What Is a Coal Gasifier?
A coal gasifier is an advanced industrial system that transforms coal into syngas—a mixture of carbon monoxide, hydrogen, methane, and other gases—through a thermochemical process called gasification. Conducted in a low-oxygen environment, gasification avoids full combustion, producing a fuel gas suitable for furnaces, turbines, or chemical feedstocks. This technology offers a cleaner, more efficient alternative to burning coal directly, reducing emissions and enhancing energy utilization.
Yinuo’s coal gasifiers are engineered for versatility, available in single-stage and two-stage models. Single-stage gasifiers produce a basic syngas for simpler heating applications, while two-stage gasifiers deliver cleaner, higher-quality gas for precision processes. Designs include fixed-bed, fluidized-bed, and entrained-flow systems, each suited to specific coal types and production scales. Fixed-bed gasifiers are ideal for small-scale operations with coarse coal, fluidized-bed systems handle finer particles, and entrained-flow gasifiers support large-scale, high-temperature applications. Integrated gas cleaning removes tar, sulfur, and ash, ensuring reliable performance. Learn more about our systems at Our Gasifier Products.
How Coal Gasifiers Work
Coal gasification occurs at 800–1500°C, where coal reacts with oxygen, steam, or carbon dioxide in a controlled environment. The process involves four stages: drying, pyrolysis, gasification, and char reaction. Drying removes moisture, pyrolysis releases volatile compounds, gasification converts carbon to syngas, and char reactions generate additional gas and heat. The resulting syngas is purified using filters, scrubbers, or catalytic converters before use.
Yinuo’s gasifiers employ sophisticated controls for efficiency. Distributed Control Systems (DCS) regulate temperature, pressure, and gas composition, while real-time sensors ensure optimal operation. Fixed-bed gasifiers feed coal from the top, with syngas exiting below, suitable for small plants. Fluidized-bed gasifiers suspend coal in a gas stream for faster reactions, while entrained-flow gasifiers inject pulverized coal for high-capacity production. Heat recovery systems, like those in our Regenerative Burner Technology Guide, capture waste heat, boosting efficiency. Maintenance, such as reactor cleaning and sensor checks, sustains performance.

Types of Coal Gasifiers
Coal gasifiers are categorized by design, coal feed, and application:
Fixed-Bed Gasifiers
Coal is fed from the top, reacting with oxygen or steam at the base. Simple and cost-effective, they suit small-scale heating or power with coarse coal.
Fluidized-Bed Gasifiers
Coal particles are fluidized in a gas stream, enhancing reaction rates. Flexible for finer coal, they’re ideal for chemical synthesis or medium-scale power.
Entrained-Flow Gasifiers
Pulverized coal is injected with oxygen at 1400–1500°C, producing high-quality syngas for large-scale steel or chemical plants.
Single-Stage Gasifiers
These produce basic syngas with minimal processing, suitable for small furnaces or boilers, balancing cost and efficiency.
Two-Stage Gasifiers
Featuring dual reaction zones, they yield cleaner syngas with reduced tar, perfect for precision applications, per our Coal Gasification Technology Guide.
Integrated Gasification Combined Cycle (IGCC)
IGCC systems pair gasifiers with turbines for power generation, maximizing efficiency and reducing emissions.
