Structural characteristics

• The YLW series biomass fuel organic heat carrier furnace is an assembled forced circulation chain grate (reciprocating grate) boiler. The boiler consists of an upper body and a lower grate, which are assembled on site. The boiler has a compact structure, small footprint, high assembly level, short installation cycle, and low installation cost.
• The radiation heating surface of the boiler body adopts a single furnace or closely arranged double-sided coil, and the rear force serpentine convection heat exchange tube.
• According to the characteristics of the fuel, a special anti ash structure is adopted to reduce ash accumulation and facilitate ash cleaning. The convective heat exchange section of the boiler adopts high and low staggered arrangement, widened spacing, and arranged with blowing and cleaning devices to reduce boiler ash accumulation and improve boiler efficiency.
• Compared with traditional coal-fired boilers, it has a larger furnace combustion space to adapt to the high volatility of biomass fuels.
• Raise the combustion chamber of the grate and arrange secondary air: the grate is divided into compartments for air intake, the air volume is independently adjusted, and the grate has stepless speed regulation.
• The grate adopts high-temperature resistant material grate and reasonable air distribution cooling form, which ensures reliable use and long service life of the grate.
• The feeding device has independent intellectual property rights and adopts a locking mechanism.
• The radiation heat transfer surface and convection heat transfer surface of the furnace adopt special wear-resistant structures.
• The boiler adopts high-quality insulation materials and special construction technology, with good insulation effect.
• The docking of boiler heating surface tubes requires fully automatic gas shielded welding technology and equipment, which can be 100% real-time X-ray online detection. The welding quality is stable and reliable.

Performance advantages

1. Efficient and energy-saving

• The radiation heat exchange section of the furnace adopts a double packed coil structure, and the convection heat exchange section adopts an S-shaped multi pass heat exchange.
• The tail end is equipped with air preheaters, steam waste heat boilers, and hot water energy-saving devices based on the user's residual heat usage for waste heat recovery, reducing exhaust gas temperature, improving boiler efficiency, reducing fuel consumption, and saving energy.
• The boiler adopts high-quality insulation materials and special construction technology, with less heat loss, low exhaust temperature, and high thermal efficiency of the boiler.
• Raise the grate combustion chamber and arrange secondary air for combustion assistance, ensuring uniform and sufficient fuel combustion with high combustion efficiency.
• The grate and arch are specially designed, and the grate is divided into compartments for air intake, with independent adjustment of air volume and wide fuel adaptability.
• The tail convective heat transfer section is designed with a special structure and equipped with a blowing device, which operates without accumulating dust and has high heat transfer efficiency.
• The layout of the heating surface is fully and reasonably arranged, the boiler heats up quickly, and the load margin is large.

2. Safe and reliable

• The radiation heating surface of the furnace adopts closely packed coil pipes, with sufficient arrangement of heating surfaces, effectively reducing the surface heat load of the pipes, and making the use of heat transfer oil medium safer.
• The medium flow is reasonable, and the heat transfer oil is from low (inlet) to high (outlet). The medium gas generated during operation is difficult to stay in the furnace and can be easily discharged from the system.
• The feeding device adopts a locking mechanism and supplies secondary air to effectively prevent the hopper from being damaged by flame backfire.
• The boiler operation adopts remote and near ground monitoring, with complete automatic control and monitoring instruments, safe and reliable, and easy operation. Combining industrial automation control technology, Internet technology, computer software and artificial intelligence technology, the Internet of Things platform for industrial boilers can be established, which can realize remote human-computer interaction and data sharing, and realize automatic control.

3. According to local environmental protection requirements, appropriate flue gas treatment equipment is equipped, and flue gas emissions meet environmental protection requirements..
