Technology

Currently, Tullis Russell’s on-site production of heat and electricity is achieved with a combination of its own coal- and gas-fired CHP plant. 

Combined Heat and Power (CHP) plants provide the most efficient way of converting a fossil or renewable fuel into useful heat and power.  CHP technology is highly energy efficient technology and utilises the waste heat from electricity generation to provide useful heat.  CHP delivers up to 20% energy savings when compared to the separate production of heat and electricity. This leads to lower  fuel consumption, fuel costs and carbon emissions. CHP also  avoids electrical transmission losses otherwise incurred by importing electricity adding to the energy efficiency benefits of the technology

The plant will consume around 400,000 tonnes per annum of biomass, including both “virgin” and recycled wood using a fluidized bed boiler and flue gas system which will be designed to comply with the Waste Incineration Directive.  Recycled wood diverted from landfill will be a major part of the plants fuel supply.

The new CHP plant will be capable of supplying up to 120 tonnes of steam per hour to the Tullis Russell paper mill and three gas fired boilers will also be installed to provide Tullis Russell with a secure supply of steam. Tullis Russell will consume approximately  17MW of electricity for the plant and approximately  25MW of electricity will be exported

The new RWE biomass CHP power plant at Tullis Russell will be the largest of its kind in Scotland, and will reduce Tullis Russell’s annual carbon emissions by 250,000 tonnes, reinforcing the company’s position as one of the worlds leading environmentally focused papermakers.
