Features

Energy Recovery & Cost Reduction

Utilizes waste heat from flue gases and industrial processes Converts thermal energy into usable hot water Reduces reliance on fossil fuels Lowers overall energy and operating costs Enhances total plant efficiency

Hydrogen‑Ready Operation

Suitable for up to 100% hydrogen combustion (with appropriate burner) Enables future‑proof and sustainable operations Reduces CO₂ emissions in industrial processes Ideal for industries producing excess hydrogen

Flexible Application Design

Designed for: Industrial heat recovery systems Flue gas energy recovery Combined heat and power (CHP) plants Customizable configurations to meet specific project needs Can be integrated into both new and existing systems

Efficient Heat Transfer Technology

Based on flame tube / smoke tube principle Hot flue gases pass through pipe bundles, transferring heat to water Optimized heat exchange maximizes energy recovery efficiency Ensures reliable hot water generation from exhaust energy sources

Optional Auxiliary Combustion

Without auxiliary combustion: Operates using only waste heat With auxiliary combustion: Functions as a hybrid system with additional burner support Combines conventional heating with heat recovery Configuration depends on project requirements

Durable & Low‑Loss Construction

Thermal insulation minimizes radiation losses Robust metallic casing for industrial durability Boiler support structure distributes load evenly across floor area Designed for long‑term operation in demanding environments
