ZOZEN Boiler equips its coal boilers for sale South Africa with a complete suite of emission control technologies tailored to South African environmental standards and plant-specific targets. Primary measures start inside the furnace: optimized air staging, low-NOx burner arrangements, and precise grate-speed control promote complete combustion and suppress thermal NOx formation.
To address particulate matter, ZOZEN integrates high-efficiency dust collection systems—either baghouse filter...
ZOZEN Boiler provides a comprehensive range of coal boilers for sale South Africa to match diverse industrial needs, fuel qualities, and emission targets. Our portfolio includes SZL series chain grate coal-fired steam and hot-water boilers, engineered for high reliability and flexible load demands. The SZL design features a packaged or quick-assembly layout with a double-drum, water-tube structure for rapid steam generation, stable combustion, and simplified installation.

A coal-fired boiler functions by burning coal to generate heat, which converts water into steam. ZOZEN Boiler specializes in designing advanced systems with optimized combustion and intelligent controls for maximum efficiency.
1. Fuel System and CombustionCoal is delivered to the furnace via chain-grate stoker systems or fluidized bed combustors. ZOZEN boilers ensure precise air-fuel ratio control, enabling complete combustion and reducing fuel waste.
2. Heat Recovery and Steam OutputHigh-temp...
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.
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:

In the realm of industrial boilers, economizers play a pivotal role in enhancing efficiency and reducing fuel consumption. Essentially, a boiler economizer captures waste heat from boiler flue gases and uses it to preheat the feedwater before it enters the boiler. This process significantly improves the overall efficiency of the boiler system by reducing the need for the boiler to heat the water from a lower temperature. But, how long can one expect an economizer to last?
Lifespan of Boiler Eco...
(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
