high boiler water level: when the water level in the pot is higher than the upper warning level, sound and light alarm will be given.Prompt "ultra high limit of water level in the pot", the display screen prompt drainage.Automatic recovery after the fault is eliminated, stop the pump without stopping the furnace.
Water pump motor overload: heat relay action when water pump motor overflows, cut off the power supply of water pump motor and stop water pump, realized by hardware.
Power failure: In case of power failure, the control system will immediately shut down the power supply of all equipment in the cabinet.When the power is restored, the cabinet will be in the off-duty state automatically. It is necessary to restart the machine and start the equipment to ensure the safety of the equipment.
