In the utilization of biomass energy, the stable and efficient operation of biomass reciprocating grate boilers is inseparable from meticulous maintenance. Hanyu Boiler, with its technology and experience, provides a professional guide.
Daily Inspections for the Foundation
The technical team of Hanyu Boiler emphasizes that daily inspections are the foundation for ensuring the normal operation of the boiler. Check the appearance of the boiler daily to see if there is any damage, deformation, or leakage. Pay special attention to the sealing of the furnace door and observation holes to prevent heat loss. At the same time, check whether the pipe connections are secure to ensure smooth media transportation.
Grate Maintenance as the Key Point
1. Ash and Slag Removal: Biomass fuels produce a large amount of ash and slag during combustion. If not cleaned promptly, it will block ventilation, affect combustion, and even clog the grate. Users should regularly clean the ash accumulated on the grate with tools such as scrapers and compressed – air spray guns according to the operating frequency, and promptly remove the slag to ensure the normal operation of the slag-discharging system.
2. Wear Inspection: Grate plates are prone to wear and deformation under high temperatures, mechanical movements, and fuel friction, especially cast-iron grate plates. When the wear exceeds the limit, they should be replaced promptly to avoid affecting combustion. At the same time, regularly check the wear and looseness of the grate transmission mechanism, such as chains, gears, and drive shafts, and lubricate them promptly to ensure smooth transmission.
Optimizing the Combustion System
1. Appropriate Fuel Selection: The quality of the fuel affects the operation of the boiler. Users should select fuels according to the boiler design, strictly carry out pretreatment, crush the fuel to an appropriate particle size, remove impurities, and control the moisture content within 15% – 20% to prevent equipment damage and improve combustion efficiency.
2. Precise Air Adjustment: Reasonable air volume is the key to full combustion. Although Hanyu Boiler has an automatic air – adjusting system, users still need to fine – tune according to the actual situation such as the color of the flame and flue – gas emissions. A golden – yellow and smokeless flame indicates an appropriate air volume; a red and smoky flame requires an increase in air volume; a violently flickering and white – colored flame means reducing the air volume.
Water Quality Management for Safety
1. Softening of Inlet Water: Boilers have high requirements for water quality. Hard water is likely to form scale, which affects heat transfer, increases energy consumption, and even causes potential safety hazards. Hanyu Boiler recommends installing water – softening equipment to reduce the content of calcium and magnesium ions in the water.
2. Regular Blowdown: Regular blowdown can discharge impurities and salts at the bottom of the boiler and maintain stable water quality. The blowdown frequency is determined according to the water quality and operating time, generally at least 1 – 2 times a week. Hanyu Boiler is oriented towards user needs and provides maintenance suggestions and after – sales services.
