Utilities operating under stringent regulations need assurance that a circulating fluidized bed coal fired power plant will meet emissions and reliability targets from day one.
ZOZEN Boiler’s CFB solutions are engineered to comply with, and often surpass, tight limits on SO2, NOx, and particulate matter. The technology’s moderate combustion temperature and staged air inherently suppress thermal NOx, while in-furnace limestone injection captures sulfur before it reaches downstream eq...
ZOZEN Boiler reduces operating costs in a circulating fluidized bed coal fired power plant by optimizing fuel flexibility, improving thermal efficiency, and minimizing maintenance. The CFB’s ability to use low-cost, low-grade coals and alternative solids is amplified by ZOZEN’s furnace and cyclone design, which maintains complete combustion across variable fuels, reducing unburned carbon losses and slagging.
Enhanced heat transfer surfaces—economizers, air preheaters, and well...
ZOZEN Boiler delivers a comprehensive solution to raise efficiency and reduce emissions in a circulating fluidized bed coal fired power plant by combining robust engineering, advanced fluidization design, and smart control systems.
First, ZOZEN’s CFB technology optimizes the air–fuel–solid interaction through carefully designed furnace geometry, high-efficiency separators, and staged combustion, enabling long residence time and uniform temperature distribution. This uniformity...
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 designs its coal boilers for sale South Africa with a systems approach that boosts thermal efficiency and lowers total fuel consumption.
First, furnace aerodynamics are optimized via balanced primary, secondary, and tertiary air distribution, ensuring complete combustion across a wide range of South African coal qualities, including bituminous and certain washed coals. Chain grate and spreader-feeding systems are engineered for uniform fuel bed thickness and stable ignition, minimi...
The debate on banning coal focuses on balancing environmental goals and energy needs. At ZOZEN Boiler, we believe the solution lies in clean coal technologies rather than an outright ban.
1. Environmental ConcernsCoal combustion releases CO₂, SO₂, and particulates. To address this, ZOZEN integrates low-NOx combustion, multi-stage dust collection, and optional desulfurization into our industrial coal boilers, helping clients achieve sustainable production.
2. Industrial Energy DemandIn many reg...
A coal-fired boiler is designed to convert coal’s chemical energy into thermal energy, which produces steam or hot water for industrial processes. At ZOZEN Boiler, our coal-fired solutions integrate efficient combustion, optimized heat transfer, and advanced automation systems.
1. Combustion ProcessCoal is fed into the furnace using chain-grate stokers or circulating fluidized bed systems. Inside the furnace, coal undergoes drying, volatile release, and complete combustion. ZOZEN boilers ...
What Does "Heating Surface Area" Mean in a Boiler?The heating surface area of a boiler refers to the total area of the boiler’s surfaces that are exposed to heat for transferring energy to the water or steam. It directly impacts the boiler’s efficiency, steam production capacity, and overall performance.
For a 10 ton boiler, the heating surface area can vary depending on the boiler’s design, type, and manufacturer. Typically, fire tube boilers, such as ZOZEN’s WNS series...
