low energy demand and therefore innovative thinking is necessary regarding to the supply of the minor energy quantity, which is required for room heating and domestic hot water. In order to calculate the heat loss of a pre-insulated pipe system relatively precisely, it is necessary to include all the parameters influencing the heat loss. For that purpose, the calculation program Calculator was developed which takes into consideration the temperature dependent lambda value and the changes in insulation over time (ageing). storage tanks gives the opportunity to use smaller dimensions of service pipes. Therefore, new sizes for house connections were needed and new LOGSTOR Twin Pipe ø14mm with PUR foam and LDPE casing was developed. The combination of high-efficient insulation materials, gas diffusion barriers and small dimensions of service pipes, makes it possible, with the new service pipe, to reduce the heat loss in a house connection up to 70 %, compared to traditional connections. wood chips fuelled downdraft staged air gasification CHP plant by BioSynergi Proces ApS combustible producer gas. The conversion takes place in an air-staged Open Core downdraft gasifier. The producer gas is used as a fuel in a combustion engine in couple with an electrical generator. The complete plant is designed for automatically, unmanned operation. |
