  • What impact will fuel have on boiler performance? 2024-01-26
    The impact of fuel on boiler performance is significant and multifaceted, affecting everything from efficiency and operating costs to maintenance requirements and environmental emissions. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the critical role that fuel quality and type play in the operational efficacy, longevity, and sustainability of boiler systems. Here's an overview of how fuel impacts boiler performance: 1. Efficiency and Heat ValueThe type and quality o...
  • 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 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...
  • What are the advantages of boiler fueled by the methanol? 2021-09-03
    The advantages of boiler fueled by the methanol can be concluded as follows: a. The emission from boiler fueled by the methanol is very environmentally friendly, without sulfur, particulate matter, heavy metals and polycyclic aromatic hydrocarbons.   b. The methanol fuel is quite cost-effective.   c. The operation of boiler fueled by the methanol is safety. Compared with compressed natural gas, liquefied petroleum gas, gasoline and diesel fuel, methanol has the char...
  • Why should oil be atomized prior to the oil combustion of oil-fired boilers? 2020-02-21
    The oil and air must be mixed for the combustion of the fuel droplets to take place. The combustion speed depends on the evaporation speed of oil droplets and the mixing speed of oil and air. The evaporation speed of oil droplets is related to the diameter and temperature of oil droplets. The smaller the fuel droplets, the higher the temperature and the faster the evaporation. On the other hand, it is conducive to mixing and combustion. The smaller the fuel droplets, the larger the air contract surface. Therefore, the fuel oil must be atomized before combustion. And, the oil can be heated and evaporated rapidly and fully burnt after it is injected to the furnace.
  • What is the boiler efficiency of an industrial boiler? 2020-01-24
    The term “boiler efficiency” is often substituted for thermal efficiency or fuel-to-steam efficiency. When the term “boiler efficiency” is used, it is important to know which type of efficiency is being represented. Why? Because thermal efficiency, which does not account for radiation and convection losses, is not an indication of the true boiler efficiency. Fuelto-steam efficiency, which does account for radiation and convection losses, is a true indication of overall boiler efficiency. The term “boiler efficiency” should be defined by the boiler manufacturer before it is used in any economic evaluation.
  • What is a dryback boiler and how does it compare to a wetback boiler? 2019-09-12
    A dryback boiler has a rear wall that is lined with refractory, a wetback boiler has a rear wall that is jacketed by water. Because of this fact, wetback boilers typically boast higher efficiency than dryback boilers as the heat from combustion goes directly into heating water instead of refractory. Wetback boilers are also more forgiving with load changes as the reversal chamber of the boiler is totally submerged in water creating an even heat transfer on the intermediate tube sheet to furnace joint.
  • How often should steam boilers be replaced? 2019-09-06
    The service life of your industrial boiler is 15 years. Of course, there are a number of factors that may force you to replace your boiler before it reaches the 15-year mark. If there are obvious signs of wear and tear, you may not want to push the boiler much longer.
