Modular Captive Power Plants (2MW – 20MW+)

Secure reliable, 24/7 baseload power independent of the grid. Our containerized coal gasification systems deploy in 7-10 days, turning low-cost local coal into high-value electricity.

CORE ADVANTAGES: SMART DESIGN & TECHNOLOGY

PART A: Smart Modular Design & Economy

  • SMART MODULAR DESIGN: Containerized components, globally accessible for marine/land transportation. Support on-demand capacity expansion (500kW to 2000kW modules).
  • SMART ECONOMY: Quick installation (7-10 days), Low investment, Less water consumption. Automatic control reduces labor costs.
  • SMART INSTALLATION: Frame design facilitates simple loading. Minimized on-site civil construction (no factory building needed).

PART B: Advantages Compared with Conventional Two-stage Gasifiers

  • Zero Waste Emission: Featuring a refined process design with a specialized Tar and Phenolic Water Incineration Unit, ensuring environmentally friendly operation.
  • In-depth Purification: Unlike standard models, our system is equipped with Two ESP (Electrostatic Precipitator) purification systems to guarantee ultra-clean syngas output.
  • Whole-system Synergy: High compatibility design for reliable Gas-to-Power Conversion. Engineered for low-speed power plants (600 RPM) to ensure a 20+ Years Lifespan.

Broad Feedstock Adaptability: Anthracite, Bituminous & Lignite

Our advanced gasification system is engineered to process specific coal ranks, ensuring stable syngas production from high-grade anthracite to low-grade lignite.

Low-Rank & High-Volatile Coals

Including Bituminous Coal, Sub-bituminous Coal, Lignite / Brown Coal, and High-Ash Coal (Ash Content >30%).

High-Rank Solid Fuels (High Carbon)

Suitable for high-efficiency gasification requiring stable heat value, including Anthracite Coal (White Coal), Metallurgical Coke, and Semi-Coke (Blue Carbon).

Biomass & Alternative Fuels

Renewable options for co-gasification or specific blending ratios, including Wood Chips/Briquettes, Palm Kernel Shells (PKS), and Agricultural Residue (Rice Husk, Straw).

The Economics: Diesel vs. Coalwatt®

The Diesel Problem

Fuel Cost: High ($1,000+ / ton)

Cost Per kWh: $0.30 - $0.45 / kWh

Risk: High price volatility and theft risk.

The Coalwatt Solution

Fuel Cost: Low ($50 - $150 / ton)

Cost Per kWh: $0.06 - $0.10 / kWh

Savings: Save ~$1.5M per year (per 1MW unit)

Result: Payback Period in 18 - 36 Months.

Maximize Revenue: One Fuel, Three Value Streams

Stream A: Electricity

Replace expensive grid power or diesel.

Value: Save $0.20+ per kWh.

Stream B: CHP

Recover waste heat from engine exhaust to produce Steam or Hot Water.

Value: Efficiency increases to >85%. Free heat for drying or processing.

Stream C: Ash & Cinder

Gasifier bottom ash is a perfect raw material for Construction Bricks.

Value: Turns waste disposal cost into a revenue stream.

From Coal to Clean Power: The 4-Stage Process

Direct conversion of Raw Coal into Clean Syngas and Baseload Electricity via an automated, enclosed system.

Diagram of 4-Stage Coal Gasification Power Generation Process

1. Automated Feeding

Raw coal is automatically fed via airtight double-lock valves to maintain negative pressure and prevent gas leakage.

2. Gasification

Inside the reactor, high‑temperature pyrolysis and reduction (≥1000 °C) transform solid fuel into combustible syngas (CO + H₂).

3. Purification

The raw gas passes through cyclone dedusters and wet scrubbers to rigorously remove dust, tars, and sulfur impurities.

4. Power Generation

Clean, dry syngas is fed into heavy-duty gas engines to generate continuous, grid-synchronized electricity.
