Performance characteristics:
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.

Fault alarm and safety protection
The control system can monitor the current working condition of the steam boiler in real time, and carry out real time and comprehensive intelligent fault identification and processing.The control system can diagnose and deal with the following faults in real time:
High steam pressure protection: when the steam overpressure in the pot, the control system immediately enters the chain, and the sound and light alarm, the screen shows "high steam pressure".After the fault is eliminated, press the reset key to remove the chain.
Water shortage protection in the boiler: when the water level of the boiler is extremely low due to the pump failure or other reasons, the control system will immediately turn off the power supply of the induced draft fan and enter the chain, and the sound and light alarm will be given, and the screen will show the water level is extremely low.After the fault is eliminated, press the reset key to remove the chain.
Boiler water level is too high: when the water level in the boiler is higher than the upper warning level, the sound and light alarm will be given."Ultra-high water level in the pot" prompts, and the display prompts drainage.Automatic recovery after fault elimination, stop the pump and keep the furnace.
Pump motor overload: heat relay action when the pump motor overflows, cut off the power supply of the pump motor and stop the pump, which is realized by hardware.
Power failure: when power failure occurs, the control system will immediately turn off the power of all equipment in the cabinet where the power failure occurs.When the power is restored, the cabinet will automatically be off duty. It is necessary to restart the machine and start all the devices to ensure the safety of the equipment.
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.
