How a Coal-Fired Boiler Works – ZOZEN Technical Overview
22 Aug 2025
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 Combustion
Coal 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 Output
High-temperature gases pass through superheaters, economizers, and air preheaters. These stages improve thermal efficiency, ensuring a reliable supply of steam for diverse industries such as textiles, paper, and power generation.
3. Emission Reduction Technologies
ZOZEN integrates low-NOx burner designs, multi-layer dust collectors, and optional desulfurization units. These features help enterprises meet strict international environmental standards.
ZOZEN Boiler Recommendation
ZOZEN’s industrial coal-fired boilers are trusted by clients worldwide for their efficiency, safety, and eco-friendliness, making them ideal for heavy-duty steam generation.
