Heat Recovery in A Textile Manufacturing Plant

Heat Recovery in a Textile Manufacturing Plant

Problem

A textile manufacturing plant faced high energy costs due to the need for constant steam production and heating.

Solution

The plant installed a finned tube heat exchanger to recover waste heat from the steam exhaust and use it to preheat water entering the boiler system.

Implementation

Heat Exchanger Design: The heat exchanger featured copper tubes with aluminum fins for high thermal efficiency and resistance to steam.

Configuration: The system used a crossflow configuration, with steam exhaust flowing over the fins and feedwater passing through the tubes.

Results

Efficiency Improvement: The preheating of feedwater resulted in a 25% reduction in boiler fuel consumption.

Cost Savings: The plant saved $180,000 annually on fuel costs.

Environmental Impact: The implementation led to a reduction of 600 tons of CO2 emissions per year.
