ITRI's waste heat power generation technology: an energy-saving and cost-efficient tool

2018-11-16

Whether in the petrochemical, steel, or machinery industries, waste heat generated during production has always been a serious problem. It's a great pity if the emitted waste heat, steam, and radiant heat are not recovered and utilized. However, the Industrial Technology Research Institute (ITRI)'s "Low-Temperature Thermal Energy Thermoelectric Power Generation Application Technology" can now turn this waste heat into valuable resources. This technology has also been favored by NASA experts, winning the NASA Tech Briefs "Creating the Future Award" in September of this year, recognizing it as one of the top 100 sustainable technology innovations. With long-term R&D support from the Bureau of Energy, Ministry of Economic Affairs, ITRI's ORC technology can be applied not only to geothermal power generation but also to low-temperature power generation, which is often overlooked in the aforementioned industrial processes. In previous manufacturing processes, high- and medium-temperature waste heat was relatively easy to recover. However, low-temperature waste heat (air <250°C or hot water <100°C) was mostly dissipated and emitted. The Organic Rankine Cycle (ORC) cryogenic thermoelectric power generation system developed by the Industrial Technology Research Institute (ITRI) can recover industrial waste heat from 80°C to 300°C, representing genuine waste resource utilization. Currently, 10kW, 50kW, 60kW, and 200kW screw expanders, as well as 125kW and 300kW turbine expanders have been developed. After waste heat power generation, the estimated energy-saving benefits start from NT$1 million per year, with a payback period of approximately 2-5 years after construction. For example, this year, ITRI (Industrial Technology Research Institute) collaborated with Yieh Phui Steel to successfully build a 132kW ORC waste heat power generation system, generating 1.12 million kWh of electricity annually and reducing carbon emissions by approximately 700 metric tons per year, equivalent to the carbon absorption of 1.8 Daan Forest Parks. This also saves approximately NT$3 million in electricity costs annually, successfully demonstrating the achievements of domestically developed turbine ORC technology. ITRI's Green Energy Laboratories stated that while similar technologies exist internationally, their high cost deters factories considering waste heat power generation. To reduce the cost of organic Rankine cycle thermoelectric generator sets, ITRI successfully partnered with leading Taiwanese refrigeration and air conditioning manufacturer Hanbell Precision Machinery Co., Ltd., to jointly develop a dedicated semi-closed screw expander and semi-closed turbine expander for ORC. This low-cost, self-developed ORC core engine is key to this technology winning NASA's "Future Creation Award." Currently, the screw-type ORC system technology has been transferred to domestic manufacturers, continuing its commercialization process and being adopted by multiple customers. With a domestic self-sufficiency rate exceeding 95%, the technology's feasibility has been successfully verified, driving the development of the energy-saving industry. ITRI (Industrial Technology Research Institute) can optimize system design and assess economic benefits based on customers' process requirements and different heat source temperatures and flow rates. It can tailor complete waste heat power generation systems for industries with different processes, providing a one-stop solution service. Energy savings are expected to start from NT$1 million per year, easily turning waste heat into gold. (Written by: Yuan Haoting) Source: Commercial Times (2018/09/27)
