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.
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:
Common Causes & ZOZEN Solutions:Water Hammer (Steam Condensation Shock):

The load control is quite significant in boiler’s operation. Both overloaded and ultra-low loaded operations have negative effects on boiler. Different types of boiler have different rated load ranges, but ultra-low loaded operation’s harm to different types of boiler is similar.
Selecting a biomass-fired boiler for industrial applications involves careful consideration of various parameters to ensure efficiency, sustainability, and cost-effectiveness. Biomass boilers offer an eco-friendly alternative to fossil fuel-based boilers by utilizing renewable resources like wood chips, pellets, and agricultural waste. When choosing a biomass-fired boiler, pay attention to the following parameters:
1. Fuel Type and Availability:
Type of Biomass: The type of biomass fuel availa...

If the pumps of a coal-fired boiler are not absorbing water, it could be due to several reasons. It's essential to diagnose the issue accurately for an effective solution. Here are some common causes:
Air Locks in the Pump or Suction Line: If there is trapped air within the pump or the suction line, it can prevent the pump from creating the necessary vacuum to draw water.
Low Water Level in the Feed Tank: If the water level in the feed tank is too low, the pump may not have enough water to dra...
If you notice water dripping from a gas-fired boiler's chimney, it could be due to condensation, which is a common issue in high-efficiency boilers. Here are some key reasons and explanations for this phenomenon:
Condensation of Flue Gases: Modern high-efficiency gas boilers are designed to extract as much heat as possible from the combustion gases before they are expelled through the chimney. This process can cool the gases to a point where the moisture in them condenses into water. This is mo...
