The utility model relates to normal pressure hot-water boiler technology using the molded coal as the fuel, which is characterized in that a baffle is provided along the direction of the coal delivering on the slideway to separate the major water cycle into two independent branch water cycles. In each branch water cycle, and an outflow tube and a water return pipe are connected with a water use tube line. When working, the boiler can simultaneously exchange heat for the independent branch water cycles, which can finish the usages like showering and heating. The utility model has the advantages of high service efficiency, full utilization of boiler output, dramatic declining on the effect of season.
