High-pressure preheaters for power plants
In power plant operations, optimizing the cycle efficiency and reducing fuel consumption are major challenges. Preheating feedwater before it enters the boiler is a crucial process to enhance performance and lower operational costs.
Increase feedwater temperature and save fuel
The HP preheater by BORSIG Process Heat Exchanger GmbH is specifically designed for power plant cycle processes. It functions in the high-pressure area between the boiler feed pump and the evaporator inlet to preheat feedwater, significantly improving the inlet temperature. Preheating lowers the energy required for the boiler to evaporate the feedwater, thereby reducing fuel consumption and increasing overall process efficiency. The preheater utilizes superheated steam from the turbine, extracting heat in the desuperheater section. This process condensates the steam, and the subsequent condensate cooling extracts additional heat, which is then supplied to the feedwater. The unique design includes special installations that accelerate the condensate for better heat transfer. BORSIG offers these preheaters in various designs, catering to specific process conditions and specifications with complete solutions provided by qualified staff. Constructed at their Gladbeck facility, the heat exchangers meet the DGRL AD 2000 and API standards.
