Among significant HRSG projects announced by NEM Energy so far this year was an agreement with Metrostav to supply two state-of-the-art heat recovery steam generators for ČEZ Group’s new combined cycle power plant in Mělník, Czech Republic. In addition to producing electricity, the plant will also provide district heating. The NEM HRSGs will incorporate district heating modules that ensure a dependable heat supply to the district heating networks of Mělník and Prague.
The new natural gas fuelled combined cycle plant will replace coal fired units at the power plant site, marking a decisive step towards a cleaner energy mix in the Czech Republic.
The NEM supplied heat recovery steam generators are being designed as vertical-exhaust-gas-flow drum type HRSGs employing a very modular design. The modular units will be delivered in a highly pre-fabricated state, allowing the client to install the units in a very short time frame with less welding requirements on site when compared with a conventional horizontal-exhaust-gas-flow heat recovery steam generator. The reduced construction time saves the client time and money, and also reduces site construction risks. Since the launch of the concept, NEM Energy says it has successfully supplied dozens of these modular installations worldwide.
NEM Energy has also reported an order for the delivery of two horizontal-exhaust-gas-flow heat recovery steam generators for a project in Taiwan. These HRSGs, with three pressure levels + reheat with SCR (selective catalytic reduction) will be installed behind two Siemens Energy SGT6-9000HL gas turbines for the Kuo Kuang 2 (KK2) power plant in Taoyuan City. With a total output of 1200 MW, this power plant is seen as a key infrastructure project aimed at addressing growing energy demand in Taiwan with consequent power shortages, while at the same time supporting the shift from coal.
Meanwhile in Texas, NEM Energy, under a contract with Siemens Energy, is supplying two horizontal-exhaust-flow heat recovery steam generators for a new 1.2 GW combined cycle power plant that will support the end user, Sandow Lakes Energy Company, in “delivering a reliable and efficient power supply to its customers.”
The new power plant will be equipped with NEM’s patented DrumPlusTM HRSG design, giving the plant enhanced fast start and cycling capabilities, and allowing it to “operate in harmony with the fluctuating renewables on the grid.”
A further HRSG project reported by NEM Energy was the supply of two horizontal-exhaust-gas-flow heat recovery steam generators, with exhaust gas bypass systems, for a new combined cycle power plant in Saudi Arabia. The plant, with an installed capacity of about 1300 MW, is expected to be in operation by the end of 2028.
The order was placed by Spanish company Técnicas Reunidas, which is acting as engineering, procurement and construction contractor for the Saudi project. NEM Energy notes that it already has numerous HRSG units in operation across Saudi Arabia.
