Abstract
The utility model discloses a stage jumping natural circular water heating boiler which comprises a lower boiler body filled with circular water, wherein, a fume outlet of the lower boiler body is provided with an independent upper boiler body filled with circular water, the lower boiler body is provided with a water supply pipe, the upper boiler body is provided with a water return pipe, and a communicating pipe is arranged to be communicated with the lower boiler body and the upper boiler body. The utility model reasonably uses the heat of fume and gas, effectively prevents the heat dissipation of fume and gas, reduces the pollution of fume and gas for environment simultaneously and has the advantages of fast heating, high heat efficiency, small heat loss, simple structure, small size and low cost.
Description
The utility model relates to a kind of boiler, relates to a kind of hot water boiler with natural circulation of bypassing the immediate leadership with warming installation specifically.
Along with the little disconnected raising of people's living standard, there are not the rural area of central heating and cities and towns warming generally to adopt boiler band warming installation now.Present employed hot water boiler with natural circulation, substantially all adopt the Convective Heating method, be that return pipe is installed in the body of heater bottom, feed pipe is installed in upper of furnace body, fast in order to heat like this, make the circulating water temperature height in the body of heater, will in the limited heating surface area of boiler, improve the combustion heat of fuel, this just needs to produce between stove fire and flue gas and the heated recirculated water the very big temperature difference, so also just caused the temperature of the flue gas of discharging from flue to be higher than far away also that the temperature of recirculated water just has been wasted in the body of heater, thereby this type of boiler all exists heat loss due to exhaust gas, in order to reduce heat loss due to exhaust gas, can take to increase the method for the heating surface area of boiler tail flue, but be heated recirculated water and the flue gas temperature difference is ever-reduced influences, increased the boiler of afterbody flue, effect aspect the raising thermal efficiency is unsatisfactory, and the cost of boiler is very high.
The purpose of this utility model is to provide a kind of heating fast, thermal efficiency height, and heat loss is little, and is simple in structure, and cost is low, can effectively reduce the hot water boiler with natural circulation of bypassing the immediate leadership of smoke pollution.
The purpose of this utility model is achieved in that
The utility model comprises the lower furnace body of dress recirculated water in one, the upper furnace body of dress recirculated water in the outlet flue place of this lower furnace body installation one independently, on said lower furnace body, feed pipe is installed, on said upper furnace body, install back water pipe, be communicated with said lower furnace body and upper furnace body respectively a connecting pipe is installed.
Bottom at said upper furnace body installs back water pipe, on the top of said lower furnace body feed pipe is installed, and the delivery port of said communicating pipe is installed in the top of upper furnace body, and the water inlet of said communicating pipe is installed in the bottom of lower furnace body.
In said upper furnace body, weld an endothermic tube that is communicated with the upper furnace body water jacket at least.
Advantage of the present utility model is:
Because return pipe is installed on the upper furnace body, the low-temperature circulating water that is circulated to upper furnace body is bigger with the temperature difference that flow to the upper furnace body flue gas, recirculated water in the upper furnace body can fully absorb the heat of flue gas, the recirculated water heating of upper furnace body will be entered, reasonably absorbed the heat of boiler tail flue gas, significantly reduced exhaust gas temperature, improved the thermal efficiency, recirculated water after the heating enters lower furnace body by communicating pipe again, can reach the heat of heating service facility very soon after the heated recirculated water of lower furnace body absorbs combustion chamber fuel combustion heat, thereby it is fast to play heating, thermal efficiency height, the effect that heat loss is little has also reduced the pollution of flue gas to environment simultaneously.The utlity model has simple in structurely, volume is little, the advantage that cost is low.
Further advantage of the present utility model is:
Because endothermic tube has been installed in upper furnace body, so, further having increased the heating surface area of upper furnace body, it is minimum that the heat loss of flue gas is dropped to, thereby make the thermal efficiency higher, and heat loss is littler.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, lower furnace body 5 bottoms of interior dress recirculated water are stone or metal plate for standing a stove on as a precaution against fire, it above the stone or metal plate for standing a stove on as a precaution against fire combustion chamber, blow-on door on the lower furnace body on stone or metal plate for standing a stove on as a precaution against fire, the upper furnace body 3 of dress recirculated water in the outlet flue place of said lower furnace body installation one independently, send out in this upper furnace body and adorn two endothermic tubes 2 that are communicated with upper furnace body recirculated water, to increase the heating surface area of upper furnace body, feed pipe 8 is installed on top at said lower furnace body, install back water pipe 7 in the bottom of said upper furnace body, be communicated with said lower furnace body and upper furnace body respectively a connecting pipe 4 is installed, the delivery port 1 of this communicating pipe is installed in the top of upper furnace body, water inlet 6 is installed in the bottom of lower furnace body.During use, recirculated water enters upper furnace body through the return pipe circulation, the flow through flue gas of upper furnace body, the recirculated water heating that will enter upper furnace body, the recirculated water after the heating enters lower furnace body by communicating pipe again, can reach the heat of heating service facility behind the recirculated water absorption combustion heat that lower furnace body has been preheated very soon, so the heating of this boiler is fast, thermal efficiency height, heat loss is little, simple in structure, cost is low.
