Product Overview
The Horizontal Tube Primary Gas Cooler features a vertical rectangular shell with cooling water tubes installed at a 30° angle to the horizontal plane. Coke oven gas flows from top to bottom, while cooling water is supplied from the bottom in multiple stages, achieving uniform and highly efficient cooling. Outlet gas temperature can be reduced to within 2°C above inlet water temperature.

Key Advantages

• High Heat Transfer Efficiency – Φ57×3 steel tubes with dense layout enhance turbulence and improve cooling performance

• Multi-Stage Water Supply – Flexible combination of chilled water, circulating water, and heating water

• Automatic Spray Cleaning – Ammonia water or condensate spray removes tar and naphthalene deposits

• Compact & Durable – Small footprint, stable operation, and low maintenance

Process Flow
Crude gas from the coke oven → Gas-liquid separator → Upper stage cooling with circulating water (to ~45°C) → Lower stage cooling with chilled water (to ~22°C) → Gas booster fan → Electrostatic tar precipitator → Desulfurization & sulfur recovery. Condensate, tar, and ammonia water are recycled or sold.

Applications
Coke oven gas recovery · Chemical industry · Energy-saving projects
