For enterprise users considering gas boilers, a thorough understanding of gas boiler structure and working principle aids in scientific selection and efficient operation. This article systematically introduces gas boiler structure and working principle using ZOZEN Boiler’s WNS ...
  • What factors have influence on the service life of thermal oil heater? 2025-05-30
    Every customer is concerned about the service life of products he purchases. Extending the service life of thermal oil heater is helpful for reducing customer’s costs and increasing profits. Different existing thermal oil heaters on the market have different service years.
  • What are the basic configurations of the thermal oil heater system? 2025-05-30
    According to the differences in fuel and structure, industrial thermal oil heaters are mainly divided into the oil/gas-fired thermal oil heater and coal/biomass-fired thermal oil heater. The basic configurations of the thermal oil boiler system generally are as follows.
  • How to ensure the water quality of steam boiler? 2025-05-30
    Water treatment outside the boiler Before entering the boiler, raw water is treated with water treatment equipment to remove impurities such as hardness, salinity, dissolved oxygen, etc., so that the feed water can meet the water quality requirements specified by steam boiler. Common water treatment equipment includes sodium ion exchange water softening equipment, ion exchange desalination equipment, reverse osmosis water purification equipment and thermal oxygen removal equipment.   ...
  • What are the common faults and treatment methods of gas-fired thermal oil heaters? 2025-05-23
    There are mainly two kinds of faults of gas-fired thermal oil heaters: ignition failure and boiler inoperation.
  • What water should be used to produce the steam in the boiler? 2025-05-23
    The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
  • What are the requirements for the coal-fired boiler used in the food industry? 2025-05-23
    The food processing needs the steam or hot water to assist the production and improve the efficiency. Usually, the food plant needs the small tonnage boiler, so the coal-fired boiler is not recommended.
  • Why are there percussive sounds and vibrations in the boiler drum or pipe of a coal-fired boiler? (water impact) 2025-05-09
    Percussive sounds ("banging," "hammering," or "knocking") and vibrations in boiler drums or pipes are serious operational anomalies that demand immediate attention. At ZOZEN, we engineer our coal-fired boilers (like the SZL water-tube and DZL fire-tube series) to minimize these risks, but they can still arise due to operational or system issues. Here are the primary causes and ZOZEN's approach to mitigation: Common Causes & ZOZEN Solutions:Water Hammer (Steam Condensation Shock): Cause: Ra...
