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.

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:

Testing a boiler's energy efficiency is essential for identifying how well it converts fuel into heat and for determining potential areas for improvement. As a professional industrial boiler manufacturer, ZOZEN Boiler emphasizes the importance of regular efficiency assessments to optimize performance, reduce fuel consumption, and minimize environmental impact. Here's a comprehensive approach to testing your boiler's energy efficiency:
1. Understand Key Efficiency RatingsAnnual Fuel Utilization ...
Conduction oil, commonly known as hot oil or heat transfer fluid, is an integral component in a broad range of industrial applications that require the transfer of thermal energy. This specialized fluid functions as an intermediary that carries heat from one point to another within a closed-loop system, ensuring the even distribution of heat across various machinery and equipment. Often, these oils are utilized in industries such as chemical processing, petrochemical plants, and manufacturing to...
Typically, a steam boiler should receive servicing at least once per year. Any kind of safety failure with a boiler can have serious consequences, and so a yearly inspection will help to spot any safety issues that need to be addressed. Servicing your boiler on a regular basis can also help you to save money on repairs. If you spot a problem during routine maintenance, there's a good chance you'll be able to fix it at a much cheaper cost than if the problem goes unnoticed and becomes a larger and more serious issue.
Load tracking is an important feature of industrial boilers that helps to optimize their performance and efficiency. Load tracking refers to the ability of a boiler to adjust its output in response to changes in demand.
In an industrial setting, the demand for steam or hot water can vary significantly depending on factors such as production schedules, weather conditions, and other variables. Load tracking allows the boiler to adjust its output to match the changing demand, ensuring that...
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 ...
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...
