Best Sale Easy Operation Fixed Grate Industrial Biomass Wood Fired Steam Boiler for rice mill
DZH type steam boiler is a kind of horizontal three return water - fire tube boiler.Rows of water wall tubes are arranged on the left and right sides of the furnace, and two groups of tubes are arranged in the drum to form two return trips. The heating surface of this type of boiler is sufficient and the economizer of the heating surface at the end is equipped., and equipped with drum, induced draft fan to achieve mechanical ventilation.Layered combustion.The coal has wide adaptability and good smoke elimination effect.Equipping with high efficiency cyclone dust collector, the concentration of smoke and dust discharge can meet the environmental protection requirements of the second class area.The smoke passes through the upper combustion chamber of the rear arch, from the combustion chamber upward through the rear shed tube smoke chamber into the first tube bundle to the front smoke box, and then from the front smoke box into the second bundle to the rear smoke box, through the induced draft fan pumping into the flue, dust collector and chimney, and finally discharged to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Complete supporting auxiliaries.
This biomass steam boiler has high automation level, automatic adjustment of boiler feed water, high and low water level alarm, low water level interlock protection, and interlocking protection of lead and blower. Auxiliary auxiliary equipment is complete.
1. The biomass fired boiler is a horizontal fast-installed steam boiler with natural circulation of working fluid. The steam boiler heat exchange system consists of a drum, left and right headers, and water walls. The main heating surface has a water wall in the furnace, and part of the drum and the drum have convection. Tube bundle. This series of steam boilers are composed of five parts when they leave the factory: the main body of the boiler, the flue duct, the dust collector, and the piping system. The first four parts have been manufactured in the factory and can be transported to the installation site for assembly, which can be greatly shortened Installation cycle, and can guarantee the quality of product installation.
2. High-quality boiler design performance: The main heating surface of the steam boiler is made of seamless steel pipes for 20# low and medium pressure boilers, and the drum is made of special steel plates for the boiler. The left and right headers are made of seamless steel pipes.
3. The steam boiler arch is made of refractory concrete. The back arch is low and long, so it burns well. The two-wing flue and side wall bricks are made of refractory sintered bricks. The front and back walls of the boiler are made of general-purpose refractory bricks.
4. The wood steam boiler grate has reasonable air distribution, large combustion chamber, and strong applicability of coal types. It is suitable for all kinds of bituminous coal, anthracite, and mixed coal. It burns fully. Because the high-temperature flue gas enters the settling chamber, it enters the two-wing flue from both sides, The front smoke box, so the smoke and dust removal effect is good.
5. The water cycle is simple, and the structure of the pressurized parts is reasonable, and it is completely safe to operate under the condition of ensuring water quality.
6. The boiler combustion equipment is a quick-installed grate. The combustion equipment is manufactured and installed in the factory and can be directly installed on the foundation after being transported to the construction site. It has a reasonable and compact structure and low steel consumption, which makes the performance, weight and structure of the boiler Compared with domestic boilers of the same capacity, the size has obvious advantages.

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.
DZH series fixed grate biomass steam boiler is widely used in hospitals, schools, textile mills, garment factories, large supermarkets, garment factories, dyeing factory, hotel, dining room, restaurant, food factory, beverage factory, soy products, meat products factory, cannery, brewery, pharmaceutical factory, packaging plant, building materials factory, paint factory, swimming pool and other places of the enterprises and institutions.
