Description

Two purpose boiler

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

Present stage, city dweller particularly outskirts of a town, small towns etc. disperses dwelling house resident warming, often adopts 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.Chinese patent CN93207565 number a kind of hot-water boiler is disclosed in the recent period again, it comprises body of heater, furnace water jacket, furnace lining, fire grate, fire door, the stove tube, ash door and water inlet pipe and outlet pipe, and 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 plate washer shelves on the blower fan hole.In stove tube flue, be provided with

The stove tube water pipe of type mainly is to improve total thermal efficiency.The type stove tube water pipe structure here is unreasonable, is unfavorable for smooth and easy the flowing through of water and influences use, in addition, only adopts a return pipe that is set in place on the furnace water jacket at furnace lining place to carry out circulation heating in this technology, unfavorable circulation, and non-uniform temperature, and energy-saving effect is poor.

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, under the prerequisite that guarantees firing rate and higher thermal efficient, use easy and simple to handlely, safe and reliable, and stove tube water pipe project organization is reasonable, the circulating water flow dynamic resistance is little, a kind of dual-purpose hot-water boiler of Remarkable Energy Saving.

The utility model is achieved by following manner: a kind of dual-purpose hot-water boiler, comprise body of heater, furnace water jacket, that the body of heater internal upper part is provided with and internal and external circulating water cover that be communicated with furnace water jacket by upper hose and downcomer, furnace lining, fire grate, stove tube water jacket and interior stove tube water pipe thereof, ash door and blower fan hole thereof, principal character of the present utility model is: the stove tube water pipe that is provided with in the said stove tube water jacket is designed to reduce the L type stove tube water pipe of circulating water flow dynamic resistance, and this stove tube water pipe can directly be communicated with interior cyclic water jacket, and L type stove tube water pipe replaces original here

Type stove tube water pipe, L type stove tube water pipe be communicated with interior cyclic water jacket replaced original

The structure that type stove tube water pipe is connected with stove tube water jacket, this L type stove tube water pipe had both reduced the resistance that recirculated water flows, simplify the structure again simultaneously, be convenient to processing and manufacturing, outer circulation water jacket bottom at the internal and external circulating water of body of heater internal upper part setting cover is provided with return pipe on, go up return pipe like this, internal and external circulating water cover (cyclic water jacket and outer circulation water jacket promptly), stove tube water pipe, stove tube water sleeve outlet pipe has constituted last water return loop, corresponding furnace water jacket bottom in the furnace lining correspondence is provided with a water pipe next time, thereby by water pipe next time, furnace water jacket, stove tube water sleeve outlet pipe has constituted the lower water-back loop, two water return loops by above-mentioned last water return loop and lower water-back loop formation, make present technique can guarantee the normal circulation of recirculated water and make full use of heat energy, improve the thermal efficiency.

The utility model is compared with prior art, can cook and can warm oneself compact conformation except having, outside the characteristics such as heating surface area is big, it is reasonable also to have stove tube water pipe structure simplicity of design, and the circulating water flow dynamic resistance is little, characteristics such as make full use of heat energy, the thermal efficiency is higher, and energy-saving effect is remarkable.
