Structural features:
YLW series biomass fuel fired organic heat carrier boilers are assembled forced circulation chain grate (reciprocating grate) boilers. The boiler consists of an upper body and a lower grate, which are assembled on site. The boiler has a compact structure, small floor area, high degree of assembly, short installation cycle, and low installation costs.
The radiant heating surface of the boiler body adopts single furnace bore or closely arranged double sided coil tubes, and the rear force serpentine convective heat exchange tubes.
According to the characteristics of the fuel, a special ash prevention structure is adopted to reduce ash deposition and facilitate ash removal. The convection heat exchange section of the boiler adopts high and low staggered arrangement, widens the spacing, and arranges soot blowing and cleaning devices to reduce ash accumulation in the boiler and improve boiler efficiency.
Compared with traditional coal-fired boilers, it has a larger furnace combustion space to adapt to the characteristics of high volatile biomass fuel.
The grate combustion chamber is heightened and secondary air is arranged: the grate is divided into silos for air intake, the air volume is independently regulated and managed, and the grate is continuously regulated.
The grate is made of high-temperature resistant material and is cooled by reasonable air distribution. The grate is reliable in use and has a long service life.
The feeding device has independent intellectual property rights and adopts a locking mechanism.
The radiation and convection heat exchange surfaces of the furnace adopt special wear resistant structures.
The boiler adopts high-quality thermal insulation materials and special construction technology, with good thermal insulation effect.
The butt joint of the boiler heating surface tube requires a fully automatic gas shielded welding process and equipment, which can be real-time X-ray online detection. The welding quality is stable and reliable.
Performance advantages:
1. Energy saving
The radiation heat exchange section of the furnace adopts a double densely arranged coil structure, and the convection heat exchange section has an S-type multiple return heat transfer.
The tail is equipped with an air preheater, a steam waste heat boiler, and a hot water economizer for waste heat recovery based on the user's residual heat usage, to reduce the exhaust gas temperature, improve boiler efficiency, reduce fuel consumption, and save energy.
The boiler adopts high-quality thermal insulation materials and special construction processes, with low heat dissipation loss, low exhaust gas temperature, and high thermal efficiency of the boiler.
The grate combustion chamber is heightened and arranged with combustion supporting secondary air to ensure uniform and sufficient fuel combustion and high combustion efficiency.
The grate and arch are specially designed, and the grate is divided into silos for air intake. The air volume is independently adjusted, resulting in a wide range of fuel adaptability.
The tail convection heat exchange section is designed with a special structure and equipped with a blowing device, which ensures no ash accumulation during operation and high heat exchange efficiency.
The layout of the heating surface is sufficient and reasonable, the boiler temperature rises and starts quickly, and the load margin is large.
2. Safe and reliable
The radiation heating surface of the furnace adopts closely arranged coils, with sufficient arrangement of heating surfaces, effectively reducing the heat load on the pipe surface, and making the use of heat transfer oil media safer.
The medium flow is reasonable, and the heat transfer oil ranges from low (inlet) to high (outlet). The medium gas generated during operation is difficult to stay in the furnace, which can be easily discharged from the system.
The feeding device adopts a locking mechanism and is equipped with a secondary air supply to effectively prevent the flame from backfiring and damaging the hopper.
The boiler operation adopts remote and near ground monitoring, with complete automatic control and monitoring instruments, safe and reliable, and easy to operate. Combining industrial automation control technology, Internet technology, computer software, and artificial intelligence technology, an Internet of Things platform for industrial boilers is established, which can achieve remote human-computer interaction and data sharing, and achieve automatic control.
3. Environmental protection: Configure appropriate flue gas treatment equipment according to local environmental protection requirements, and ensure that flue gas emissions meet environmental protection requirements..
