Evolve Polymers Heat Recovery Boiler
Project Type:
Recycling Waste Heat into Energy
| Client:
Evolve Polymers
|
Location:
Evolve Polymers, Hemswell, Lincolnshire
Challenge
To reduce energy costs by converting waste heat from two existing Aggreko gas generators at the site into process steam used for heat sterilising the waste plastic recycled by the Company.
Solution
Installation of a Cochran Heat Recovery Boiler to generates 2 tonnes of steam per hour.
Result
Substantially reduced energy costs and carbon footprint, plus a net energy save well in excess of £500,000 pa.
Cochran recently installed a Heat Recovery Boiler system for Evolve Polymers at Hemswell in Lincolnshire. The project which made use of exhaust heat from two gas engines was completed in association with leading generator hire company, Aggreko.
The two generators constantly emit exhaust gasses at in excess of 460°C; heat which was previously going to waste. Cochran’s extensive experience in Heat Recovery Boiler design enabled the company to develop a hired boiler solution capable of utilising these previously wasted exhaust gases to generate 2 tonnes of production steam per hour.
The cost benefit of utilising recovered ‘free’ exhaust heat to make steam proved key to the overall viability of this project, effectively aligning the generated electricity costs with grid prices. This solution also offered additional benefits, including a significant reduction in boiler fuel oil consumption. The annual cost was £614,952, with of around £6,000 per annum: Hire of the Heat Recovery boiler costs them just £6,500 pcm, with no additional running costs - as a result they are saving £542,952 in energy costs every year.
