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:

There are two types of burners for industrial steam boilers, depending on how they control the mixture of air and fuel at the key point in the boiler's operation, which is the generation of combustion.
Mixing different fluids and subjecting them to high temperatures can have unpredictable results. In addition, once fluids have been mixed, the baseline analysis of the fluid is no longer applicable making it difficult to perform an annual analysis of the fluid for degradation.
The air oxygen content's effect on the boiler is mainly reflected by the effect on the blowing rate. Boiler will have typical phenomena if the blowing rate is high or low.
The heating load of an industrial boiler refers to the amount of energy required to generate a certain amount of heat in a specific period, usually measured in British Thermal Units (BTUs) per hour, kilowatts (kW), or megawatts (MW). Essentially, it's the amount of energy needed to heat the water or generate steam in the boiler for industrial processes or heating purposes.
Understanding the heating load is crucial for several reasons:
Boiler Sizing: Accurately determining the heating load is e...
A hybrid or combination boiler system refers to a heating system that combines two different types of heating technologies or fuels to optimize efficiency, performance, and cost-effectiveness. This system typically involves the integration of a traditional gas or oil boiler with a renewable energy source, such as a solar thermal system, a biomass boiler, or a heat pump. The idea is to harness the strengths of both systems to achieve greater energy efficiency and environmental sustainability.

Yes, there is typically a minimum flow requirement for a thermal oil heater, and it's a crucial factor for the safe and efficient operation of the system. Thermal oil heaters, also known as thermal fluid heaters, use a special heat transfer fluid in a closed loop system to transfer heat to a process or heating application. The minimum flow requirement is essential for several reasons:
Preventing Overheating: Ensuring a minimum flow rate is critical to prevent the thermal oil from overheating. I...
Biomass-fired boilers are increasingly popular due to their renewable and sustainable fuel source. However, like any combustion process, biomass boilers do produce emissions, including smoke and other gases, which can have environmental and health impacts if not properly managed.
What Are Biomass-Fired Boilers?Biomass boilers use organic materials, such as wood chips, pellets, or agricultural waste, as fuel to generate heat or electricity. They are considered more eco-friendly compared to fossi...
