Based on the situation that thermal insulation hot water tank and oil/gas fired hot-water atmospheric boiler keeps pressure-less, and oil/gas fired hot water atmospheric boiler is often installed on the roof disposing corresponding thermal insulation hot water tank, this paper proposes a kind of heat source device large-volume oil/gas fired hot water atmospheric boiler which is especially suitable for hot water supply system with the boiler installed on the roof. The water volume of this kind of boiler is equivalent to the thermal insulation hot water tank, and can be used for hot water supply...
