Description

Dual-purpose lut water boiler

The utility model relates to a kind of civil boiler, particularly a kind of energy-saving dual-purpose hot-water boiler.

Present stage, the city dweller is outskirts of a town particularly, and small towns etc. disperse the warming of dwelling house, often adopt self-control boiler band soil heating installation.This boiler combustion condition is poor, and the thermal efficiency is low.For this reason people's development and design various civil boilers, a kind of double water jacket energy-saving water-heating dual-purpose stove is disclosed as Chinese patent CN89200041 number, it conducts with heat radiation and heat and heat exchange is carried out in convection current, its inner water sleeve be two-sided be heated and reflection fire lid back be set form the combustion chamber, though this technology has the fast characteristics of firing rate, but its fuel consumption is bigger, therefore is unfavorable for applying.

The utility model improves at the problem that prior art exists, provide a kind of suitable urban and rural residents to use, not only can cook but also can warm oneself, simple in structure, heating surface area is big, and under the prerequisite that guarantees firing rate and higher thermal efficient, energy-saving effect is remarkable, use dual-purpose hot-water boiler easy and simple to handle, safe and reliable.

The utility model is achieved by following manner: a kind of dual-purpose hot-water boiler, comprise body of heater, furnace water jacket, the furnace lining that is provided with on the body of heater, fire grate, fire door, the stove tube, ash door and water inlet pipe and outlet pipe, it is characterized in that: in the body of heater internal upper part is provided with, the outer ring water jacket, the inside-and-outside ring water jacket is fixed by upper hose and downcomer and is communicated with and is communicated with furnace water jacket, be provided with the circular hole of being convenient to the flue gas circulation at the outer ring water jacket place corresponding with the floss hole of stove tube, at interior ring-shaped water jacket top the inner flue cover plate is set, it is along the center of circle to be shaped on the left circles cambered surface of inner flue cover plate of fan beam correspondence of hexagonal angle is convenient to the uniform exhanst gas outlet of furnace temperature, be provided with the stove circle at the body of heater upper top, can put pot etc. herein and cook and cooking.On the sidewall of grey chamber or the ash door blower fan hole being set below fire grate, mainly is bad at the stove combustion case, and standby when needing air blast combustion-supporting, this blower fan hole cooperates with the air outlet of air blast, and the time spent can be with blower fan hole baffle plate retaining on the blower fan hole.In stove tube flue, be provided with

The stove tube water pipe of type mainly is the utilization rate that improves heat energy, to improve total thermal efficiency.Present technique can be removed some parts according to the difference of instructions for use, as removing on former basis Type stove tube water pipe becomes the structure shown in Fig. 4-6; Just become the structure shown in Fig. 7-9 as on former basis, removing the outer ring water jacket; As on former basis, both removing

Type stove tube water pipe removes the outer ring water jacket again and just becomes Figure 10-12 structure; The inside and outside annular water jacket that and for example gets on to fall on former basis just becomes the structure of Figure 13-15.

The course of work of the present utility model is divided the two large divisions: at first be the circulation feedwater, be that water is in water inlet pipe enters pot body water jacket, along with interior, the heating of outer ring water jacket, the circulation separated into two parts when furnace water jacket and outer ring water jacket downcomer place that feeds water, a separated into two parts when part continues to flow to boiler clothing downcomer place, a part continues to flow to the furnace water jacket top, another part flows into respectively in outer ring water jacket and the interior ring-shaped water jacket, after continuing heating, hot water flows back to the furnace water jacket top by upper hose respectively, flow at last in the stove tube water jacket, stove tube water pipe feedwater be stove tube water jacket bottom behind stove tube water pipe, deliver in the heating plant (being radiator) through outlet pipe with the hot water that flows to stove tube water jacket top.Secondly (being second largest part) is the boiler smoke cyclic process, the burner hearth that is surrounded by furnace lining is contained on the fire grate in the body of heater, this furnace lining can improve furnace temperature, improve burning condition, during burning boiler, can take down stove circle and inner flue cover plate thereof, adding fuel in inner flue (can be bavin or coal, the design is to burn coal), coal is heated based on radiation at burner hearth internal combustion rear furnace body, treat then to be heated after flue gas enters flue with convection current and heat conduction, the high-temperature flue gas that flows out from burner hearth is divided into three parts, first enters the outer ring flue, the circular hole that is provided with on it has guaranteed the unimpeded of flue gas, second portion enters annular flue, third part enters inner flue, this partial fume amount is bigger, temperature is higher, therefore place pot etc. on the stove circle and can cooking make meal, when not cooking, can cover the inner flue cover plate, when covering the inner flue cover plate, the exhaust gas volumn of three parts tends to balance, and one side of stove nozzle position opposite (promptly with) exhanst gas outlet flows out the flue gas of the inner flue of flowing through this moment from the right side of inner flue cover plate, and along top wraparound stove tube flue in the body of heater, like this can be fully and furnace water jacket, in, the heat exchange of outer water jacket, when three partial fumes flow to the stove tube and after stove tube water jacket and the heat exchange of stove tube water pipe, exhaust gas temperature is reduced to minimum, be discharged in the atmosphere after flowing to wall with flues or fiery pit at last, this designing and arranging fume and dust effect is better, alleviated environmental pollution, deashing is also more convenient, promptly moves several times along each flue successively with the stove hook to get final product.

The utility model is compared with prior art, has compact conformation, and is easy to operate, and heating surface area is big, and firing rate is fast, and burning condition is good, good energy-conserving effect, and the thermal efficiency is higher, characteristics such as long service life.
