Bullet-proofing your Steam System for Winter

As the winter season is in full swing, businesses and industries with steam systems face the challenge of maintaining optimal energy efficiency and reliability. Steam systems play a crucial role in various sectors, including pharmaceuticals, healthcare and food and drink.

In this blog post, we will explore strategies to winterise your steam system, ensuring it operates at peak performance while minimising energy consumption.

1. Conduct a Thorough System Audit:

Before the winter months fully set in, conduct a comprehensive inspection of your steam system. Check for leaks, insulation integrity, and potential points of heat loss. Identifying and addressing issues early on will contribute to energy savings and enhance the overall reliability of the system. A Spirax Sarco Energy Audit is tailored to your process or application and your budget. An audit can include the complete steam distribution loop, starting with the water treatment plant, right through to process applications and condensate return. We can scope an audit to fit your needs, for instance it can be focused on energy efficiency, health & safety, or best practice.

2. Insulate Steam Pipes and Components:

Proper insulation of steam pipes and components is essential to prevent heat loss. During winter, uninsulated pipes and components can lead to significant energy waste as heat dissipates into the surroundings. Install high-quality insulation to keep the steam at the desired temperature throughout its journey from the boiler to its destination.

Put simply, good insulation = Less heat loss improved energy efficiency), but also - fewer traps required (less CapEx), fewer traps to maintain (less OpEx); fewer potential points of failure; more energy in the steam (energy saving, again); less heat loss = less erosion, corrosion, and water hammer.

4. Implement Regular Maintenance:

Scheduled maintenance is key to the longevity and reliability of any system. Establish a routine maintenance schedule for your steam system, focusing on cleaning and calibration. This proactive approach can identify and address potential issues before they escalate, minimising downtime and ensuring optimal performance.

5. Utilise Condensate Recovery:

Implementing a condensate recovery system allows you to reclaim and reuse condensate, reducing water and energy consumption. By returning condensate to the boiler, you maximise efficiency and minimise the need for additional energy to heat fresh water.

This is probably the quickest win there is after steam trap surveys, remember the rule of thumb:  6c temperature improvement = 1% Fuel saving.

6. Optimise Boiler Water Treatment:

Proper water treatment is essential to prevent corrosion and scale build-up in the boiler. During winter, water conditions can change, making it crucial to monitor and adjust water treatment parameters accordingly. Regular testing and adjustment of water treatment chemicals will help maintain the efficiency and reliability of your steam system.

Service and calibrate your pumps to maintain required TDS and TDS blowdown within the range recommended by Boiler OEM. Too much = Energy loss BUT too Little = scaling on Boiler tubes, excess foam & scale in pipework (barrier to Heat X and Maintenance issues).

7. Install Steam Traps:

Well-functioning steam traps are crucial for removing condensate and ensuring that only dry steam enters the distribution system. Faulty or malfunctioning traps can lead to energy waste and decreased system reliability. But it’s not JUST incorrectly operating traps, but also traps that have been incorrectly selected (type) or sized; installed incorrectly or exposed to a poor quality of steam that will cause them to fail. Regularly inspect and replace steam traps as needed.

Whether you want to check the health of your steam traps, or partner with us to ensure your processes run trouble free, our Complete Steam Trap Management programme can be tailored to suit your needs, offering a total customer solution.

Any steam traps found to be needing maintenance will be specified, supplied, and installed as part of the fixed price contract. The cost of a Steam Trap Management Contract is typically far less than the cost of the average energy loss caused by not maintaining your steam trap population regularly. 

1. Metering

Spirax Sarco's metering products play a crucial role in promoting energy efficiency during winter months. By offering precise and reliable measurement of steam and other fluids within industrial processes, these products enable organisations to optimise their energy usage.

In winter, when heating demands are heightened, the accurate monitoring and control of steam flow, temperature, and pressure become paramount. Spirax Sarco's metering solutions empower businesses to fine-tune their heating systems, ensuring that energy is utilised efficiently and only when needed. This not only helps in reducing energy consumption but also minimises operational costs.

Like a steam trap – a meter needs to be selected, sized and installed correctly – and should be installed with the appropriate ancillaries and in the correct flow orientation and run of pipework upstream and downstream, NOT as a ‘standalone product’ and also serviced and calibrated regularly.

The integration of Spirax Sarco's advanced metering products in industrial settings contributes to a more sustainable and environmentally responsible approach to winter energy management, aligning with the growing emphasis on eco-friendly practices in today's business landscape.

Winterising your steam system is a proactive and essential step in ensuring energy efficiency and reliability during the colder months. By conducting thorough inspections, investing in proper insulation, upgrading equipment, implementing regular maintenance, and utilising advanced technologies, you can optimise your steam system's performance. These measures not only contribute to cost savings but also enhance the sustainability and resilience of your operations throughout the winter season and beyond.
