Abstract
The utility model discloses an upper backwater energy saving boiler. A water-jacketed lower furnace body for circulating water arranged inside the boiler is provided with a water-jacketed upper furnace body on it. The top of the combustion chamber of the lower furnace body is provided with a smoke outlet, the smoke outlet is communicated with the furnace hearth of the upper furnace body and the top of the upper furnace body is connected with a chimney. A water inlet pipe of the lower furnace body is connected with the water jacket of the upper furnace through a connection pipe and the upper section of the lower furnace is connected with a water outlet pipe. The utility model is provided with the lower furnace body and the upper furnace, the combustion heat of the fuel heats the circuiting water jacket of the lower furnace body, and the smoke with the residual heat at the same heats the circuiting water jacket of the upper furnace body, therefore the water jacket of the upper furnace body is preheated, the preheated circuiting water enters into the water jacket of the lower furnace body and the entry water of the lower furnace is warm water, thus enhancing the utilization rate of the flue, increasing the heat efficiency, saving the flue, shortening the heating time and speeding up heating; the utility model features simple structure and low cost.
Description
Technical field the utility model relates to a kind of boiler, relates to a kind of last backwater power economized boiler of civilian band warming installation specifically.
Background technology is along with cities and towns, rural area, pastoral area warming adopt increasing gradually of civil boiler, the kind of civil boiler is also a lot of in the market, using many is interior dress circulating water pipe or the miniature boiler that adopts furnace water jacket, because this class boiler volume is little, cost is low, so relatively be suitable for civilian band warming installation heating.Present employed civil boiler, basically the flue gas of fuel combustion generation is directly discharged through chimney, the time that flue gas is detained in boiler is shorter, part of waste heat in the flue gas is not recycled water and just fully absorbs directly discharge, cause the loss of heat, make the recirculated water heating slow, the thermal efficiency is low, waste fuel; In order to improve the thermal efficiency, some boiler structurally improves to some extent, but this class boiler structure relative complex often, cost is higher; Owing to contain a certain amount of not burned material in the flue gas, certain pollution is caused to environment in the discharging back, is unfavorable for environmental protection simultaneously.
The summary of the invention the purpose of this utility model is to provide a kind of combustion heat that can fully absorb fuel, improves the thermal efficiency, last backwater power economized boiler simple in structure, with low cost.
The purpose of this utility model is to realize by following technical scheme:
A kind of backwater power economized boiler of going up, its structural feature is: the water-jacket typ upper furnace body is installed above the water-jacket typ lower furnace body of interior dress recirculated water, said lower furnace body top of combustion chamber is provided with outlet flue, this outlet flue is communicated with the upper furnace body burner hearth, the upper furnace body top connects chimney, the water inlet pipe of said lower furnace body connects the upper furnace body water jacket by connecting tube, and said lower furnace body top connects outlet pipe.During use, fuel is in the combustion chamber of lower furnace body internal combustion, the cyclic water jacket of combustion heat heating lower furnace body, the flue gas that has a waste heat enters upper furnace from the outlet flue of lower furnace body, the cyclic water jacket of the waste heat heating upper furnace body of flue gas, make the cyclic water jacket preheating of upper furnace body, the recirculated water that is preheated enters the lower furnace body cyclic water jacket by connecting tube, and the water inlet that makes lower furnace body is a warm water.
Said lower furnace body is provided with the endothermic water tank in the combustion chamber, and this endothermic water tank connects the lower furnace body water jacket by the connection pipe.Because the endothermic water tank has been installed, so the combustion heat of fuel can directly heat the endothermic water tank, heat absorption is fast.
Said endothermic water tank is two.
Being provided with the heat absorption water plate that is communicated with furnace water jacket in the said lower furnace body combustion chamber, is the through hole of logical flue gas in the middle of this heat absorption water plate.
The water jacket case is installed in the said upper furnace body, and this water jacket case is communicated with the upper furnace body water jacket by the connection pipe.
Between said lower furnace body and the upper furnace body thermal insulation layer is set.
Advantage of the present utility model is: the utility model is provided with lower furnace body and upper furnace body, the cyclic water jacket of fuel combustion heat heating lower furnace body, the flue gas that has waste heat heats the cyclic water jacket of upper furnace body simultaneously, makes the cyclic water jacket preheating of upper furnace body, and the recirculated water that is preheated enters the lower furnace body cyclic water jacket by connecting tube, the water inlet that makes lower furnace body is a warm water, improved the utilization rate of fuel, increased the thermal efficiency, fuel saving, shorten heat time heating time, heating is fast; The utility model is simple in structure, and is with low cost.
The further advantage of the utility model is: because endothermic water tank, heat absorption water plate further are installed in the combustion chamber, make the heat of combustion chamber faster, the more direct water that is recycled absorbs, and can prevent that heat scatters and disappears from body of heater, the thermal efficiency improves, and heating rapidly.
Description of drawings Fig. 1 is a structural representation of the present utility model.
The specific embodiment as shown in Figure 1, a kind of backwater power economized boiler of going up, above the water-jacket typ lower furnace body 8 of interior dress recirculated water water-jacket typ upper furnace bodies 3 are installed, 9 tops, lower furnace body combustion chamber are provided with outlet flue 11, this outlet flue is communicated with the upper furnace body burner hearth, the upper furnace body top connects chimney 12, the water inlet pipe of said lower furnace body connects the upper furnace body water jacket by connecting tube 10, said lower furnace body top connects outlet pipe 5, said upper furnace body top is provided with return pipe 1, said lower furnace body is provided with in the combustion chamber, following two endothermic water tanks 6, this endothermic water tank connects the lower furnace body water jacket by the connection pipe, be provided with the heat absorption water plate 7 that is communicated with furnace water jacket in the said lower furnace body combustion chamber, in the middle of this heat absorption water plate is the through hole of logical flue gas, water jacket case 2 is installed in the said upper furnace body, and this water jacket case is communicated with the upper furnace body water jacket by the connection pipe, and thermal insulation layer 4 is set between said lower furnace body and the upper furnace body.
