Powering Reliability in
Coal-Fired Generation
For decades, Thermal Engineering International (TEi) has been a trusted partner to the coal-fired power industry, delivering high-performance thermal equipment that improves reliability, efficiency, and long-term asset performance. Our comprehensive portfolio, including feedwater heaters, steam surface condensers, and shell-and-tube heat exchangers, is engineered to meet the demanding thermal conditions of conventional fossil fuel plants.
At TEi, we understand the operational pressures of base-load generation. That’s why our solutions are built to endure high thermal loads, variable cycling conditions, and aggressive operating environments. From high-pressure feedwater heaters designed to manage extreme superheat and abnormal flow, to surface condensers that maximize thermal efficiency and uptime, every product reflects our commitment to precision engineering, quality manufacturing, and industry-leading performance.
With extensive field experience, a robust legacy of innovation, and a deep understanding of coal-fired systems, TEi provides the equipment, expertise, and support to help coal plants continue to deliver reliable, cost-effective power in a transitioning energy landscape.

Condensers & Modules
Our condenser designs can incorporate enhanced deareation systems, and/or a variety of turbine exhaust options, which can assist in improving plant layouts. We continually address and refine these and other considerations associated with circular designs where space is at a premium. The surface condenser is a critical component in the operation of a steam power plant. Condenser failures can result in forced outages and loss of generation capacity. TEi condensers represent an evolution of advanced technology, offering improved thermal efficiency and advanced mechanical design to reduce forced outages and increase availability.
As the innovator in heat transfer technology, TEi provides exceptional modular changeout options for steam surface condensers. Modular changeouts are an efficient alternative to the conventional retube. Existing condensers can be refurbished, redesigned, and even upgraded to meet new performance demands and power requirements. Complete surface condenser retrofits are possible and can offer a multitude of benefits. A surface condenser is critical to the efficient operation of a power plant.

Feedwater Heater
Each feedwater heater can extract up to 30% of the turbine throttle steam and is designed to specific thermal conditions and manufactured for a singular purpose. The low pressure feedwater heaters play a key role in maintaining efficient, trouble-free operation of your generation facility and the vertical channel down (VCD) designs offer a small footprint, piping economics and simplified bundle access.
TEI’s feedwater heaters are each designed to specific thermal conditions and manufactured for a singular purpose. Whether it be sophisticated designs involving extreme superheat, abnormal flow conditions or dissipation of high energy fluids, TEi has the expertise and experience to offer proven solutions to any design problem. TEi provides innovative and practical concepts to ensure peak heater performance from installation to testing through full or part-load operation. We offer a multitude of design configurations for desuperheater and drains cooler zones as well as the latest in channel closure techniques. The three most common are listed below:
- Bolted-Gasketed Closure – This economical, gasketed pill box is easily disassembled for full access.
- Seal-Welded Diaphragm Closure – This economical welded closure is leak-proof and easily disassembled for full access. It requires no gaskets.
- Breech-Lock Closure – This widely accepted, quick opening closure provides full access to the tubesheet and structural reliability under varying temperature and pressure conditions.

Shell & Tube Heat Exchangers
TEi has successfully supplied numerous optimized BOP and CCW designs for numerous fossil and nuclear power plants undergoing power up-rates and routinely provides solutions for power plants needing to improve efficiencies. With diverse high-quality applications, impressed current & galvanic anodic protection, elimination of potential cross-contamination of fluids, compact construction when designing for fluids with high thermal resistances and can be externally and internally applied, TEi’s mission-critical equipment helps ensure a stable, optimal operating temperature while reducing costs and dramatically improving efficiencies for our customers.
Provides a thermal bridge between systems, supporting heat transfer from closed-loop systems to ultimate heat sinks with reliability and control.
Cools turbine components for improved efficiency and extended equipment life during peak load and continuous operation.
The lube oil cooler is to maintain oil temperature of the turbine lube oil by utilizing cooling water through the tubes. TEi provides shell & tube TEMA type heat exchangers for this service.
Condenses steam from turbine glands to maintain vacuum integrity and improve condenser system efficiency.
Recovers waste heat from boiler blowdown processes, improving overall plant heat rate and reducing energy loss.
