Abstract

The utility model relates to a high-efficiency energy-saving atmospheric hot water boiler. The utility model is provided with a boiler body. The lower part of the boiler body is provided with a fire grate. A boiler container is positioned on the upper part of the fire grate, and is fixedly connected with an inner boiler body through a convection flow heating pipe and a radiation heating pipe. The convection flow heating pipe is fixed on the upper surface of the boiler container, and the radiation heating pipe is arranged on the lower surface of the boiler container. The tail end of the boiler body is provided with a convection flow heating partition plate. The utility model with the novel structure has large radiation heating area, high heat efficiency, low temperature of the exhaust smoke and energy saving. The utility model is used as the civil boilers for heating and supplying hot water.

Description

Energy-efficient normal-pressure hot-water boiler

The utility model relates to civil boiler.

The shortcoming that present widely used hot-water boiler exists is that the thermal efficiency is low, wastes energy, and in order to address this problem, people have done multiple effort, as designs the hot-water boiler etc. of multiple improvement structure, but effect is not very good.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of simple in structure, thermal efficiency height, the energy-efficient hot-water boiler of energy savings.

Task of the present utility model realizes as follows: energy-efficient hot-water boiler has a body of heater, the body of heater bottom is provided with fire grate, being positioned at fire grate top is equipped with by be heated pipe and be fixed on the lower surface radiation flue that pipe and inner furnace body be connected that is heated of the convection current that is fixed on the flue upper surface, flue be shaped as cross section to circle, the longitudinal section is oval, at the body of heater afterbody convection current dividing plate that is heated is installed.

The utility model is because the cross section of flue be circular, and the longitudinal section be an ellipse, and the pipe below its side towards the fire and the flue can directly contact with flame, so the area of accessible radiation heat transfer is big, thermal efficiency height; Owing on flue, be welded with convection current by heat pipe, and installed dividing plate additional at the stove afterbody, can constitute convection heating surface and strengthen, reduced exhaust gas temperature, reduce thermal loss, energy savings.

Fig. 1 is the utility model front section view;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

A most preferred embodiment of the present utility model, as figure, energy-efficient hot-water boiler has a body of heater 3, constitute by inner furnace body 10 and external furnace body 11, the body of heater bottom is provided with fire grate 9, be positioned at fire grate top the radiation of being heated pipe 2 and being fixed on the flue lower surface by the convection current that is fixed on the flue upper surface flue 4 that pipe 5 and inner furnace body be connected that is heated is installed, the cross section that is shaped as of flue 4 is circle, the longitudinal section is oval, the convection current dividing plate 12 that is heated is installed in body of heater afterbody 1, be provided with into fuel fire door 6 in the front of boiler, fire door 7 pokes fire, ash disposal cinder notch 8, be provided with Water supplying tube joint 14 in the bottom of body of heater, top is provided with titting water outlet 13, also is provided with boiler water blow-down pipe 15 in the bottom of body of heater.

Convection current heat pipe 2 can be set more than 4 as 4,6,8,10 according to the model of boiler, and the utility model is selected 4 for use, and radiation heat pipe 5 can be selected for use more than 2 according to the model of boiler as 2,4,6,8, and the utility model is selected 2 for use.
