  • 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...
  • What causes the serious coal leakages of fire grate of coal-fired boilers? 2023-12-29
    Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes: Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall. Improper Grat...
  • 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...
  • What is the effect of volatile matter on boiler combustion? 2023-08-11
    Volatile matter in fuel, particularly in solid fuels like coal or biomass, plays a crucial role in the combustion process within boilers. Understanding the effect of volatile matter can help optimize the boiler operation for better efficiency and emissions. Here are the impacts of volatile matter on boiler combustion: Ignition and Combustion Stability: High volatile matter content aids in the easy ignition of the fuel. As volatile components release and ignite rapidly when the fuel is heated, t...
  • How should environmentally friendly coal-fired boilers be modified? 2023-07-21
    Coal-fired boilers can be made more environmentally friendly through various methods:   1. Retrofitting with Emissions Controls: These can significantly reduce pollutants. Examples include scrubbers that remove sulfur dioxide, selective catalytic reduction systems that remove nitrogen oxides, and fabric filters or electrostatic precipitators that remove particulate matter.   2. Efficiency Improvements: Upgrading the boiler's heat exchange systems can increase the amount of energy t...
