Waste Incineration #2

Industry: Medical Waste Incineration

Application: Waste Heat Recovery (WHR)

Country: UK

Power: 200 kW

Model: HP 204

Steam in/out: 10 Bar G / 0.5 Bar G

Second Heliex GenSet installation for UK’s leading medical waste services provider at its newly relocated and entirely self-sufficient waste -to -energy facility in the south west of England.

The client 

Our client, a forward thinking high energy user, operates a number of sites across the UK where medical waste is incinerated at temperatures as high as 1000°C. The company has already installed a Heliex System at one of its Northern England plants.

The project

It was a priority that the new plant embrace innovative power generation technologies, enabling it to utilise any onsite waste heat to meet the full electricity demand. Various technologies were explored to create a state of the art system that entirely meets its energy needs.

The solution 

A Heliex HP 204 Steam Expander System was incorporated into the sites process for cooling the incineration furnace gasses. A heat exchanger is used to absorb the heat from the furnace gasses to heat water, which is turned into steam. This steam goes through the Heliex System, where it generates electricity, before being condensed to water and then returned to the heat exchanger to start the process again. The system is expected to generate 1600 MWh.

Return on the Heliex system is approximately 2 years
