BOILERS, PUMPS & VALVES


FRENCH PASTA MANUFACTURER SEES HEATING COSTS DROP BY 68% THANKS TO HEAT PUMPS


I


n 2022, facility managers at French pasta manufacture Sean Jean were looking for a temporary 150kW cooling capacity to


cover the additional summer load in one of their plants. What started as a typical project, however, evolved into a game-changing approach to industrial heating, changing the mindset that has placed heating and cooling in separate silos. During the site visit, Trane Rental Services team analysed


Saint Jean’s overall cooling and heating demands. The plant needed cold water temperatures of -8˚C/-4˚C and hot water temperatures of 60˚C/55˚C.


Instead of recommending an additional chiller to satisfy the temporary cooling needs, the engineers


proposed a new heat pump solution that would not only deliver the additional cooling capacity Saint Jean managers were looking for, but also completely replace the plant’s 300kW fossil-fuelled boiler heating system – generating significant energy savings in return. Following a detailed analysis of the heat requirements, the team installed two Trane City RTSF water-to-water


heat pumps, connecting them with the plant’s existing chillers, which allowed them to harness the waste heat that typically gets lost to atmosphere during cooling process. The new renewable energy heating set up offered the manufacturer opportunities to lower their energy consumption and associated costs. During the four months of rental operations, the calculations showed that, thanks to shutting down the gas boiler


and replacing it with heat pumps, the cost of generating heat dropped by approximately 68% from over 8,400 EUR to 2640 EUR. This also helped lower the carbon footprint of the plant and meant more sustainable operations.

POWER DEMANDS C HIGH EFFICIENCY HEAT PUMPS SLASH ENERGY


COSTS BY 66% FOR SOCIAL HOUSING RESIDENTS S


mall and super-efficient Kensa ground source heat pumps and Sunamp heat batteries have been installed in three


tower blocks in Chadwell St Mary’s, owned by Thurrock Council. By replacing the old storage heaters with 300% efficient ground


source heat pumps, residents in the two-bed flats will be shielded from future price rises this winter and reap additional savings of up to 66% on their heating and hot water bills Diane Barr, a resident from Thurrock, stated: “The heat pump is


much warmer and the hot water is so fast compared to the old system. Plus it’s so cheap - I pay around £21 a week, and that’s with doing the washing, using the tumble-drier and dehumidifier. With the storage heaters, it cost around £70 a week, and I only used to have the heating on in three rooms. The hot water also ran out pretty quickly so we couldn’t have a shower.” Thurrock Council secured £3.2million from Wave 1 of the Government’s Social Housing Decarbonisation


Fund (SHDF) to help finance the scheme and it is the largest ground source heat pump retrofit project completed under the scheme. The SHDF, a £3.8 billion 2019 manifesto commitment, aims to support local authorities and social landlords to retrofit their housing stock at scale over 10 years.

Facilities such as power plants and refineries have demanding, high-flow gas and fluid delivery processes and need valves that are efficient, reliable and easy to maintain across thousands of hours of


operation,” said Anne Sophie Kedad, director of marketing with Emerson’s discrete automation group. To help, Emerson has launched the ASCO Series 327C solenoid valve. This has a direct-acting, high-flow design


that provides superior flow-to-power ratio; and features a balanced poppet construction that permits high flows at minimum power levels, making it ideal for use in power plants, refineries and chemical processing facilities. The valve has features that combine reliability and durability to increase operational efficiency and


improve process certainty. It also has a two-layer dynamic seal technology that provides low friction and excellent stiction resistance.

hina is leading the world in the construction of solar, wind and


thermal power plants to support its increasing demand for electrical energy. For those that use steam turbines, boiler feed pumps (BFPs) are a crucial asset and selecting the best design to suit the needs of an individual station can have many benefits. When a recent project needed some of the largest start-up BFPs available, Sulzer was appointed to supply two start-up BFPs capable of delivering flows greater than 1000m3


/h. Sulzer’s solution uses a 2-pole, 5.6 MW


motor that runs at 3,000 rpm, which allows for a direct connection to the GSG- BFP pump. The hydraulic design ensures that the required net positive suction head (NPSH) is achieved without the need for a booster pump. This makes the overall footprint of the pump skid more compact and ensures a cost-effective solution for the power plant. Tang Qixu, tendering manager, Power


for Sulzer, commented: “Sulzer was primarily selected for this contract because of our renowned ability to deliver high-quality pumps with industry- leading efficiency figures. In this case, we achieved excellent performance thanks to the expertise of our designers and manufacturing facilities.” Sulzer’s modern GSG-BFP pumps had a


high efficiency over 80%. When talking about pumps with multi-megawatt motors, these real-world efficiency figures would deliver a considerable saving, the company explains. Sulzer’s latest addition to the power


generation market will be delivered later this year with installation and commissioning being supported by the company’s field services engineers.
