Producing frozen ready meals primarily for the UK, Heinz's Dundalk plant uses steam in the cooking process and to heat the water used for washdown.
The plant had been using a large old firetube boiler but the decision was made to switch to two Babcock Wanson ESM7000 sequence-controlled Steam Generators with high efficiency Economisers as part of an ongoing plan to improve energy efficiency across all operations including the steam boiler system. These have been installed into a new custom-built boiler house.
A coil-type Steam Generator, the ESM provides operating efficiencies of circa 9697% overall and low emissions.
It uses modern controls to maintain a close ratio between the burner firing rate and water input with inverter drive of both the combustion air and feed water pumps. This ensures close control of both steam output and steam quality and lowest practicable consumption of electrical power.
