  • 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...
  • 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...
  • What causes the burner motor of the gas-fired boiler not running? 2023-11-24
    If the burner motor of a gas-fired boiler is not running, several issues could be at play. Diagnosing the problem involves checking various components and systems. Here are some common causes: Electrical Issues: Check if there's an electrical supply to the motor. A tripped circuit breaker, blown fuse, or loose wiring could interrupt power supply to the motor. Faulty Motor: The motor itself could be malfunctioning. Over time, motors can wear out or burn out due to electrical issues or mechanica...
  • What causes the combustion engine overheat during the operation of the gas-fired boiler? 2023-11-24
    Overheating in the combustion engine of a gas-fired boiler can be caused by several factors. Understanding and addressing these issues is crucial for maintaining the efficiency and longevity of the boiler, as well as for ensuring safety. Here are some common causes of overheating in the combustion engine of a gas-fired boiler: Insufficient Water Flow: If there isn't enough water flowing through the boiler, it can't absorb enough heat from the combustion process, leading to overheating. This cou...
  • Why doesn't the gas boiler's motor turn on after pressing the start button? 2023-11-24
    (Question details) specific performance:The gas boiler is powered on, press start, the motor does not turn. Answer: Fault reason:1. Insufficient pneumatic locking.2. The solenoid valve is not sealing, and there is air leakage at the joint. Check the lock.3. The thermal relay is open.4. At least one of the conditional circuits is not valid (water level, pressure, temperature and to check whether the program controller is energized to start). Troubleshooting:1. Adjust the air pressure to the requested value.2. Clean or repair solenoid valve pipe joint.3. Check whether the component is damaged and motor current by reset.4. Check whether the water level, pressure and temperature exceed the limit.ZOZEN gas-fired boiler adopts automatic control to control the operation, combustion, water level, temperature and steam pressure. In case of such problems, the system will automatically prompt the error code.
  • 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 to estimate thermal efficiency of gas fired boilers? 2023-06-09
    There are several ways to estimate the thermal efficiency of gas-fired boilers:   1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.   2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
