If the boiler operates 24 hours a day, a boiler efficiency of about 90%, heavy oil at 85/L, and a recoverable heat amount of 265KW can be achieved!
Generally, the blowdown water from the boiler is around 150°C. By utilizing this waste heat for preheating the boiler feedwater, it assists in heating the boiler and contributes to energy savings. First, the intermittent blowdown water is overflowed through a heat exchanger, and the feedwater continuously passes through the heat exchanger, allowing for the recovery of the intermittent heat from the blowdown water and raising the feedwater temperature. 【Case Overview】 ■ Use of a heat exchanger for blowdown water waste heat recovery ■ Feedwater continuously passes through the heat exchanger to recover the intermittent heat from the blowdown water and raise the feedwater temperature ■ When the boiler operates 24 hours Boiler efficiency is about 90%, heavy oil at 85 yen/L, and a recoverable heat quantity of 265 kW is achievable ■ In terms of heavy oil, this can result in energy savings of 58,000 yen per day, amounting to 17,430,000 yen annually *For more details, please refer to the PDF document or feel free to contact us.

Company information
We optimize all types of heat exchangers, from high-efficiency plate heat exchangers to titanium exhaust heat recovery spiral heat exchangers. Furthermore, we offer a unique lineup of products, including high-efficiency compact heat pump chillers and large cooling components, addressing various unused energy sources such as exhaust gas, wastewater, seawater, and ultra-pure water. As experts in thermal energy, we respond to various inquiries related to heat exchangers. Specializing in the design of special heat exchangers and unused heat recovery (such as hot spring wastewater, exhaust heat from food factories, and sewage heat), we provide a range of energy-saving proposals related to "heat," from design to consulting. In this era where continuous energy saving is necessary for each factory, we also hold study sessions on thermal energy for employees and stakeholders. We can tailor the content to meet the needs and preferences of participants, covering explanations of heat exchangers, thermal energy, its utilization, and related concepts. We can provide proposals and consultations that align with on-site needs, so please feel free to reach out regarding any thermal energy matters. We offer energy-saving proposals to our customers through heat exchange!
