Question details (Performance):Dust collecting cloth bag damages a lot. Answer: The cause of the problem: As the biomass-fired boiler fuel moisture is high, and bag material is general PPS, which will reduce the base fabric of the bag in the case of high temperature, high humidity, hydrolysis, oxidation, and cause damage; In addition, the fuel moisture is high and it cannot be completely burned in the furnace, so it burns in the dust collector, which is also an important reason for the damage of the cloth bag.Troubleshooting:(1) Design by full consideration of high fuel moisture, choosing the appropriate induced draft fan, if the existing design is not enough then consider change the induced draft fan.(2) If induced air volume is sufficient, a proper distribution of the first and second wind should be considered. Generally, the fuel with high moisture and light quality such as wood chips, straw and wheat straw hood, the secondary air volume should be increased. For bark, miscellaneous
Question details (Specific performance):Biomass environmental protection and energy saving fuel made of straw and livestock etc., their combustion is not full. Answer: The cause of the problem:1. Air quantity is insufficient or too big.2. Outer flame position is not proper.Troubleshooting:1.Sufficient temperature： sufficient combustion of biomass boiler needs high temperature, combustion rate is proportional to the temperature, to raise the temperature as much as possible but guarantee there is no slagging.2. Proper air volume. If the air volume is too large, it will reduce the temperature of the furnace and increase the incomplete combustion of fuel. If the air volume is insufficient, the combustion efficiency will be reduced, and the waste of fuel will also increase the emission of smoke.3. Sufficient mixing of fuel and air. During the burning stage of biomass boilers, the sufficient mixing of air and fuel should be ensured and the disturbance should be strengthened during the burnin
