Abstract
The utility model relates to a hot water boiler used for indoor heating. A boiler body is cylindrical; the upper part and the lower part of a hearth are respectively provided with an upper and a lower heat exchangers which are communicated with a stove container; the outer circumferences of an upper and lower sealing plates of the heat exchangers and the inner wall of the stove container are welded into integration; the hearth is divided into an upper, a middle and a lower three parts which form a horizontal circle loop together with the stove container. Two rows of vertical and horizontal crossing hot water circulating pipes which are communicated with the stove container are arranged between the two heat exchangers, forming a reticular circulation loop. A sealing head of the stove container adopts an annular bow-shaped cross section structure; an upper and a lower air adjusting doors for cleaning ash are arranged on the stove body above the two heat exchangers; thereby, the combustion state in the stove can be adjusted. Because of the technical measure, the sufficient heat exchange of the heat energy of the high-temperature zone and the low temperature area of the hearth can be carried out; heat efficiency of the stove can be improved.
Description
One, affiliated technical field
The utility model relates to a kind of hot-water boiler for the indoor heating use.
Two, background technology
At present, the various hot-water boilers of the marketing, structure be in burner hearth, be provided with vertically, the horizontal circle steel pipe forms water-flow circuit and carries out heat exchange, its defective is that fuel combustion is insufficient, the heat energy heat exchange of high temperature, low-temperature space is insufficient, the thermal efficiency of stove is low.
Three, summary of the invention
In order to overcome the existing low deficiency of the hot-water boiler thermal efficiency, the utility model provides a kind of energy-saving hot water boiler, this boiler can be fully burned fuel in limited furnace cavity, makes the heat energy of high-temperature region, low-temperature space can both carry out sufficient heat exchange, improves the thermal efficiency of stove greatly.
The technical scheme that its technical problem that solves the utility model adopts is: the hot-water boiler body of heater is cylindrical, top at burner hearth is provided with the heat exchanger up and down that communicates with flue respectively with the bottom, the weldering of shrouding excircle and inboard wall of furnace is one about the heat exchanger, burner hearth is separated into upper, middle and lower three parts, constitutes horizontal water-flow circuit with flue.
What be provided with between two heat-exchanger that two rows communicate with flue intersects the hot-water circulation pipe in length and breadth, constitutes netted closed circuit.Furnace gall head adopts circular arching section structure.On the body of heater of two heat-exchanger top position, be provided with deashing air register up and down, fired state is regulated.Improve the flow distribution and the heat-exchange capacity of flue gas by above measure.
Fuel at first carries out heat exchange with following heat exchanger in the lower combustion chamber burning, high-temperature flue gas divides middle part and the netted closed circuit that fire tube enters burner hearth by heat exchanger and goes up heat exchanger and carry out heat exchange, and divides fire tube to enter upper furnace and heat exchange is carried out on flue top after go up heat exchanger.Make the heat energy of burner hearth high-temperature region and low-temperature space can both carry out sufficient heat exchange and reach the energy-conservation purpose that improves the thermal efficiency greatly.
The beneficial effects of the utility model are that fuel is fully burned, and the heat energy of high-temperature region and low-temperature space can both carry out sufficient heat exchange, improve the thermal efficiency of stove greatly.
