Description

Improved hot-water heating stove

Technical field

The utility model belongs to the improvement of service water radiator, relates to a kind of improved hot-water heating stove.

Background technology

At present, raising along with people's environmental protection and energy saving consciousness, people have developed the hot-water heating stove of a variety of forms, commonly install additional between one deck shell and the hearth wall in the hearth wall outside again and form cyclic water jacket, and are for people to use with the water in the heat heating water jacket of the generation of the coal burning in the burner hearth.Outside the also chimney on body of heater that has one deck cyclic water jacket is set again, and in this water jacket, is provided with the coiling endothermic tube, form " crossing hydro-thermal " device, to improve the utilization rate of heat energy.But the recirculated water jacket layer of these stoves is generally thicker, and water capacity is big, makes that the water heat absorption in the water jacket is slow, and the water circulation is slow, therefore considerable heat energy dissipation is arranged still and can not make full use of.

Summary of the invention

The purpose of this utility model is to provide a kind of improved hot-water heating stove, and the water circulating speed in the cyclic water jacket is accelerated, thereby further improves the utilization rate of heat energy.

The purpose of this utility model is achieved in that a kind of improved hot-water heating stove, comprise by interior, the body of heater that outer two layers of walls constitutes, the bottom is provided with the burner hearth and the chimney of fire grate, in the hot-water heating stove each several part, all form cyclic water jacket between the outer wall, the winding of chimney cyclic water jacket inner disc is equipped with endothermic tube, be respectively arranged with circulating water inlet and the outlet pipe that communicates with cyclic water jacket in the bottom of body of heater and the top of chimney, between burner hearth and the body of heater rear wall firebreak that is constituted and be connected with body of heater roof and two side water jacket respectively by cyclic water jacket is being set, burner hearth hangs by the circulating water pipe that is connected with furnace water jacket and is fixed in the body of heater, and the thickness of described cyclic water jacket is 4-8mm.

During use, circulating water inlet and outlet pipe are connected with the room heater circulation line respectively, water in the rapid heating furnace water jacket of heat that coal burning in the burner hearth produces, because hearth water sleeve thickness is less, 4-8mm is only arranged, therefore the water in this water jacket can also seethe with excitement rapidly by very fast expanded by heating, because hot water proportion is lighter, cold water proportion is bigger, therefore hot and cold water is divided into two-layer up and down rapidly and begins circulation, hot water rises and enters in the body of heater cyclic water jacket and from being positioned at the outlet pipe inlet chamber heating pipeline at chimney cyclic water jacket top, cold water then enters in each cyclic water jacket of hot-water heating stove from water inlet pipe continuously, goes round and begins again to absorb the heat energy that coal burning produces rapidly.The utility model and existing hot-water heating stove are compared, have the following advantages: 1, because its cyclic water jacket more (as being provided with the cyclic water jacket firebreak), pass through the passage of the coal smoke that contains heat energy between firebreak and body of heater diapire that coal burning produces, firebreak can absorb heat energy wherein, therefore more can effectively utilize heat energy; 2, cyclic water jacket thinner (water jacket thickness has only 4-8mm), heat absorption is rapid, water circulating speed is faster; 3, burner hearth hang to be provided with, and the spacing between burner hearth and the inboard wall of furnace body is bigger, makes the coal smoke airway unobstructed, helps that coal burns more fully, heat production is rapid, more helps the cyclic water jacket heat absorption.
