  • What are the shutdown steps for the coal-fired steam boiler? 2023-04-27
    Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler: 1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components. 2. Shut off the fuel supply: The fuel supply to the boiler should be ...
  • What if biomass-fired boiler furnace wall cracks, deformation, coking, and tilt, loose bricks, tube wall was totally stuck and rock wool sealing is burned out & combustion chamber wall is damaged? 2023-04-27
    A biomass-fired boiler furnace that has multiple issues such as wall cracks, deformation, coking, and tilt, loose bricks, tube wall blockage, burned-out rock wool sealing, and combustion chamber wall damage requires immediate attention to prevent further damage and potential safety hazards.   Firstly, it is recommended to shut down the boiler immediately to prevent any further damage and ensure the safety of the surrounding area. The boiler should not be restarted until all necessary repa...
  • What measures are taken to eliminate the noise of industrial steam boiler? 2023-04-26
    Industrial steam boilers can produce noise for several reasons, including: 1. Combustion noise: Combustion noise is caused by the sound of the flames as they burn the fuel. This noise is typically louder during startup and shutdown, and can be reduced by optimizing the combustion process. 2. Boiler fan noise: Boiler fans are used to supply combustion air and to exhaust flue gases. The noise generated by the boiler fan can be reduced by installing a silencer or adjusting the fan speed. 3. Wate...
  • How Boiler Economizers Work? 2023-03-29
    Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations. How Do Boiler Economizers Work? A boiler economizer is essentially a heat exchanger that recovers w...
  • What is the function of the rear arch for coal fired boilers? 2023-03-20
    When it comes to coal fired boilers, the rear arch plays a critical role in the combustion process. The main function of the rear arch is to keep the fuel particles in suspension and prevent them from falling into the ash hopper, which can lead to incomplete combustion and decreased efficiency.   At ZOZEN, we understand the importance of a well-designed rear arch for coal fired boilers. That's why our coal fired boilers are equipped with advanced rear arch designs that enhance the combust...
  • What is the coal consumption of one set of 10tph coal-fired steam boiler? 2023-01-28
    The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
  • Why is the chain grate stuck and stopped during the operation of coal-fired boilers? 2023-01-28
    Question details (Performance) : 1. The vibrating coal grate stops running totally or intermittently. 2. The current of vibrating coal grate motor rises abnormally. 3. The safety clutch of transmission machine of grate or safety pin is broken.   Answer: cause of the problem: Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
  • 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...
