Waste Heat Steam Boiler

The Waste Heat Steam Boiler is a thermal energy conversion device specifically designed to recover high-temperature waste gas, waste liquid, or waste heat resources generated during industrial production processes and convert them into high-quality steam. Through efficient heat exchange technology, it transforms waste heat energy into reusable steam resources, and is widely used in energy-intensive industries such as steel, chemical, cement, papermaking, and waste incineration.

Core Values:

• Energy Saving and Consumption Reduction: Recovering waste heat reduces fuel consumption and lowers production costs;
• Environmental Compliance: Reducing carbon emissions and contributing to the "dual carbon" target;
• Resource Recycling: Achieving cascaded energy utilization and improving overall enterprise efficiency.

Waste heat steam boilers transfer the heat energy of industrial waste heat to boiler feedwater through a heat exchange system, generating saturated or superheated steam.

Typical Process:

• Waste Heat Input: High-temperature waste gas or process fluid enters the boiler flue/heat exchanger;
• Heat Exchange: Heat is transferred to the feedwater inside the boiler through finned tubes, spiral tubes, or plate heat exchangers;
• Steam Generation: The feedwater absorbs heat and vaporizes, generating steam with a pressure range of 0.5~10MPa;
• Waste Heat Dissipation: Low-temperature waste gas is treated to meet emission standards.

1. Extreme Energy Saving, Zero Carbon Emissions:

Fully utilizes waste heat, eliminating the need to burn fossil fuels, directly reducing overall energy consumption and greenhouse gas emissions.

2. Highly Customizable Design:

Non-standard designs are provided based on flue gas composition, volume, temperature, and user-required steam parameters.

Can be designed as a horizontal or vertical structure to adapt to different site spaces.

3. High-Efficiency Heat Transfer Technology:

Utilizes an extended heating surface, resulting in a high heat transfer coefficient, compact equipment size, and low metal consumption.

Optimizes flue gas velocity to prevent a balance between wear and ash accumulation.

4. Corrosion Resistance and Long Lifespan:

For sulfur-containing flue gas, strictly controls the minimum metal wall temperature to avoid low-temperature dew point corrosion.

Key components use heat-resistant alloy steel to extend equipment lifespan.
