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.
