  • Why don’t the pumps of coal-fired boilers absorb water? 2023-12-29
    If the pumps of a coal-fired boiler are not absorbing water, it could be due to several reasons. It's essential to diagnose the issue accurately for an effective solution. Here are some common causes: Air Locks in the Pump or Suction Line: If there is trapped air within the pump or the suction line, it can prevent the pump from creating the necessary vacuum to draw water. Low Water Level in the Feed Tank: If the water level in the feed tank is too low, the pump may not have enough water to dra...
  • Do biomass-fired boilers produce any smoke or other emissions? 2023-12-29
    Biomass-fired boilers are increasingly popular due to their renewable and sustainable fuel source. However, like any combustion process, biomass boilers do produce emissions, including smoke and other gases, which can have environmental and health impacts if not properly managed. What Are Biomass-Fired Boilers?Biomass boilers use organic materials, such as wood chips, pellets, or agricultural waste, as fuel to generate heat or electricity. They are considered more eco-friendly compared to fossi...
  • What if fire grates of the thermal oil heater are stuck? 2023-12-08
    Identify the Cause: Before attempting to fix the issue, it's important to understand why the grates are stuck. Common reasons include excessive ash accumulation, warped grates due to overheating, mechanical failures, or obstructions caused by foreign objects. Shut Down the Heater: For safety, turn off the heater before inspecting or repairing the grates. Ensure that all safety protocols are followed to prevent accidents. Inspect for Ash and Debris: Check the grates for any ash buildup or forei...
  • How to select heat medium oil for liquid phase heating systems? 2023-12-01
    Selecting the right heat medium oil (also known as thermal oil or heat transfer fluid) for liquid phase heating systems is crucial for efficient and safe operation. Here are key factors to consider when choosing a heat medium oil: Operating Temperature Range: Different oils have different operating temperature ranges. Choose an oil that can maintain stable thermal properties within the temperature range required by your system. Both the maximum and minimum operating temperatures are important t...
  • What causes the black smoke in gas-fired boilers? 2023-12-01
    Black smoke in gas-fired boilers is typically an indication of incomplete combustion, where the fuel is not being burned efficiently. This can happen due to several reasons: Poor Air-to-Fuel Ratio: The most common cause of black smoke is an improper balance between the air and fuel. Too much fuel or insufficient air leads to incomplete combustion, resulting in black smoke due to unburnt carbon particles. Dirty or Clogged Burners: Over time, burners can become dirty or clogged, affecting the ef...
  • Why gas-fired boiler chimney drops water? 2023-12-01
    If you notice water dripping from a gas-fired boiler's chimney, it could be due to condensation, which is a common issue in high-efficiency boilers. Here are some key reasons and explanations for this phenomenon: Condensation of Flue Gases: Modern high-efficiency gas boilers are designed to extract as much heat as possible from the combustion gases before they are expelled through the chimney. This process can cool the gases to a point where the moisture in them condenses into water. This is mo...
  • What if boiler cannot be ignited in the operation when the pressure is normal? 2023-12-01
    Question details (performance):Fail ignite, normal pressure, has electricity.Answer: Fault reason:1. The ignition transformer is burnt out.2. The high-voltage wire is damaged or detached.3. The clearance is too large or too small, and the relative size of the ignition rod position is wrong.4. Electrode rupture or grounded short circuit.5. Improper spacing. Troubleshooting:1. Replace with a new one.2. Reinstall or replace.3. Readjustment.
  • Why doesn't the gas-fired boiler ignite despite running burner motor and voltage at controller? 2023-11-24
    If the burner motor of a gas-fired boiler is running and voltage is present at the controller terminal, but there is no ignition followed by a system failure and stop, this situation can be attributed to several potential issues. Here's a breakdown of what might be happening and what to check: Ignition System Failure: The ignition system, which may include spark electrodes or an igniter, could be faulty. Check for any signs of damage, misalignment, or dirt on the igniter or electrodes. Control...
