SITA UK’s Request for Hydroblast Refractory Removal Services
SITA UK is an Energy-from-Waste Plant in Teesside. This plant alone diverts up to 200,000 tonnes of waste from our landfills every year. SITA UK came to Hydroblast earlier in April to request some Refractory Removal from inside the plant.
What is an Energy-from-Waste Plant?
Energy-from-Waste Plants (EfW) are being built up and down the country but many people don’t know what they are. These plants are an eco-friendly alternative to landfill. In the UK, we have a lot of landfill locations which are basically a giant, stinking pile of waste which takes years to decay. Instead of placing rubbish in a landfill and watching it rot, Energy From Waste Plants are being built to take household rubbish and turn it into energy which we can then use across the country. The energy produced can be used for electricity and/or heat.
What is Refractory Removal?
Heat and electricity is produced through the Energy-from-Waste Plant through combustion. From the intense heat which is required for the combustion process, the fire wears away the ‘fire brick’ or Refractory Lining. Refractory Removal is essential for inspection, repair, maintenance and replacement.
There are a few techniques which can be used for Refractory Removal including pneumatic breakers and high pressure water jetting which we will discuss more below.
Previously SITA UK opted to use a lot of man power and pneumatic breakers in order to break away the refractory lining. However using this tactic can have quite a lot of disadvantages including:
- Pneumatic breakers can puncture the central heating pipes which can create a lot of extra, unnecessary work and downtime
- This type of manual labour could lead to the workers suffering from HAVS or Hand and Arm Vibration Syndrome
- The lack of power from pneumatic breakers can cause the task to take a lot longer than needed
Plants such as SITA UK can burn up to 1,000 tonnes of waste within a 24 hour period. The council pays £250 per tonne for disposal and they then sell the electricity back to the grid. Any time with the plant not working to its full potential can be very costly for the plant so downtime, extra work and errors are not welcomed.
Why Ultra-High Pressure Water Jetting is the Solution
At Hydroblast, we use a range of ultra-high pressure water jetting equipment and for this task we chose to use our new Aqua Cutter 410 Robot. There are many benefits to using high pressure water jetting equipment such as the Aqua Cutter Robot as opposed to pneumatic breakers including:
- More efficient with less down-time for maintenance work
- Easy to position in harder to reach locations making it perfect for this task as the location was on the ceiling
- Small and light whilst remaining powerful and agile
- The Aqua Cutter has a Power Control Module or PCM which means the robot can be controlled wirelessly permitting the operators to work at a safe distance
- The Aqua Cutter also comes fitted with an Equal Distance System (EDS) which keeps a preset distance between the nozzle and surface, this technique reduces wasted energy and keeps the water jetting at a consistent and powerful speed
Refractory Removal using ultra-high pressure water jetting equipment such as the Aqua Cutter 410 robot can be up to 10 times faster than traditional Refractory Removal techniques. Using high pressure water jetting for Refractory Removal is a safer, more efficient and cost-effect solution.
