Combined Heat And Power (CHP) in A Manufacturing Plant

Combined Heat and Power (CHP) in a Manufacturing Plant

Problem

A manufacturing plant was looking to improve the efficiency of its combined heat and power (CHP) system and reduce overall energy costs.

Solution

The plant installed a finned tube heat exchanger to recover waste heat from the CHP system’s exhaust gases and use it to provide space heating and hot water for the facility.

Implementation

Heat Exchanger Design: The heat exchanger used carbon steel tubes with copper fins, designed to withstand high temperatures and corrosive exhaust gases.

Configuration: A counterflow configuration was chosen for maximum heat transfer efficiency, with exhaust gases flowing over the fins and water passing through the tubes.

Results

Efficiency Improvement: The plant improved its overall energy efficiency by 20%.

Cost Savings: The heat recovery system resulted in annual savings of $250,000 in energy costs.

Environmental Impact: The plant reduced its CO2 emissions by 700 tons per year.
