  • What is the requirement of the control system of a coal-fired steam boiler ? 2020-05-15
    The coal-fired steam boiler is a forced circulation high-pressure single-tube DC boiler. Its operation process includes three processes: the combustion process of the fuel, the heat transfer process of flue gas to water and the vaporization process after water absorbs heat. In order to better control these different processes, the control system should make the heat of pulverized coal combustion adapt to the requirements of steam load changes and dryness.
  • Water for the boiler 2020-01-31
    A steam boiler plant must operate safely, with maximum combustion and heat transfer efficiency. To help achieve this and a long, low-maintenance life, the boiler water can be chemically treated. The operating objectives for steam boiler plant include: Safe operation. Maximum combustion and heat transfer efficiency. Minimum maintenance. Long working life. The quality of the water used to produce the steam in the boiler will have a profound effect on meeting these objectives.
  • What is the combustion efficiency of an industrial boiler? 2020-01-24
    Combustion efficiency is an indication of the burner’s ability to burn fuel. The amount of unburned fuel and excess air in the exhaust are used to assess a burner’s combustion efficiency. Burners resulting in low levels of unburned fuel while operating at low excess air levels are considered efficient. Well designed conventional burners firing gaseous and liquid fuels operate at excess air levels of 15% and result in negligible unburned fuel. Well designed ultra low emissions burners operate at a higher excess air level of 25% in order to reduce emissions to very low levels. By operating at the minimum excess air requirement, less heat from the combustion process is being used to heat excess combustion air, which increases the energy available for the load. Combustion efficiency is not the same for all fuels and, generally, gaseous and liquid fuels burn more efficiently than solid fuels.
  • What are the certain things about gas fired boiler that must obtain specific consideration? 2019-11-08
    Gas fired boiler is a boiler which uses gas as its fuel. Gas fired boiler consists of some important components such as flame ignition, gas metering system, air compressor, air piping, gas piping, burner nozzles, and the others. Combustion process of gas fired boiler should be maintained and operated properly to produce efficient combustion result.
  • 5 common problems with industrial boilers 2019-09-27
    Here are some common issues that could cause your industrial boiler to misbehave. 1. Burner Not Functioning Correctly. If the boiler burner fails or is faulty, then your boiler is not going to be able to generate heat efficiently, or in the worst case not at all . As industrial boilers are in almost constant use they are built to be very robust and last for decades, nevertheless they can still have problems with broken burners from time to time. Burner pumps, heads and nozzles can all cause problems but a swift replacement should limit your down time.
  • 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.
  • What are NOx emissions standards? 2019-09-06
    Nitrogen Oxides, commonly referred to as NOx, is a family of poisonous gases. These gases are best known for their role in air pollution, leading to occurrences of acid rain, smog, and the deterioration of the ozone layer.In short, NOx is harmful to the atmosphere and the environment and needs to be limited as much as possible.The problem is that NOx is quite common. It's created as a result of fuel burning at high temperatures. Cars, trucks, boats, and other kinds of vehicles emit NOx almost co...
  • How to recognize noise signals for your boiler and what to do to prevent potential disasters when the noise occurs? 2019-08-16
    Any unusual noises should always be treated seriously. One of the first things to check if a boiler is unusually noisy is the boiler's thermostat. If the thermostat is malfunctioning, water can become too hot and begin to boil, which could cause loud noises. If the thermostat is broken it may need to be replaced to prevent the water from heating up so much. Another reason for a noisy boiler could be mineral deposits. As the water heats up inside the boiler, minerals may sink to the bottom of the tank and affect the heat exchange. This may create hot spots within the boiler in which water is overheated, leading to loud noises. Low water pressure is also a concern that can result in loud noises. If water pressure is low, the boiler is tend to be overheat.
