Abstract

The utility model relates to an efficient energy-saving normal pressure hot water boiler, which is the efficient energy-saving normal pressure hot water boiler mainly used for heating and bathing. The utility model gives a new structure which can thoroughly use the heat of the boiler to solve the problems of the dust fall of the fume dust. The efficient energy-saving normal pressure hot water boiler of the utility model, which is composed of a burning chamber, a heat pipe bundle, five heat radiation dust falling tanks, etc. All structures for the fume in the boiler are formed by the combustion chamber, the five heat radiation dust falling tanks formed by water wall, the heat pipe bundle and an exit flue. The solid rotation of the flue is formed by five times of dust fall and nine times of heat radiation (or heat exchange) causes the heat of the fume to be thoroughly utilized. Thus, the heat efficiency of the boiler is raised and the heat is effectively saved.
