There may be many reasons for the difficulty of replenishing water in biomass steam boilers, and here are the common causes and their solutions
The water level is too low when the boiler is started: When the boiler is started, the water level is too low, and the water pump filling speed is difficult to quickly meet the consumption demand. Therefore, it is important to make sure that the water level is in the proper position before starting the boiler. The water level can be confirmed by looking at the water level gauge. If the water level is too low, add water to the appropriate height before starting the boiler. This gives the pump enough time to meet the make-up demand.
Pump failure: The water pump is the core component of the boiler water supply system, if the water pump fails, such as motor damage, poor sealing and air intake, etc., it will lead to water replenishment difficulties. Regularly check the working condition of the pump to ensure that it is operating properly. If the pump is found to be faulty, it should be repaired or replaced in time.
Clogged pipeline: Due to debris or scale deposition in the water, it may cause the pipeline to become clogged and affect the normal flow of water. Regularly inspect the pipeline, and clean up the blockage in time. Chemical cleaning or physical cleaning can be used. Chemical cleaning can be carried out with specialized cleaning agents; Physical cleaning can be carried out by means of high-pressure water guns or mechanical cleaning equipment.
Failure of the water level gauge or water level sensor of the water tank or the boiler tube: Modern boilers generally use automatic water supply systems, and the failure of the water level gauge or sensor may cause the water replenishment system to not work properly, such as the inability to perceive low or high water levels, resulting in the water replenishment system not being able to automatically replenish water. Regularly check the status of the water level gauge and sensors to make sure they are working properly. If a fault is found, it should be repaired or replaced in a timely manner. For the water level gauge problem, you need to check whether it accurately shows the water level; For sensor problems, you need to check whether it is working properly, and if there is a problem, you need to replace the sensor.
Water quality problems: If the water quality used does not meet the requirements, such as containing a large number of impurities or too high hardness, it may lead to scaling of the pipeline, affecting the water intake and water replenishment effect. Ensure that the water used meets the requirements. The influent water is filtered and softened to reduce impurities and hardness.
The above are some common reasons, you can check by yourself, if you can't solve it, it is recommended to contact a professional to deal with it, so as to avoid affecting the safe operation of boiler equipment. Biomass boilers
