Modernisation of a paper factory boiler house with a 2-cylinder Spilling steam engine.
When the renewal of the entire steam boiler plant became necessary because of a heavy oil-fired boiler that was no longer up to date, the paper factory again decided to work with Spilling. The company had already operated an older Spilling steam engine with oil lubrication for years and wanted a Spilling steam engine again when replanning the boiler house. 

All was in favour of a Spilling steam motor due to the size of the plant and the fluctuating load take of the paper machines. The Spilling steam engine was dimensioned to suit the heating required to be supplied to the machines. Since the plant as a combined heat and power plant operated exclusively according to the heat demand, the company can receive a reimbursement on the energy tax paid on the natural gas used to generate steam.
