High Temperature Flue Gas Recovery for the Paper Industry

High Temperature Flue Gas Recovery for the Paper Industry

During the papermaking process, especially during the pulp production and drying stages, large quantities of high-temperature flue gases are generated. These flue gases usually contain unburned organic matter and water vapor.

Flue gas collection: High-temperature flue gases are directed to recovery units by means of a flue gas collection system. These units typically include heat exchangers and filters to remove particulates and impurities.

Heat Recovery:

Heat exchangers: heat from the high temperature flue gases is transferred to other process water or air through heat exchangers. This can be used to preheat feed water, dry air, etc.

Utilization of Waste Heat: The recovered heat can be used to heat steam, heating or other process needs, thus improving energy efficiency.

Flue gas emission control: The treated flue gas will reduce the emission of harmful substances and comply with environmental standards.

Advantages

Energy efficient: Significantly reduces energy consumption by recovering and utilizing heat from high temperature flue gases.

Environmental protection: Reduces emissions of greenhouse gases and other pollutants, in line with sustainable development goals.

Economic Benefits: Reduces production costs and improves overall economic efficiency.
