Main Product Description

Used Econotherm (UK) Ltd. Model GG1922/CS/S/S industrial heat pipe heat exchanger and waste heat recovery system, engineered and designed for Southwire Company LLC in 2025, with a nominal thermal heat recovery capacity of approximately 1,921,553 watts (1.92 MW), equivalent to approximately 6.56 million BTU/hr. The system is designed to recover waste heat from high-temperature industrial exhaust gases and transfer it to a separate incoming fresh-air stream without direct mixing of the two air streams. Design operating conditions include an exhaust gas mass flow rate of approximately 42,640 kg/hr (94,005 lb/hr) and fresh-air mass flow rate of approximately 40,690 kg/hr (89,706 lb/hr). Under the specified conditions, exhaust gas enters at approximately 260°C (500°F) and exits at approximately 113°C (235°F), while incoming fresh air is heated from approximately 38°C (100°F) to 207°C (405°F). The heat exchanger features a heavy-duty insulated carbon steel casing and multiple heat pipe banks constructed from ASTM A179 cold-drawn seamless carbon steel tubing. Individual sealed heat pipes utilize specially prepared water as the internal working fluid, transferring heat through evaporation and condensation. Designed for continuous industrial operation with a minimum anticipated equipment design life of 20 years, this industrial waste heat recovery system is suitable for evaluating applications involving exhaust heat recovery, combustion air preheating, industrial air heating, and improved thermal efficiency in compatible high-temperature processing operations.

Frequently Asked Questions (FAQs)

- What is the model of this Econotherm waste heat recovery system?

The equipment is an Econotherm (UK) Ltd. Model GG1922/CS/S/S industrial heat pipe heat exchanger.

- What is the heat recovery capacity of this heat exchanger?

The system has a nominal design heat recovery capacity of approximately 1.92 MW thermal, equivalent to approximately 6.56 million BTU/hr.

- How does this Econotherm heat pipe heat exchanger work?

The system uses sealed heat pipes containing a specially prepared water working fluid. Heat from the hot exhaust gas causes the working fluid to evaporate inside the heat pipes. The vapor transfers heat toward the cooler air side, where it condenses and releases thermal energy. The cycle transfers heat between the two process streams without direct mixing.

- What is the exhaust gas inlet temperature?

The specified exhaust gas inlet temperature is approximately 260°C (500°F).

- What is the exhaust gas outlet temperature?

Under the stated design conditions, the exhaust gas outlet temperature is approximately 113°C (235°F).

- How hot can the incoming fresh air become?

Under the specified design conditions, incoming fresh air is heated from approximately 38°C (100°F) to 207°C (405°F).

- What is the exhaust gas flow rate?

The specified exhaust gas mass flow rate is approximately 42,640 kg/hr, equivalent to approximately 94,005 lb/hr.

- What is the fresh-air flow rate?

The specified fresh-air mass flow rate is approximately 40,690 kg/hr, equivalent to approximately 89,706 lb/hr.

- Does the exhaust gas mix with the fresh-air stream?

The system is designed to transfer heat between separate exhaust gas and fresh-air streams without direct mixing.

- What materials are used in the heat exchanger?

The unit features an insulated carbon steel casing and heat pipe banks constructed from ASTM A179 cold-drawn seamless carbon steel tubing.
