  • How should the secondary air position of the circulating fluidized bed boiler be determined? 2023-09-29
    The position of secondary air in a circulating fluidized bed (CFB) boiler plays a crucial role in ensuring proper combustion, reducing emissions, and optimizing fuel efficiency. Determining the appropriate position for secondary air injection requires understanding the fundamental principles of fluidized bed combustion and addressing specific requirements based on the design and operation of the particular boiler. Here's a guideline on how to determine the secondary air position: ZOZEN circul...
  • What are the steps for furnace drying in a circulating fluidized bed boiler? 2023-09-22
    Furnace drying, often also called "oven drying" or "boiler drying-out", is an essential step when commissioning a new circulating fluidized bed (CFB) boiler or after any maintenance that might have introduced moisture into the system. The purpose is to remove moisture, ensure the refractory and insulation materials are dry, and prepare the system for safe ignition and operation.   Here are the general steps involved in furnace drying for a circulating fluidized bed boiler: Inspection: Be...
  • What do the internal circulation and external circulation of fluidized bed boiler mean? 2022-11-18
    Circulating fluidized bed boiler adopts fluidized combustion mode, which is especially suitable for inferior coal fuel and biomass bulk materials. The process of circulating fluidized bed boiler includes internal circulation and external circulation, which is the basic technical point of the boiler. What do the internal circulation and external circulation of circulating fluidized bed boiler mean?   Internal circulation and external circulation of fluidized bed boiler The internal circul...
  • What is the NOx emission standard of boiler? 2022-07-16
    Industry boiler is an important thermal power device, but the production of boiler NOx is the main component of environmental pollution, which not only causes acid rain but also destroys the ozone layer, and it is the key point of monitoring the products after boiler combustion. Here, ZOZEN Boiler will analyze the source and control method of boiler NOx for everyone.   Principle of NOx generation in boiler Ultimately, the nitrogen source of boiler NOx is nothing more than fuel or air, so...
  • What is the function of a separator in the CFB boiler? 2022-05-06
    Circulating fluidized bed boiler (CFB) is a fluidized combustion boiler. Its main structure includes combustion chamber and circulating furnace. It has many advantages such as high thermal efficiency and low pollution, and is especially suitable for inferior coal. During use, all parts of the boiler are playing their respective roles. Here, we will focus on the function of the separator of circulating fluidized bed boiler.   The working principle of circulating fluidized bed boiler separa...
  • How to improve the CFB boiler efficiency? 2021-09-17
    The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
  • What are the advantages of the CFB boilers? 2021-09-10
    As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
  • What does CFBC stand for? 2021-07-02
    When we talk about CFBC in the area of industrial boiler, it usually means the circulating fluidized bed combustion. The circulating fluidized bed (CFB) is a type of fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion.
