Abstract
The utility model discloses an integral type through-flow atmospheric hot water boiler, which comprises a heating surface water pipe, an upper annular collecting box, a lower annular collecting box, a combustion chamber and a cylinder body. The heating surface water pipe is arranged inside the cylinder body. The upper and lower ends of the heating surface water pipe are respectively communicated with the upper annular collecting box and the lower annular collecting box. The interior of at least one of the upper annular collecting box and the lower annular collecting box is equipped with at least one heat exchanger. The upper annular collecting box and the lower annular collecting box are communicated with each other through an adiabatic downcomer. According to the utility model, the interior of the boiler body is integrated with a heat exchanger, while a traditional primary circulation water pump and matched piping are no longer adopted. Therefore, the cost and the energy consumption for the primary circulation water pump are saved and the heat radiation loss of the primary circulation water pump and matched piping is also correspondingly reduced. Since the heat exchanger is integrated within the boiler body, the structure of the entire boiler system is more compact.
