District-heating scheme helps project in Ireland go a little greener
District heating that includes a biomass boiler provides heating and hot water for homes on this new development in Ireland, with each one connected to the system by an Alfa Laval Cetetherm Mini heat-exchange module.
A biomass boiler provides heating and hot water for the first major district-heating scheme in Ireland. It serves a housing development in Dundalk, with heat-exchanger units from Alfa Laval linking individual dwellings to the system. The objective is to reduce emissions by 90% compared with other approaches, increase energy efficiency by 30% and reduce energy costs by 30%. Carlin Hall is being developed as one stage of a major project called the Dundalk Sustainable Energy Zone, an area of four square kilometres that will comprise housing, schools, hospitals and schools and act as a focus for sustainable-energy initiatives. Carlin Hall’s mix of 2-, 3- and 4-bedroom apartments, semi-detached and detached houses are being built by Keelagh Group, with a district-heating system designed by Bio Energy Power Systems. The central biomass boiler is supported by a gas boiler to produce 1.2 MW of heat in all. Each dwelling has an Alfa Laval Cetetherm Mini sub-station to provide individual control of water and heating temperatures. It includes a heat meter to measure energy consumed. The Cetetherm has separate heat exchangers for radiators and instantaneous thermostatically controlled domestic hot water Cormac Power, technical director of BioEnergy Power Systems, says, ‘Carlin Hall Dundalk is the first large-scale district-heating project to be undertaken in Ireland. As it is a showcase development, we have used the best technology currently available.’
